Towards Achieving Keyword Search over Dynamic Encrypted Cloud Data with Symmetric-Key Based Verification

ABSTRACT:

Undeniable Searchable Symmetric Encryption, as a significant cloud security strategy, enables clients to recover the scrambled information from the cloud through catchphrases and confirm the legitimacy of the returned outcomes. Dynamic update for cloud information is one of the most well-known and essential prerequisites for information proprietors in such plots. Apparently, the existing unquestionable SSE plans supporting information dynamic update are altogether founded on a wry key cryptography confirmation, which includes tedious activities. The overhead of check may turn into a critical weight because of the sheer measure of cloud information. In this way, how to accomplish catchphrase search over dynamic encoded cloud information with effective confirmation is a basic unsolved issue. To address this issue, we investigate accomplishing watch word search over unique encoded cloud information with symmetric-key based check and propose a useful conspire in this paper. So as to help the productive confirmation of dynamic information, we structure a novel Accumulative Authentication Tag (AAT) in light of the symmetric-key cryptography to create a confirmation tag for every catch phrase. Profiting by the collection property of our structured AAT, the verification tag can be advantageously refreshed when dynamic tasks on cloud information happen. So as to accomplish productive information update, we plan another safe list made by a pursuit table ST based on the symmetrical rundown and a check list VL containing AATs. Attributable to the availability and the adaptability of ST, the update proficiency can be fundamentally improved. The security investigation furthermore, the exhibition assessment results demonstrate that the proposed plan is secure and effective.
