Patent number: 5537474Abstract: A method and apparatus for authenticating a roaming subscriber. In a preferred embodiment, a subscriber receives a challenge that is in a format of a local authentication protocol, and determines whether the local authentication protocol is the subscriber's home system authentication protocol. If it is not, the subscriber converts the challenge into a format (e.g., bit length) compatible with its home system authentication protocol, and processes the converted challenge with the subscriber's secret key and authentication algorithm into an authentication response. The authentication response is converted to be compatible with the local authentication protocol, and transmitted to a local system communication unit. The challenge and response is then forwarded to the subscriber's home system for similar conversion and processing, and subscriber's response is compared against a home system generated response.Type: GrantFiled: July 29, 1994Date of Patent: July 16, 1996Assignee: Motorola, Inc.Inventors: Daniel P.

Patent number: 5410602Abstract: A method of secure key distribution in a communication system having a plurality of subscriber units and an infrastructure communication center is provided. A first subscriber unit sends a request to the infrastructure communication center for a secure communication link with a second subscriber unit. This request includes an encrypted session encryption key which was encrypted with a first subscriber registration key. The infrastructure communication center decrypts the encrypted session encryption key with the first subscriber registration key. Subsequently, the infrastructure communication center re-encrypts the session encryption key with a second subscriber registration key. This re-encrypted session encryption key is sent to the second subscriber unit. In an alternative method, the first subscriber unit and the infrastructure communication center a priori know a session key.Type: GrantFiled: September 27, 1993Date of Patent: April 25, 1995Assignee: Motorola, Inc.Inventors: Louis D.
