TECHNIQUES FOR MANAGING CERTIFICATES ON A COMPUTING DEVICE

摘要

Techniques for managing certificates on a computing device are provided. An example method according to these techniques includes receiving an image file comprising a hash value of a certificate on which a certificate action is to be performed, the certificate action being a revocation action or an activation action, the image file having been signed by a signing certificate, determining whether the image file has been signed by a valid certificate by comparing a hash value of the signing certificate to a plurality of hash values associated with certificates stored in a one-time programmable memory of the computing device, and performing the certificate action, responsive to the image file having been signed by the valid certificate and the certificate on which the certificate action is to be performed having been found in the memory, by setting a value of an indicator associated with the certificate in the memory.

1. A method for managing certificates on a computing device, the method comprising:
receiving, at the computing device, an image file comprising a hash value of a certificate on which a certificate action is to be performed, the certificate action being a revocation action or an activation action, the image file having been signed by a signing certificate; determining whether the image file has been signed by a valid certificate by comparing a hash value of the signing certificate to a plurality of hash values associated with certificates stored in a one-time programmable memory of the computing device; and performing the certificate action on the certificate on which the certificate action is to be performed, responsive to the image file having been signed by the valid certificate and the certificate on which the certificate action is to be performed having been found in the one-time programmable memory of the computing device, by setting a value of an indicator associated with the certificate in the one-time programmable memory.
