A Threshold ECC Based Intrusion Tolerant CA Scheme
Jinde Liu · Jisuanji gongcheng · 2004
The threshold cryptography provides a new approach to building intrusion tolerance applications. This paper introduces and analyzes ECC based ElGamal threshold digital signature and t-out-of-n secret sharing scheme. Based on those, an ECC-based zero-knowledge test approach and an ECC based threshold digital signature scheme are presented. Then the application of these techniques in intrusion tolerant CA is studied. By comparing with the CA scheme of ITTC project, performance analysis shows that this scheme is characterized by better security as well as higher efficiency.
