Security liberies

Modern systems are increasingly equipped with connectivity features that also make them more vulnerable to attacks. Therefore, it is mandatory to protect these systems against unauthorized access by intruders and to prevent any attempt to manipulate the systems software.

For security at systems level, software based security solutions cannot sufficiently protect the integrity of a system. Hardware Security Modules (HSM) provide embedded systems with strong protection against attacks and thus strengthen the integrity of the software. ESCRYPT CycurHSM is a complete software stack adapted to automotive HSM implementations. ESCRYPT CycurHSM is a flexible HSM firmware that provides open and standardized interfaces to HSM-enhanced security applications.
