A certificateless key-insulated signature Scheme

With the fast development of the Mobile Internet,an open challenge is to keep the users' private key from being leaked in the unsafe environment. The key-insulated signature scheme is one of the promising methods of reducing the risk of the private key leakage. An identity-based key-insulated signature scheme was proposed in Reference [8],which is proved to secure in the standard model. But identity-based cryptography exists a key escrow problem in the practical applications. To solve this problem,a certificateless key-insulated signature scheme was proposed. It not only keeps the traditional functions of key-insulated signature scheme but also solves the key escrow problem in identity-based key-insulated signatures.
