摘要： Disclosed is a method for encrypted communications. A first IPsec endpoint selects a security association (SA) from a security association database (SAD) by using a selector and then extracts an indexing parameter from SA. The indexing parameter is used to determine an active key location from a key storage database (KSD). Data packets are then encrypted using a key from the active key location. The first IPsec endpoint also forms a security parameter index (SPI) in a header of the data packet by using a keyID from the active key location and transmits the encrypted data packet with the header indicating the SPI to a second IPsec endpoint.

摘要： A radio is authenticated at the site and unique authentication information for the radio is stored at the site. A subsequent non-authentication message from the radio is received at the site and authentication information in the non-authentication message is identified. The unique authentication information stored at the site is compared with authentication information identified in the non-authentication message. If there is a match, the non-authentication message is authenticated with an authentication code included in the non-authentication message, wherein a predefined portion of the authentication code is obtained from at least one of a header portion or a data portion of the non-authentication message. Upon successfully completing authentication, the site repeats the non-authentication message towards destination radios indicated in non-authentication message.

摘要： A first communication unit receives an encrypted transmission from a second communication unit. The encrypted transmission was encrypted by the second communication unit using a first encryption key. The first communication unit compares the first encryption key to an encryption key associated with the first communication unit. If the first encryption key matches the encryption key associated with the first communication unit, the first communication unit processes the encrypted transmission further. If the first encryption key does not match the encryption key associated with the first communication unit, the first communication unit compares the first encryption key to an encryption key associated with the second communication unit. If the first encryption key matches the encryption key associated with the second communication unit, the first communication unit processes the encrypted transmission further; otherwise, the first communication unit does not process the encrypted transmission further.

摘要： Application service is provided for a subscriber unit (SU), employing a first protocol, in a communication network employing a second protocol. The method includes receiving a CAI OTAR message from the SU. The CAI OTAR message includes at least a key management message (KMM) and a CAI header of the SU. The method then includes determining that the first protocol employed by the SU is different from the second protocol associated with the communication network based on the received CAI OTAR message. The method further includes creating a key management message (KMM) preamble, associated with the second protocol, based on at least one of the CAI header and configuration information of the SU, and creating a data link independent (DLI) OTAR message associated with the second protocol. The DLI OTAR message includes the received KMM. The method finally includes encapsulating the DLI OTAR message with the created KMM preamble, and sending the encapsulated DLI OTAR message to a key management facility (KMF) unit operating at a second protocol.

摘要： A plurality of storage location numbers (“SLNs”), each having a cryptographic period, is received at a first device (100). A system cryptographic period is determined based on the SLN cryptographic periods. Prior to expiration of each system cryptographic period, if at least one SLN requires an updated, the first device sends updated key material for the at least one SLN. A second device (102) maintains first, second, and third keysets, wherein the first and second keysets comprise key material. The second device receives a message to make the first keyset active, and a second message for updating at least a portion of the key material in the second keyset with updated key material for at least one SLN. The second device makes the third keyset equivalent to the second keyset, updates the second keyset with the updated key material, and receives a third message to make the second keyset active.
