Abstract: A method for securing safety-relevant loads in a motor vehicle, including a main path arranged between a sub-on-board electrical system for a safety-relevant load of a motor vehicle and another sub-on-board electrical system for a non-safety-relevant load.

The main path includes at least one switch, and at least one detector for detecting a current flowing through the main path. At least one additional path is provided which is connected in parallel with the main path, the additional path having at least one switch. The method includes: opening the main path upon detection of a critical state, i.e., an overcurrent and/or an undervoltage or overvoltage on the sub-on-board electrical system for the safety-relevant load. The additional path is closed or kept closed while the main path is open. The additional path is subsequently reopened.

Abstract: A method for certificate chain validation is disclosed for memory-efficient execution inside a secure execution environment of a hardware security module (HSM), despite very limited memory being inside the HSM. This is achieved by allocating enough HSM memory for at least the root certificate, a signer certificate, and a certificate to be validated, and replacing the signer certificate as the certificate chain is traversed. Revalidation of data is implemented by computing secure tags that enable the HSM to quickly recognize previously validated data. Chain validation is only considered provisional until checked against a CRL, which can be provided to the HSM in a streaming fashion, and each received serial number in the CRL is checked against the list of serial numbers representing the provisionally verified chain.
