Latest Patents

Andrew holds a patent for a method titled "HSM-memory-efficient means of providing HSM-based PKI operations for vehicle controllers." This patent describes a method for certificate chain validation that is designed for memory-efficient execution within a secure execution environment of an HSM. The method allows for the allocation of sufficient HSM memory for at least the root certificate, a signer certificate, and a certificate to be validated. As the certificate chain is traversed, the signer certificate is replaced, ensuring efficient memory usage. Additionally, the method implements revalidation of data through the computation of secure tags, enabling the HSM to quickly recognize previously validated data. The chain validation process is considered provisional until it is checked against a Certificate Revocation List (CRL), which can be streamed to the HSM for real-time validation.
