Data comparable encryption scheme based on cloud computing in Internet of things
摘要
Abstract
The previously proposed short comparable encryption (SCE) scheme can infer the plaintext relationship by comparing the ciphertexts relationship as well as ensuring data security in Internet of things. Unfortunately, it will incur high storage and computational burden during the process of comparing ciphertexts and generating tokens. To this end, an efficient short comparable encryption scheme called SCESW was proposed, which was utilizing the sliding window method with the same size window. Formal security analysis shows that the scheme can guarantee weak indistinguishability in standard model as well as data security and integrity. The experimental results demonstrate that the storage of the SCESW scheme is 1t ( 1)t> times shorter than that of the SCE scheme and the efficiency of the SCESW scheme is superior to that of the SCE scheme.关键词
