  • Publication number: 20090327812
    Abstract: Exemplary embodiments of a method, device and computer-accessible medium for secure access protocol conformance testing on an authentication service entity can be provided. According to one exemplary embodiment, it is possible to determine whether a certificate issued by the authentication service entity to be tested complies with a corresponding specification of a standard. An authentication requester can be simulated to send a certificate authentication request message to the authentication service entity to be tested. A certificate authentication response fed back from the authentication service entity to be tested can be captured. Further, a secure access protocol conformance testing result on the authentication service entity to be tested can be obtained by analyzing the certificate authentication response.

  • Publication number: 20090013378
    Abstract: The invention relates to a method and device for testing conformity of a secure access protocol at an access point. The method includes the steps of: capturing a data packet of a secure access protocol in a secure access authentication process at an access point under test; and analyzing and checking an encapsulation format of the captured data packet of the secure access protocol and a protocol flow. With the invention the test result is independent of the implementation of an upper-layer protocol, and a correct test result can be obtained regardless of deviant implementation of a reference equipment, to thereby improve correctness of the test result. With the invention, an error in the implementation of the protocol can also be located precisely in accordance with detailed information obtained from the data packet of the protocol, and a simulative test of a possible exception is introduced, thereby ensuring that a product which passes the test conforms to the standard and interoperability.
