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.
