Identity-based cryptosystem has been the most active research area in cryptographic society. In such system, Public keys are some attribute of a user's identity, such as an email address, phone number, or social security number. ID-based cryptosystems have many advantages over PKI based cryptosystems in key distribution, but they also have an inherent drawback of key escrow problem, i.e. users' private keys are known to the key generation center (KGC). Therefore secure key issuing (SKI) is an
