Secure credential generation and validation

Abstract:

Techniques for generating and validating credentials are disclosed. A server generates credentials using only a single current key, up to a threshold number of credentials. The server accepts client connection requests with credentials that were generated using n most recently used keys, including the current key and one or more legacy keys. The server rejects connection requests with credentials that were generated using any other key. When the current key has been used to generate the threshold number of credentials, the server updates the current key to a new key.
