Philip Hawkes & Rick Wietfeldt, Co-Chairs of the MIPI Security Working Group

The MIPI CSI-2® security framework for ADAS/ADS provides data protection of camera connectivity to ECUs, and includes component authentication, integrity, and optional confidentiality. Its key features are:

  • CSI-2 protocol-based end-to-end data security with and without SerDes bridges
  • Highly-granular security control of the CSI-2 video frame, known as Source-selective partial-integrity and encryption (SSPIE)
  • Operation natively over MIPI A-PHY® and SerDes bridges that support CSI-2 via MIPI C-PHY℠/D-PHY℠ interface
