ESCRYPT CycurHSM supports cyber resilience from the inside and across all use cases. It can be seamlessly integrated in automotive ECUs.
Get ready for the future with ESCRYPT CycurHSM 3.X
The evolution of the automotive industry towards the software-defined vehicle (SDV) and vehicle computers is transforming cybersecurity requirements. Many current approaches and software solutions are no longer able to support this shift in a safety-compliant and efficient way. We at ETAS provide a future-oriented hardware security module firmware: our latest generation of ESCRYPT CycurHSM 3.X is designed for all future SDV-related cybersecurity challenges.
