Patents by Inventor James F. Semple

James F. Semple has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8391841
    Abstract: A mutual authentication method is provided for securely agreeing application-security keys with mobile terminals supporting legacy Subscriber Identity Modules (e.g., GSM SIM and CDMA2000 R-UIM, which do not support 3G AKA mechanisms). A challenge-response key exchange is implemented between a bootstrapping server function (BSF) and mobile terminal (MT). The BSF generates an authentication challenge and sends it to the MT under a server-authenticated public key mechanism. The MT receives the challenge and determines whether it originates from the BSF based on a bootstrapping server certificate. The MT formulates a response to the authentication challenge based on keys derived from the authentication challenge and a pre-shared secret key. The BSF receives the authentication response and verifies whether it originates from the MT.

  • Patent number: 8229118
    Abstract: Systems and methods of securing wireless communications between a network and a subscriber station include inserting a marker denoting an encryption type within a random value used for authentication, calculating a first session key and a first response value as a function of the random value, then calculating a second session key and a second response value as a function of the random value, first session key and first response value. The two levels of session keys and response values may be used by upgraded subscriber stations and network access points to prevent attackers from intercepting authentication triplets.

  • Patent number: 8064602
    Abstract: Systems and methods of securing wireless communications between a network and a subscriber station are disclosed. One embodiment creates authentication triplets due to expire after a certain amount of time such that they may not be used indefinitely by an attacker who intercepts them.
