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: The method generally includes the steps of receiving (201) a message (100) comprising a message indicator (101) and a plurality of encrypted blocks (103 through 111). When at least one block of the plurality of encrypted blocks is received with error, a second message is transmitted (215), which second message requests a retransmission of the at least one block. Upon receiving the retransmission of the at least one block without error, a keystream is generated (219) from the message indicator and the at least one block is decrypted using the keystream.

Abstract: A sending device generates (204) a first and a second KMM, wherein the first KMM includes a first KEK and a KMM encryption key, and the second KMM includes a set of symmetric encryption keys. The sending device further encrypts (206) the set of symmetric encryption keys using the first KEK; encrypts (208) the first KEK and the KMM encryption key using a first public key of a receiving device; and encrypts (210) the second KMM using the KMM encryption key to generate an encrypted second KMM before sending (218) the first KMM and the encrypted second KMM to the receiving device. The receiving device decrypts the first KEK and the KMM encryption key using a first private key that corresponds to the first public key; and decrypts the encrypted second KMM using the KMM encryption key to obtain the encrypted set of symmetric keys.

Abstract: A method of decrypting retransmitted parts of a message includes receiving (201) a message comprising encryption synchronization and a plurality of encrypted blocks. Until a first block of the plurality of encrypted blocks is received with error, a first keystream is generated (205) from the encryption synchronization and at least one of the plurality of encrypted blocks, and, using the first keystream, the plurality of encrypted blocks, received without error before the first block of the plurality of encrypted blocks is received with error, is decrypted (207). A priming block is determined (211) from the message. When the first block of the plurality of encrypted blocks is received with error, a second message is transmitted (219) requesting a retransmission of the first block. Upon receiving the retransmission of the first block without error, a second keystream is generated (223) from the priming block and the retransmission of the first block and decrypting the retransmission of the first block is decrypted (225) using the second keystream.
