Method and system for deriving an encryption key using joint randomness not shared by others |
摘要 |
The present invention is related to a method and system for deriving an encryption key using joint randomness not shared by others (JRNSO). Communicating entities generate JRNSO bits from a channel impulse response (CIR) estimate and the JRNSO bits are used in generation of an encryption key. The authentication type may be IEEE 802.1x or a pre-shared key system. In an IEEE 802.1x system, a master key, a pairwise master key or a pairwise transient key may be generated using the JRNSO bits. The encryption key may be generated by using a Diffie-Hellman key derivation algorithm.
