摘　　要：隐私保护是信息安全的重要研究方向,为了提高隐私保护能力,提出一种基于椭圆曲线同态加密的增强性个性化匿名隐私保护模型。采用K-匿名编码方法进行隐私保护信息的编码设计,构建加密密钥,结合分段线性混沌映射方法进行隐私保护模型的算术编码设计,采用椭圆曲线同态加密算法进行个性化匿名隐私保护增强设计,提高信息加密的深度,实现隐私保护优化。仿真结果表明,采用该方法进行隐私保护信息加密和隐私保护抗攻击能力较强,信息泄露的风险大大降低。Privacy protection is an important research direction of information security.In order to improve the privacy protection capability,an enhanced personalized anonymous privacy protection model based on elliptic curve homomorphic encryption is proposed.The K-anonymous encoding method is adopted to design the privacy protection information encoding and construct the encryption key.Combined with the piecewise linear chaotic mapping method,arithmetic coding of privacy protection model is designed.The elliptic curve homomorphic encryption algorithm is used for the enhanced design of personalized anonymous privacy protection to improve the depth of information encryption and achieve privacy protection optimization.The simulation results show that the method for privacy protection information encryption has a strong attack resistance capability and can reduce the risk of information leakage.
