摘 要: 入侵容忍是网络安全中的一种新方法,该方法保证系统在遭受攻击的情况下信息的机密性、完整性和可用性.本文基于安全的椭圆曲线,结合门限体制、可验证秘密共享体制以及主动秘密共享方案,给出一种新的入侵容忍签字方案.新方案在签名时可以避免密钥重构,防止了密钥的泄漏. Intrusion Tolerance is a new approach in network security, which is designed so that any intrusion into a part of the system will not endanger the data's confidentiality,integrity and availability. A secure elliptic curve,combined threshold scheme,verifiable secret share scheme with proactive secret share scheme is selected to make sure security requirement. The intrusion tolerant signature scheme is presented based on ECC to avoid reconstructing secret and prevent leak of secret.
