As the need for security becomes increasingly more critical, MIPI Alliance has continued to broaden its portfolio of standardized solutions, adding two more specifications in late 2025, and continuing work on significant updates to the MIPI Camera Security Framework specifications slated for completion in mid-2026.

Read on to learn more about the newly released specifications and what lies ahead for the MIPI Camera Security Framework.

MIPI CCISE: Protecting Camera Command and Control Interfaces

The new MIPI Command and Control Interface Service Extensions (MIPI CCISE) v1.0, released in December 2025, defines a set of security service extensions that can apply data integrity protection and optional encryption to the MIPI CSI-2® camera control interface based on the I2C transport interface. The protection is provided end-to-end between the image sensor and its associated SoC or electronic control unit (ECU).

MIPI CCISE rounds out the existing MIPI Camera Security Framework, which includes MIPI Camera Security v1.0, MIPI Camera Security Profiles v1.0 and MIPI Camera Service Extensions (MIPI CSE) v2.0. Together, the specifications define a flexible approach to add end-to-end security to image sensor applications that leverage MIPI CSI-2, enabling authentication of image system components, data integrity protection, optional data encryption, and protection of image sensor command and control channels. The specifications provide implementers with a choice of protocols, cryptographic algorithms, integrity tag modes and security protection levels to offer a solution that is uniquely effective in both its security extent and implementation flexibility.

Use of MIPI camera security specifications enables an automotive system to fulfill advanced driver-assistance systems (ADAS) safety goals up to ASIL D level (per ISO 26262:2018) and supports functional safety and security mechanisms, including end-to-end protection as recommended for high diagnostic coverage of the data communication bus.

While the initial focus of the camera security framework was on securing long-reach, wired in-vehicle network connections between CSI-2 based image sensors and their related processing ECUs, the specifications are also highly relevant to non-automotive machine vision applications that leverage CSI-2-based image sensors.

A downloadable white paper, A Guide to the MIPI Camera Security Framework for Automotive Applications, provides a detailed explanation of how these specifications work together to provide application layer end-to-end data protection.

MIPI Security Specification for Debug: Enabling Remote Debug of Systems in the Field

The recently adopted MIPI Security Specification for Debug defines a standardized method for establishing secure, authenticated debug sessions between a debug and test system and a target system.

Designed to enable remote debugging in potentially hostile real-world locations outside of a test lab, the specification allows secure remote debugging of production devices without relying solely on traditional physical protections such as buried traces or restricted access to debug ports. Instead, it introduces a trusted, cryptographically protected communication path that spans end-to-end, from the physical debug tool to the target device’s package pins, through all connectors, cabling, routing and bridges.

The new speciation adds a secure messaging layer to the existing MIPI debug architecture, wrapping debug traffic in encrypted, authenticated messages while remaining interface-agnostic. Core components include a secure communications manager that is responsible for security protocol, data model processing and key generation; cryptographic message-protection functions; and secure communication management paths. To accomplish this, the specification leverages the DMTF Security Protocol and Data Model (SPDM) industry standard for platform security.

This approach ensures authenticity, confidentiality and integrity for all debug communications, regardless of the underlying transport interface, whether MIPI I3C®, USB, PCIe or others. Debugger behavior remains consistent across interfaces, simplifying implementation and validation.

The specification complements the broader MIPI debug ecosystem.

Coming in 2026: New “Fast Boot” Options for MIPI Camera Security

Enhancements to the suite of MIPI camera security specifications are being developed to enable faster boot times for imaging systems, minimizing the time taken from power-on to streaming of secure video data.

These enhancements will continue to leverage the DMTF SPDM framework and message formats, but will introduce an optional new security mode that will half the number of security handshake operations required to complete the establishment of a secure video streaming channel compared with currently defined security modes. Image sensors will be able to implement both current and new modes of operation to provide backward compatibility, and SoCs may only require software updates to implement the new mode of operation.

Both the MIPI Camera Security and the MIPI Camera Security Profiles specifications are scheduled to be updated to v1.1 in mid-2026. However, the companion specifications that will fully enable the enhancements, MIPI CSE v2.1 and the new CSE Exchange Format (EF) v1.0, will follow later this year.

All security specifications are currently available only to MIPI Alliance members.

As embedded audio systems continue to evolve across consumer electronics, automotive and industrial applications, so does the demand to deliver advanced features—such as far-field voice recognition, spatial audio and “always-on” AI-driven audio processing—within increasingly compact, power-sensitive devices such as smart glasses and earbuds, and larger devices such as cars and industrial robots. The recently released MIPI SoundWire I3S (SWI3S) v1.0 is a new audio interface purpose-built to meet the growing complexity of modern embedded audio systems. The new specification, supporting a link bandwidth of up to 76 Mbps, provides a transformative approach to audio transport by unifying control and data over a single, scalable, low-latency, power-efficient interface.

