An intrusion-resilient signature scheme based on ECDLP
Chenghua Li, XingBo Peng · 2010
Intrusion-resilient signature schemes guarantee stronger security than forward-secure and key-insulated signature scheme. A novel intrusion-resilient signature scheme based on Elliptic Curve Discrete Logarithm Problem (ECDLP) is proposed. The proposed scheme combines the advantages of Elliptic Curve Digital Signature Algorithm (ECDSA) and intrusion-resilient security mechanism. It achieves mitigating the harmful effects caused by key exposure while preserving the efficiency and interoperability of ECDSA.
