  • Security token expiration using signing key rotation
    Patent number: 11405197
    Abstract: A method for expiring tokens includes obtaining a list of valid key identifications (IDs) for at least one valid cryptographic key configured to sign authentication tokens. The method also includes receiving an authentication token from a client authenticating and authorizing the client to access a resource and comprising an ID of a cryptographic key used to sign the authentication token. The method also includes determining whether the cryptographic key used to sign the authentication token is valid based on the list of valid key IDs for the at least one valid cryptographic key. When the cryptographic key used to sign the authentication token is valid, the method includes allowing the client access to the resource.