Limitations of Legacy Interfaces

Legacy audio interfaces like I2S and TDM were not designed to handle the complexity and EMI challenges of today’s systems. These older technologies often require multiple lines for data, control and clocks—leading to increased pin count, board complexity and susceptibility to interference, particularly over long traces or flexible cables.

SWI3S Solves Today’s Audio Integration Challenges

MIPI SWI3S, developed by the MIPI Audio Working Group, builds upon the proven two-pin, multi-drop architecture of MIPI SoundWire®, introducing greater flexibility and performance. It supports both differential low voltage (DLV) and forwarded bit clock single-ended (FBCSE) PHYs, allowing designers to select the PHY that best meets system requirements, while maintaining a unified protocol and core set of features. SWI3S enables scalable tiered topologies with each link comprising one manager and up to 12 audio peripherals (e.g., microphones, speakers, amplifiers, haptic drivers, hearing aid coils), making it ideal for audio systems of any complexity.

Key features include standardized advanced power management, link-wide multi-channel synchronization, precise audio clock distribution and robust in-band command transport. It also incorporates built-in EMI reduction techniques, such as data scrambling, and offers native test and debug support.

What’s Ahead for SWI3S

The working group is already working on the next version of SWI3S — v1.1 — which will add support for hub-based and tiered topologies to allow peripherals to act as hubs to extend the SWI3S links to downstream devices. Further, since SWI3S can support multiple PHY types, the hub-based topology will also support mixed-PHY environments.

These features will allow designers to optimize each segment of the audio path based on the physical layout, EMI constraints and power budgets of each audio subsystem, without having to change the high-level transport or control protocols. For even more flexibility, version 1.1 will also add support for a single data rate single-ended PHY, as well as support for running SWI3S protocol over the MIPI SoundWire PHY. These updates are expected to be available in early 2027.

Resources for Implementers

MIPI offers resources and tools for developers interested in the SWI3S specification.

• A SWI3S visualizer tool helps implementers configure the DataPort parameters and visualize the resulting traffic patterns on the SWI3S bus, enabling experimentation with bandwidth allocation
• A newly published technical brief offers in-depth details on the specification’s key features, along with a comparison of SWI3S vs. other MIPI and non-MIPI audio interfaces. It also provides a sneak peek into future features, including support for hub-based and tiered topologies.

BRIDGEWATER, N.J., October 29, 2024—The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, today announced the release of the MIPI Camera Security Framework, which defines a flexible approach to add end-to-end security to automotive applications that leverage the MIPI Camera Serial Interface 2 (CSI-2) interface specification.

Because of the safety-critical role of image sensors in advanced driver-assistance systems (ADAS) and autonomous driving systems (ADS), protecting image-sensor data against cybersecurity risks is paramount to the security of the overall vehicle. Advanced image sensor-enabled systems must be secured from cybersecurity risks such as installation of illegitimate or substandard image sensor components, malicious manipulation of sensor data and privacy violations from unauthorized access to images and image-related metadata.

Uniquely effective in both implementation and operational flexibility, the new MIPI Camera Security Framework enables authentication of system components, data integrity protection and data encryption. It provides implementers with a choice of security protocols, cipher suites, data integrity tag modes and security controls, which together provide a high degree of flexibility to balance required security levels against processing efficiency, implementation complexity, thermal regulation and power consumption.

While other embedded interface security methods protect only the link layer, the MIPI Camera Security Framework delivers application-level protection from “silicon to silicon” —the security transcends all link-layer components to provide end-to-end CSI-2 protection from the source of sensor data in sensor silicon to the ultimate sink of that data in system-on-chip (SoC) silicon.

In this way, end-to-end CSI-2 protection is guaranteed, irrespective of the underlying communication network topology, providing complete flexibility for developers to leverage any combination of bridges, aggregators, forwarding elements and other underlying network components to achieve the most efficient solution for their particular application.

The MIPI Camera Security Framework also allows highly granular security control over the different segments of the CSI-2 image frame to enable a “sliding scale” of security levels. At the highest security level, full data integrity and encryption are applied to the whole image frame; whereas, at partial integrity levels, integrity protection is applied to a subset of data within an image frame. At the lowest security level, no data integrity is applied to the image data. The level of security is configurable on a frame-by-frame basis.

Although the framework has been designed for protection of automotive data streams, it can be applied to Internet of Things (IoT), industrial and other use cases that leverage CSI-2-based image sensors for machine-vision applications.

