摘要:

已有的短比较加密(SCE,short comparable encryption)方案能在确保物联网数据安全的前提下通过比较密文数据大小而推出明文数据大小。但 SCE 方案在密文比较以及生成标签的过程中会引入大量的计算和存储开销。为此,提出一种基于滑动窗口技术统一开窗的高效短比较加密(SCESW,short comparable encryption based on sliding window)方案。严格的安全分析表明,SCESW方案在标准模型下满足弱不可区分性且保障了数据的完整性和机密性。同时,实验性能分析表明,SCESW方案的存储开销是SCE方案的 1 t (t1)且效率高于SCE方案。

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 1 t (t1) times shorter than that of the SCE scheme and the efficiency of the SCESW scheme is superior to that of the SCE scheme.

Key words: short comparable encryption, sliding window, standard model, weak indistinguishability, integrity
