Escrypt’s CycurHSM is an automotive-qualified embedded security software stack which realizes a security trust anchor for the application utilizing the Infineon AURIX hardware security module (HSM). CycurHSM helps in fulfilling complex OEM security requirements with ease by comprehensive range of cryptographic protocols and algorithms.

With proprietary as well as standardized interfaces on the host side (including CryptoDriver) CycurHSM ensures a smooth integration into any AUTOSAR stack and also into any non-AUTOSAR systems and by this into the overall system architecture.

CycurHSM also meets Functional Safety use cases up to ISO26262 ASIL-D.

The underlying operating system allows multiple session support as well as an efficient and prioritized utilization of the HSM hardware resources including the symmetric and asymmetric hardware accelerators.



  • Secure boot
  • Fail-safe HSM firmware update
  • Secure onboard communication (SecOC), secure logging, secure host flashing, secure debug and secure access
  • Bank swap SOTA support
  • Runtime manipulation detection and many more OEM specific use cases

 All security features and secure data elements are completely configurable to tailor the stack for a particular requirements.
