Abstract: A system, apparatus, method, and machine-readable medium are described for defending against malicious code injection. For example, one embodiment of an apparatus comprises: a processor to execute an application to access a web page on the Internet in response to user input, the web page having one or more resource descriptors and/or code descriptors associated therewith; an authenticator engine to validate the web page based, at least in part, on the resource descriptors and/or code descriptors, by connecting to a trusted entity; and wherein the trusted entity is configured to generate a signature on a cryptographic assertion that includes one or more resource descriptor objects associated with the one or more resource descriptors and/or one or more code descriptor objects associated with the one or more code descriptors.

Abstract: A system, apparatus, method, and machine-readable medium are described for endorsing authenticators. For example, one embodiment of an apparatus comprises: a first instance of an authenticator associated with a first app to allow a user of the first app to authenticate with a first relying party; a secure key store accessible by the first instance of the authenticator to securely store authentication data related to the first app; and a synchronization processor to share at least a portion of the authentication data with a second instance of the authenticator associated with a second app to be executed on the apparatus.

Abstract: A system, apparatus, method, and machine-readable medium are described for determining the authentication capabilities. For example, one embodiment of a method comprises: receiving a policy identifying a set of acceptable authentication capabilities; determining a set of client authentication capabilities; and filtering the set of acceptable authentication capabilities based on the determined set of client authentication capabilities to arrive at a filtered set of one or more authentication capabilities for authenticating a user of the client.

Abstract: A system, apparatus, method, and machine readable medium are described for transparently requesting a new random challenge from a server within an authentication framework. For example, one embodiment of a method comprises: transmitting a random challenge and an indication of a timeout period associated with the random challenge from a server to a client within the context of a network registration or authentication process using authentication devices communicatively coupled to the client; automatically detecting that the random challenge is no longer valid based on the timeout period; and responsively transmitting a request for a new random challenge from the client to a server, wherein transmitting is performed transparently to a user of the client.
