The terminal A then sends an authentication request to the terminal B by providing an attribute certificate that matches the network identifier contained in the beacon.

Abstract: A method for assigning a global address to a node in an ad-hoc network is provided. A joining node to the ad-hoc network generates a local address using its MAC address. The joining node inquires of its one-hop nodes about whether they occupy a local address that is the same as the generated local address. When the joining node is informed that there are no nodes occupying the same local address, it generates a global address using the generated local address and a global prefix provided from neighbor nodes. The joining node inquires of an Internet gateway about whether the generated global address is currently used. When the joining node is informed that there are no nodes currently using the same global address, the joining node is assigned the generated global address. Further, the joining node and the Internet gateway communicate messages via a relay node using a tunneling.

Abstract: A secure mechanism for transparent key recovery for a user who has changed authentication information is disclosed. A password manager agent intercepts requests by a user to access secure resources that require user credentials. Upon detecting changed authentication information for the user, the password manager agent automatically regenerates the components of a cryptographic key associated with the user that was previously used to encrypt user credentials for the user and then destroyed. After regeneration of the original cryptographic key, the password manager agent uses the key to decrypt the user credentials necessary for the requested application. The regenerated key is then destroyed and the user credentials are re-encrypted by the password manager agent using a new cryptographic key associated with the user made up of multiple components.
