    MIPI Security Investigation Group – A Conversation with Philip Hawkes and Rick Wietfeldt

    Formed in 2019, the MIPI Security Investigation Group (Security IG) was established to provide recommendations for a scalable, uniform MIPI security framework and ongoing support model, as well as to offer guidance to MIPI working groups on overarching security requirements, guiding principles and policies, and external threats. 

    Recently the group achieved a significant milestone in evaluating approaches to secure systems-on-chips (SoCs) in automotive electronic control units (ECUs) to peripherals such as cameras, sensors and displays in support of MIPI’s automotive work. As part of this effort, the Security IG conducted a technical and strategic evaluation of DMTF’s Security Protocol and Data Model (SPDM) architecture, which provides message exchange, sequence diagrams, message formats and other relevant semantics for authentication, firmware measurement and certificate management. The evaluation confirmed that the SPDM architecture meets MIPI’s requirements for this use case. We sat down with Philip Hawkes and Rick Wietfeldt, co-chairs of the Security IG, to learn more.

    MIPI Protocol Adaptation Layers (PALs) — A Conversation with Raj Kumar Nagpal

    MIPI Alliance is rolling out a portfolio of Protocol Adaptation Layers (PALs) to support a range of important automotive sensor and display applications—advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and in-vehicle infotainment (IVI), among others. The PALs enable upper-layer protocols such as MIPI Camera Serial Interface (CSI-2®) and Display Serial Interface (DSI-2SM) to be transported over MIPI A-PHYSM, the first industry-standard, long-reach serializer-deserializer (SerDes) physical layer interface.

    Raj Kumar Nagpal, interim chair of the MIPI PHY Working Group and lead of the MIPI A-PHY Subgroup, talks about how the PALs support A-PHY, as well as their contribution to the broader system of MIPI automotive connectivity solutions currently under development.

    MIPI in the News: A-PHY in EE Times and RFFE in IEEE Future Networks

    Two of the most significant MIPI highlights of 2020 were the eagerly anticipated releases of MIPI RFFE v3.0SM in April and MIPI A-PHYSM v1.0 in September. With the rollout of 5G well underway, and the rapid advancements in ADAS, ADS and IVI automotive applications, these specifications have generated tremendous interest for their roles in enabling these profound transformations.

    To share more about what these new specifications bring to their respective ecosystems, both were recently highlighted in industry publications. Here’s a look:

    The Power of Collaboration — A Conversation with Joel Huloux

    Recently MIPI Alliance announced it had signed a memorandum of understanding (MoU) with IEEE, the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. Under the agreement, MIPI A-PHYSM v1.0 will be brought forward through the adoption process to become an IEEE standard. In this Q&A, Joel Huloux, chairman of MIPI Alliance, discusses the significance of this announcement and the importance of liaison relationships, and shares a look ahead at what’s to come for MIPI Alliance.

    Advancing Automotive Interoperability, Choice and Economies of Scale via Collaboration with IEEE

    The MIPI A-PHYSM v1.0 specification, which has been available to MIPI Alliance members since September 2020, is now positioned for wider availability to the broader automotive ecosystem.

    As detailed in an October 13 press release, under terms of a memorandum of understanding (MOU) with IEEE, the A-PHY serializer-deserializer (SerDes) specification will be put forward for adoption as an IEEE standard, which will result in broader global availability and, ultimately greater interoperability, choice and economies of scale for the global automotive industry.

    MIPI Debug for I3C v1.0 Now Available

    The smaller and more power-constrained systems being developed today for the Internet of Things (IoT), mobile devices, automotive and other use cases demonstrate the value of low-bandwidth interfaces for debug and trace. At the same time, the flexibility and scalability that these new use cases require have revealed crucial shortcomings in legacy low-bandwidth interfaces that are structured statically, such as JTAG/cJTAG, I2C and UART.
