摘要： A system including a temporal key module, a nonce module, a security module, and an encryption module. The temporal key module generates a first temporal key used to encrypt a plurality of packets. The nonce module generates a nonce for each packet encrypted based on the first temporal key. Each nonce includes a packet number that is different than packet numbers associated with other nonces generated by the nonce module. The packet number is greater than N bits in length, where N is an integer greater than 40. The security module determines when the packet number included in the nonce generated by the nonce module is greater than or equal to a predetermined threshold. The encryption module encrypts more than 2(N−1) packets using the first temporal key and the nonces without reusing a value of the packet number.
