摘　　要：为了降低数字化档案信息泄露和非法访问概率,确保密钥在传输和使用过程中不被泄露或篡改,降低冗余信息的干扰,提升信息安全性,提出一种基于身份认证的数字化档案敏感信息加密算法。通过基于椭圆曲线的身份认证确保只有合法身份认证的用户才能访问敏感信息,使用Bloom filter方法对合法用户访问的敏感信息中的冗余数据实施处理,减少不必要的信息量,利用混沌序列加密方法对处理后的敏感信息实施加密,生成具有高随机性和复杂性的混沌密钥,增加敏感信息破解的难度,确保数据的安全性。实验结果表明,所提算法能够有效地保护数字化档案中的敏感信息,防止未经授权的访问和泄露,具有较高的加密安全性。In order to reduce the probability of information leakage and ilegal access to digital archives,ensure that the key will not be leaked or tampered during transmission and use,reduce the interference of redundant information,and improve information security,an encryption algorithm for sensitive information of digital archives based on identity authentication is proposed.Through the identity authentication based on elliptic curve,it is ensured that only users with legal identity authentication can access sensitive information.The bloom filter method is used to process redundant data in sensitive information accessed by legal users,reducing unnecessary information.The chaotic sequence encryption method is used to encrypt the processed sensitive information,generating chaotic keys with high randomness and complexity,increasing the dificulty of cracking sensitive information and ensuring data security.The experimental results show that the proposed algorithm can effectively protect sensitive information in digital archives,prevent unauthorized access and disclosure,and has high encryption security.
