摘要： Methods for establishing secure point-to-point communications in a trunked radio system include receiving, at a trunking controller, a request from a source endpoint for a traffic channel for confidential communications between the source endpoint and a destination endpoint using a shared unique first symmetric key. The trunking controller provides keying material related to the symmetric key over the secured control channel to at least one of the source or destination endpoints and assigns a traffic channel. Moreover, in response to the request, the controller assigns a traffic channel. The keying material enables the unique first symmetric key to be securely established between the source and destination endpoints.

摘要： A sending device generates 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 the set of symmetric encryption keys using the first KEK; encrypts the first KEK and the KMM encryption key using a first public key of a receiving device; and encrypts the second KMM using the KMM encryption key to generate an encrypted second KMM before sending 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.

摘要： A method and device is provided for dynamically maintaining and updating public key infrastructure (PKI) certificate path data across remote trusted domains to enable relying parties to efficiently authenticate other nodes in an autonomous ad-hoc network. A certificate path management unit (CPMU) monitors a list of sources for an occurrence of a life cycle event capable of altering an existing PKI certificate path data. Upon determining that the life cycle event has occurred, the CPMU calculates a new PKI certificate path data to account for the occurrence of the life cycle event and provides the new PKI certificate path data to at least one of a relying party in a local domain or a remote CPMU in a remote domain.

摘要： A method and device for distributing public key infrastructure (PKI) certificate path data enables relying nodes to efficiently authenticate other nodes in an autonomous ad-hoc network. The method includes compiling, at a certificate path management unit (CPMU), the PKI certificate path data (step 405). One or more available certificate paths are then determined at the CPMU for at least one relying node (step 410). Next, the PKI certificate path data are distributed by transmitting a certificate path data message from the CPMU to the at least one relying node (step 415). The certificate path data message includes information identifying one or more trusted certification authorities associated with the one or more available certificate paths.

摘要： A certificate issuer (210) can periodically request, receive, and store current server-based certificate validation protocol (SCVP) staples (225) for supported relying parties (205) from at least one server-based certificate validation protocol (SCVP) responder (215). The certificate issuer (210) can receive a contact initiation request (220) from one of the relying parties (205). Responsive to receiving the contact initiation request (220), the certificate issuer (210) can identify a current SCVP staple from the saved staples that is applicable to the relying party (205). The certificate issuer (210) can conveying a response to the contact initiation request (220) to the relying party (205). The response can comprise the identified SCVP staple and a public key infrastructure (PKI) certificate (230) of the certificate issuer. The SCVP staple can validate a certification path between the PKI certificate (230) and a different certificate trusted by the relying party (205).

摘要： A method and apparatus for distributing Certificate Revocation List (CRL) information in an ad hoc network are provided. Ad hoc nodes in an ad hoc network can each transmit one or more certificate revocation list advertisement message(s) (CRLAM(s)). Each CRLAM includes an issuer certification authority (CA) field that identifies a certification authority (CA) that issued a particular certificate revocation list (CRL), a certificate revocation list (CRL) sequence number field that specifies a number that specifies the version of the particular certificate revocation list (CRL) that was issued by the issuer certification authority (CA). Nodes that receive the CRLAMs can then use the CRL information provided in the CRLAM to determine whether to retrieve the particular certificate revocation list (CRL).
