Improved identity-based key-insulation signature scheme
对一种基于身份的强密钥绝缘签名方案的改进

A new identity-based strong key-insulated signature scheme without key escrow was proposed. Our proposed scheme not only solved the problem of key update but also the problem of key escrow that was ignored in the proposed scheme by Weng et al. The computational cost of this scheme during the "Verify" phase was also lower.
