摘要：Data deduplication is a technique for decreasing the amount of storage space for an organization needsto save its data. In many organizations, the storage systems have duplicate copies of many pieces of data and itsinformation. For example, an equivalent file may be saved in several places by many users, or two or more files thataren't equivalent may still include much of the same data. Deduplication remove these extra copies by saving just onecopy of the data and changing the other copies with pointers that lead back to the original copy. In this paper firstattempt to conventionally address the problem of resolve dynamic and reliable key management in deduplication. In thebaseline approach each user holds a separate master key for encrypting the convergent keys and redistributes them tothe cloud. And we propose a method Deckey, a new construction in which users are not need to manage any keys ontheir own. Security analyses establish that Deckey is secure in terms of the exposition specified in the proposed securitymodel. As a proof of concept, we implement Deckey using the Ramp secret sharing scheme and determine that Deckeyacquire limited overhead on realistic environments.
