An Improved Scheme of LeeB Secure Key Issuing Protocol
To resolve user's key escrow problem of Lee B et al's protocol, this paper presents an improvement by an identity-password pair published for confirming user identity and analyzes its security and efficence.The improved scheme overcomes the disadvantages of LeeB et al.ṥ scheme and save at least 4n pairing and 2n Hash operations.
