Powerful security software for your ECU

Modern vehicles are increasingly equipped with internet connectivity, which in turn is making vehicle IT systems more vulnerable to attacks. These systems must be protected against unauthorized access by intruders who may attempt to manipulate the ECU software (e.g. tuning) or manipulate the vehicle’s anti-theft mechanism (immobilizer). There is also a risk that criminals could misuse the internet connection of the vehicle to access the in-vehicle communication system and carry out targeted manipulation of the vehicle’s behavior.

ESCRYPT’s CycurHSM product is an innovative and flexible HSM security firmware that ensures secure boot of the ECU, secure in-vehicle communication, ECU component protection and secure flashing.

ESCRYPT now offers webinar 'How to secure automotive ECUs – introducing HSM technology and trusted boot feature' and Whitepaper Implementing chains of trust with CycurHSM.
