Certificateless Puklic Key Encryption With Equality Test of Supporting Keyword Search

摘要: 公钥加密等值测试(PKEET)可以实现云环境下不同公钥加密数据之间的密文等值比较，即不对密文解密的情况下测试两个密文对应的明文是否一致。但是，密文等值测试加密不提供关键字密文搜索功能。已有密文等值测试加密方案直接以消息生成陷门作为等值测试的凭证，测试的准确度不高，搜索效率较低。针对此问题，该文首先提出了支持关键字搜索的无证书密文等值测试加密(CLEETS)方案。方案通过关键字检索判断是否包含自己需要的信息，根据判断结果选择执行等值测试，从而避免无效测试。然后，在随机预言机模型下证明该方案满足适应性选择关键词不可区分性。最后，对方案进行功能和效率对比。对比结果表明，该文方案的计算代价略高，但是方案在密文等值测试加密中实现了关键字的检索功能，弥补了效率低的不足。Abstract: Public Key Encryption with Equality Test (PKEET) is an important method to achieve the equality test of ciphertexts which are generated by the different public key aiming to the same plaintext in cloud environment. In other words, it can tests the plaintext corresponding to the two ciphertext’s equivalence without decrypting the ciphertext, but does not supply the searchable function. Nowadays, the existing PKEET scheme takes directly the message to generate a trapdoor as the proof of equality test, which has low test accuracy and search efficiency. To solve the above problems, a certificateless public key encryption with equality test scheme supporting keyword search (CertificateLess Equality test EncrypTion with keyword Search, CLEETS) is proposed. The scheme determines whether it contains information needed by the user through the keyword search, then performs the equality test according to the search result, which can avoid invalid test. Then, it is proved that the scheme satisfies the indistinguishability of adaptive selection of keywords under the random oracle model. Finally, the comparison analyses of function and efficiency are performed. The results indicate the computation cost of CLEETS scheme is less efficient. Fortunately, it can realizes the function of keyword search in encryption with equality test, which can remedies the inefficiency.