The MIPI Camera Security Framework currently consists of three new specifications, with a fourth to be added in the coming months:

• MIPI Camera Service Extensions (MIPI CSE) v2.0, a companion specification to MIPI CSI-2, defines security services to enable data integrity protection and optional encryption of CSI-2 data (in addition to the functional safety services provided in CSE v1.0).
• MIPI Camera Security v1.0, which defines system security management of MIPI CSE and the upcoming MIPI CCISE, leveraging the Distributed Management Task Force (DMTF) Security Protocol Data Model (SPDM) for authentication of system components.
• MIPI Camera Security Profiles v1.0, which defines a set of common security profiles for the MIPI Camera Security Framework to enable interoperability, including profiling of SPDM authentication mechanisms.
• MIPI Command and Control Interface Service Extensions (MIPI CCISE) v1.0, another companion specification to MIPI CSI-2, will define security services to enable data integrity protection and optional encryption of the MIPI Command and Control Interface (MIPI CCI) based on I²C. This specification is under development with completion expected by the end of 2024.

The new security framework is a key component of the MIPI Automotive SerDes Solutions (MASS) full stack of connectivity solutions, and the new security services within the framework are fully complementary to the functional safety services that have already been introduced.

“With the widespread use of CSI-2-based image sensors within automotive, the introduction of the MIPI Camera Security Framework significantly strengthens and simplifies the protection of camera data streams,” said Sanjiv Desai, chair of MIPI Alliance. “In the past, integrators have had to rely on proprietary security solutions, but now there’s a standardized approach that delivers end-to-end protection, along with the ability to flex the level of protection to suit their particular requirements.”

The framework was the result of collaboration between the MIPI Security Working Group and a subgroup of the MIPI Camera Working Group. Companies participating in the effort include Intel Corporation; Introspect Technology; Mixel, Inc.; Mobileye; NVIDIA; OmniVision Technologies, Inc.; onsemi; Qualcomm Incorporated; Renesas Electronics Corporation; Robert Bosch GmbH; Sony Group Corporation; STMicroelectronics; Synopsys, Inc.; Teledyne LeCroy; Valens Semiconductor; and others.

BRIDGEWATER, N.J., Sept. 26, 2024 — The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, today announced the release of MIPI A-PHY v2.0, the next version of the automotive high-speed asymmetric serializer-deserializer (SerDes) physical-layer interface. Version 2.0 doubles the maximum available downlink data rate from 16 Gigabits per second (Gbps) to 32 Gbps on a single channel, as well as adds an additional uplink gear with an eight-fold speed boost to support up to 1.6 Gbps. These enhancements are designed to support the higher bandwidth requirements for zonal and other emerging architectures in next-generation vehicles.

MIPI A-PHY was purpose-built to provide high-performance links between automotive image sensors and displays and their associated electronic control units (ECUs). It was developed to simplify the integration of greater numbers of onboard sensors and displays for applications such as advanced driver-assistance systems (ADAS), modern digital cockpits, in-vehicle infotainment (IVI) and autonomous driving systems (ADS).

A-PHY offers a reach of up to 15 meters, unprecedented reliability with an ultra-low packet error rate of 10^-19 over a vehicle’s lifetime, high noise immunity and ultra-low latency, along with very low bandwidth channel requirements. It also forms the foundation of MIPI’s Automotive SerDes Solutions (MASS), an end-to-end framework for connecting cameras, sensors and displays with built-in functional safety, security and data protection.

Key Features of A-PHY v2.0

MIPI A-PHY v2.0 features forward-looking enhancements in recognition of the increasing bandwidth and performance requirements needed for software-defined vehicles (SDVs), and zonal and other emerging vehicle architectures:

• PAM4 support now extends up to gear 5 (up to 16 Gbps).
• The addition of two new gears, G6 and G7, with PAM8 and PAM16 encoding, for speeds 24 and 32 Gbps, respectively.
• A faster 1.6 Gbps uplink gear, more than 8 times the data rate of the previous uplink gear, providing support for symmetrical 1 Gbps Ethernet channels over A-PHY links for command and control of automotive peripherals.

To aid implementation, no changes were made in the upper layers of A-PHY v2.0 so that migration from previous versions would have minimal impact. Version 2.0 is fully interoperable with A-PHY v1.1 and v1.0, and devices using all three specifications can coexist on the same network.

“MIPI A-PHY continues to evolve to provide unprecedented bandwidth and increased implementation flexibility while still maintaining its superior noise immunity and resiliency,” said Sanjiv Desai, chair of MIPI Alliance. “This new version allows A-PHY to meet an even greater range of speed and design needs, and provides a strong roadmap to address the future demands of the rapidly evolving automotive industry.”

Compliance Program Development Continues

To support testing and implementation, MIPI Alliance is developing a compliance program to provide OEMs and device manufacturers with assurance that their devices are compliant with the A-PHY specification. The program is being introduced in a phased approach, with the next test event scheduled for early December 2024.
