A Note on Secure Key Issuing in ID-based Cryptography

XU Chunxiang and ZHOU Junhui and QIN Zhiguang

Abstract

Most recently, Lee B. et al proposed a key issuing protocol for ID-based cryptography to solve the key escrow problem. However in this letter, we show that a malicious key generation center (KGC) can successfully attack the protocol to obtain users¡¯ private keys. This means that in the protocol, the key escrow problem isn¡¯t really removed.
