ITBES:One Threshold and Identity Based Encryption-signature Scheme for WSN
Hui Wang · Journal of Nanjing University of Posts and Telecommunications · 2009
In order to improve the confidentiality of the private key generator(PKG)in identity-based encryption-signature(IBES)scheme,we improve the Xavier IBES scheme,and use(t,n)secret sharing scheme of threshold cryptography to split the master secret s among n peer to peer third PKGs.We apply the new IBES scheme in wireless sensor network,and discuss its efficiency and security in terms of complexity,storage requirement and security.Analysis shows that our scheme can efficiently improve the confidentiality of the PKG and the security of wireless sensor network.
