摘要： A challenge manipulation and restoration capability is provided for use during network authentication. A mobile device (MD) and a subscriber server (SS) each have provisioned therein a binding key (B-KEY) that is associated with a subscriber identity of a network authentication module (NAM) of the MD. The SS obtains an authentication vector (AV) in response to a request from a Radio Access Network (RAN) when the MD attempts to attach to the RAN. The AV includes an original authentication challenge parameter (ACP). The SS encrypts the original ACP based on its B-KEY, and updates the AV by replacing the original ACP with the encrypted ACP. The MD receives the encrypted ACP, and decrypts the encrypted ACP based on its B-KEY to recover the original ACP. The MD provides the original ACP to the NAM for use in computing an authentication response for validation by the RAN.

摘要： A method for securing at least one message transferred in a communication system from a first computing device to a second computing device in a peer-to-peer manner. At the first computing device, an identity based authenticated key exchange session is established with a third computing device operating as a peer authenticator. The identity based authenticated key exchange session has an identity based authenticated session key associated therewith. The first computing device obtains from the third computing device a random key component of the second computing device, wherein the random key component of the second computing device is encrypted by the third computing device using the identity based authenticated session key prior to sending the random key component of the second computing device to the first computing device. A peer-to-peer messaging key is computed at the first computing device using the random key component of the second computing device.

摘要： There can be problems with the security of social networking communications. For example, there may be occasions when a number of friends wish to communicate securely through a social network infrastructure, such that non-trusted 3rd-party entities, such as a Social Network Operator or host that provides the application infrastructure, does not overhear the communication. In response to the above problems, embodiments presented propose a set of innovative, lightweight solutions, considering that in certain scenarios the Social Network Operator may not be a trusted entity. Embodiments of the present invention are directed to methods and apparatuses for secure information sharing in social networks using random keys.
