Abstract: | It is important to ensure the private key secure in cryptosystem. To reduce the underlying danger caused by the private key
leakage, Dodis et al. (2003) introduced the notion of key-insulated security. To handle the private key leakage problems in
certificateless signature schemes, we propose a new certificateless strong key-insulated signature scheme. Our scheme has
two desirable properties. First, its security can be proved without utilizing the random oracle model. Second, it solves the
key escrow problems in identity-based key-insulated signatures (IBKISs). |
