Abstract
Techniques for computer security, and more specifically timestamp-abased authentication, are described. Some implementations provide an authentication method that utilizes an authentication process that is shared as a secret between a client and an authenticator. The process provides as output a number that is based on a timestamp. To authenticate the client when it attempts to access a target service, both the client and authenticator execute the authentication process using locally generated timestamps. If the outputs of the authentication process match, the client is authenticated. If not, subsequent network communications from the client are either denied or redirected to an alternative computing system that masquerades as the target service.
