Identity-based threshold key issuing protocol for Ad Hoc networks
Liming Fang · Engineering Journal of Wuhan University · 2007
Key issuing protocol is an important issue in identity-based cryptography. At present there are some key issuing protocols in ID-based cryptography;but those protocols are not applied due to the properties of the Ad Hoc networks.An identity-based threshold key issuing protocol is proposed for Ad Hoc networks, in which secret sharing is deployed to realize the distributed generation of the system's private key;and it makes use of the blind signature to ensure the secure issuing of the private keys of nodes in public channel. In proposed protocol, neither node can impersonate the users to obtain the private keys and is secure against replay, man-in-the-middle and insider attacks;and it suits for Ad Hoc networks.
