摘要： A portable electronic device is operable as a portable certification authority. The portable electronic device stores a pair of keys of a public key infrastructure, issued by a parent certification authority and generates a certificate dependent upon the pair of keys. The private key and corresponding public key certificate are transmitted to a network device of a second agency to allow the device to be authenticated by any node of the network of the first agency that posses anchor information of the parent certification authority. This enables the device of the second agency to be authenticated by a network node of the first agency.

摘要： An ad hoc network includes a first node, a second node, and a third node. The first node and second node share a first shared secret key, and the first node and third node share a second shared secret key. The second node and third node share a temporal key. The first node generates a unique key, encrypts the unique key with a first shared secret key to generate a first encrypted unique key and transmits the first encrypted unique key to the second node. The first node encrypts the unique key with a second shared secret key to generate a second encrypted unique key and transmits the second encrypted unique key to the third node. To establish the temporal key, the second node decrypts the first encrypted unique key and the third node decrypts the second encrypted unique key thereby each generating the unique key.

摘要： A method and system for mutually authenticating a first node and a second node operating in a wireless communication network enables mutual authentication when the first node and the second node are unable to directly authenticate each other. The method includes identifying, at the first node, a third node that can authenticate both the first node and the second node (step 215). Authentication data for authenticating the first node with the third node is then transmitted from the first node to the third node (step 220). Keying material that is received from the third node is then processed at the first node (step 225). A shared secret mutual authentication protocol is then processed, whereby the first node and the second node are mutually authenticated by proving that they each have authenticated with the third node and each have the keying material (step 230).

摘要： A truncated message digest of length L bits is generated from a message by preprocessing the message dependent upon the value L to obtain a modified message. As part of the preprocessing, the message is lengthened by insertion of additional values. A full length message digest is generated from the modified message and the truncated message digest is obtained by truncating the full length message digest to L bits. This approach results in truncated message digests that are secure and provide a large range of truncation options.

摘要： A system and method of providing security in a wireless network is provided. A plurality of pre-shared keys is created. Each pre-shared key provides access to the wireless network. A list of the plurality of pre-shared keys is transmitted to an access point device in the wireless network so that the access point device can authenticate a station attempting to access the network by performing an analysis with the list of the plurality of pre-shared keys.
