摘　　要：随着大数据、云计算技术的发展和普及,大量数据向云端迁移,其中含有大量敏感数据。针对云存储中存在的数据泄露和隐私安全问题,提出了一个手机通讯录安全云备份系统,使用一种基于三维无简并离散超混沌数据加密算法,对手机通讯录进行加密备份,然后以密文的形式上传存储在云端,在下载时进行解密,恢复数据。与一般的简并超混沌加密算法相比,该加密方法改进了安全性能,可以防止数据在传输过程以及云端泄露隐私,保证敏感数据在云端的安全。With the development and popularization of big data and cloud computing technologies,individuals,companies,and countries have migrated large amounts of data to the cloud,including a large amount of sensitive data.Aiming at data leakage and privacy security problems in cloud storage,a secure cloud backup system for mobile phone address book is proposed.This system uses a 3D simplified and discrete hyperchaotic data encryption algorithm to encrypt and backup the mobile phone address books.The personal data of user is encrypted and then uploaded to the cloud with the form of ciphertext.The encrypted data is decrypted when downloading.Compared with the existing simple and general superchaotic encryption algorithm,the security performance is improved by using 3D non-degenerate and discrete superchaotic encryption.Thus,the system can prevent the privacy data leakage in the process of transmission and in the cloud,which can ensure the security of the sensitive data.
