基于混沌映射的隐私数据库自适应加密方法

Adaptive encryption method for privacy database based on chaos mapping

通过对隐私数据库的加密,可以确保数据在传输中不被篡改,保障数据安全。为此,提出基于混沌映射的隐私数据库自适应加密方法。在混沌映射条件下,实施明文信息与密文信息的置换,并在此基础上,建立密文空间,实现基于混沌映射的加密规则定义。利用完成初始化的隐私数据样本,在分层添加密文模板的同时,实现对加密信息的自适应解算,完成基于混沌映射的隐私数据库自适应加密方法的设计。实验结果表明,基于混沌映射的加密后,敏感性数据仅能被特定加密主机识别,显著减少信息篡改的风险,确保数据在隐私数据库中的安全存储。

By encrypting the privacy database,it can ensure that data is not tampered with during transmission and ensure data security.To this end,a privacy database adaptive encryption method based on chaotic mapping is proposed.Under the condition of chaotic mapping,permutation of plaintext information and ciphertext information is implemented,and based on this,a ciphertext space is established to define encryption rules based on chaotic mapping.Using the initialized private data samples,while adding ciphertext templates in layers,adaptive computation of encrypted information is achieved,and the design of an adaptive encryption method for privacy databases based on chaotic mapping is completed.The experimental results show that after encryption based on chaotic mapping,sensitive data can only be recognized by specific encryption hosts,significantly reducing the risk of information tampering and ensuring the secure storage of data in privacy databases.
