摘要： Systems and methods that allow the formation and distribution of session keys amongst a dynamic group of users communicating over an unreliable, or lossy, network. The systems and methods according to this invention allow an intermediate session key contained in an intermediate key distribution broadcast to be determined by receiving a preceding key distribution broadcast that precedes the intermediate key distribution broadcast, the preceding key distribution broadcast including a first portion of the intermediate session key; receiving a subsequent key distribution broadcast that follows the intermediate key distribution broadcast, the subsequent key distribution broadcast including a second portion of the intermediate session key that is distinct from the first portion; and combining at least the first portion of the intermediate session key contained within the preceding key distribution broadcast and the second portion of the intermediate session key contained within the subsequent key distribution broadcast to obtain the intermediate session key.

摘要： A method and system for encrypting a first piece of information M to be sent by a sender [100] to a receiver [110] allows both sender and receiver to compute a secret message key using identity-based information and a bilinear map. In a one embodiment, the sender [100] computes an identity-based encryption key from an identifier ID associated with the receiver [110]. The identifier ID may include various types of information such as the receiver's e-mail address, a receiver credential, a message identifier, or a date. The sender uses a bilinear map and the encryption key to compute a secret message key gIDr, which is then used to encrypt a message M, producing ciphertext V to be sent from the sender [100] to the receiver [110] together with an element rP. An identity-based decryption key dID is computed by a private key generator [120] based on the ID associated with the receiver and a secret master key s. After obtaining the private decryption key from the key generator [120], the receiver [110] uses it together with the element rP and the bilinear map to compute the secret message key gIDr, which is then used to decrypt V and recover the original message M. According to one embodiment, the bilinear map is based on a Weil pairing or a Tate pairing defined on a subgroup of an elliptic curve. Also described are several applications of the techniques, including key revocation, credential management, and return receipt notification.
