An Efficient Massive Evidence Storage and Retrieval Scheme in Encrypted Database
Ruoqing Zhang, Zehui Li, Zichen Li, Yatao Yang · 2013
In this paper, the problem is described which of storing massive digital evidence and preventing potential information leaks in forensics. The strategy of cloud encrypted database is therefore to be proposed. Existing encrypted database frameworks and solutions do not provide a satisfactory result to solve the problem. They either cause potential information leaks or have unacceptable data redundancy. We propose an efficient encrypted database model adopting initialization vector transfer and numerical order replacement. Experimental results show that the ciphertext retrieval speed can be significantly matched with what of plaintext.
