摘要/Abstract

摘要： 在移动社交网络中，为保证交友匹配过程中用户的隐私，提出多密钥混淆隐私保护方案.利用代理重加密技术，对用户密钥密文进行重新加密，实现了以扩充交友访问策略条件的交友匹配，并保证密文转换过程中用户的隐私不被泄露；利用随机密文组件加密技术，实现了对真实明文对应加密文件的信息隐藏，提高了攻击者的破解难度；利用数据摘要签名技术，解决了以往方案未考虑的多加密文件对应的文件解密问题.安全和实验分析表明，本文方案可以达到CPA（Chosen Plaintext Attack）安全，可以保证交友用户的隐私不被泄露，并且比既有的方案更有效.

关键词: 多密钥混淆, 代理重加密, 数据签名, 隐私保护

Abstract: In mobile social networks, in order to ensure the privacy of users in the process of friend matching, a privacy protection scheme for multiple keys is proposed. Proxy re-encryption technology is utilized to encrypt the user's key into ciphertext, expand friend matching access policy conditions and ensure no leakage of the ciphertext of user privacy during the process of transformation. The employed encryption technology of random ciphertext components can realize the hidden information of the plainntext, and improve the crack difficulty of the attacker. Multiple encrypted files decryption problem is solved by data signature technology, which are not considered by previous works. Security and experimental analysis show that this scheme can achieve CPA (Chosen Plaintext Attack) security, ensure the privacy of friend discovery, and that is more effective than existing solutions.

Key words: multi-key confusion, proxy re-encryption, data signature, privacy-preserving
