    Abstract: A secure communication system (100) that is capable of over-the-air-rekeying (OTAR) employs a key management controller (108) to provide secure communications for a requested call. The key management controller determines (403) when the requested call has been initiated and identifies (405) some of the plurality of radios as being members of the requested call. A call key is then transmitted (409) to the members of the requested call where it is used (514) for the duration of the requested call. In this manner, secure communications between the members of the requested call is provided.

    Abstract: A method includes receiving an authentication request from a mobile station (401) and determining whether to forward the request to an authentication agent. When it is determined to forward the request, the request is forwarded to the authentication agent (107). A random number and a random seed are received from the authentication agent (107). The random number and the random seed are forwarded to the mobile station (401). A response to the random number and the random seed from the mobile station (401) is received and forwarded to the authentication agent (107). The authentication agent (107) compares the response with an expected response. When the authentication agent (107) authenticates the mobile station (401), a derived cipher key is received from the authentication agent (107).

    Abstract: Roaming encryption key rekeying apparatus and method comprising a first system key management facility that communicates to a communication unit roaming information is disclosed. The roaming information is encrypted using a first encryption scheme that is decipherable by the communication unit. Further, the first system key management facility communicates to a second system key management facility the roaming information. In this communication, the roaming information is encrypted as a function of a second encryption scheme that is decipherable by the second system key management facility.
