摘　　要：现有关于注册码(RC)软件保护方式的改进中缺乏对增强其抗截获欺骗能力的研究。针对两种常见的截获欺骗攻击模型,提出一种抗截获欺骗攻击的RC软件保护算法Anti-ISA RCSP,在不改变RC算法和验证算法的前提下,通过使用密钥协商和加密技术,提高现有RC软件保护的有效性。分析表明,在增加信息交互和时空需求代价下该算法可以解决现有RC保护手段的难题,其安全强度与密钥协商过程和加密算法的安全性相当。There is a lack of researchs about enhancing the ability to resist interception and deception during the improvement of the registration code based software protection method. This paper proposes a software protection algorithm using registration code(Anti-ISA RCSP) against two common interception and spoofing attack models. Under the premise of not changing the registration code algorithm and the verification algorithm, the effectiveness of the current software protection with registration code was improved with key agreement and encryption. The analysis shows that the proposed mechanism can solve the current problem of the software protection with the cost of increasing the information interaction and space-time requirements. The security strength was equivalent to the security of the key negotiation process and the encryption algorithm.
