CHALLENGE-BASED AUTHENTICATION FOR RESOURCE ACCESS

摘要

Examples of the present disclosure describe systems and methods for authentication by an authentication component when a client attempts to access a secured resource(s). As an example, an access request is received from a client at an authentication component. The authentication component generates an authentication challenge including criteria to assist the client in selecting an appropriate authentication credential, a request for proof of possession of the authentication credential, and challenge-specific data for the client to return in a challenge response. A challenge response is received from the client. The authentication component evaluates the challenge response and determines whether to authenticate the client for access to a resource based on the evaluated challenge response. Other examples are also described.
