Abstract:
Data deduplication technique has been widely
adopted by commercial cloud storage providers, which is both important and
necessary in dealing with the explosive growth of information. To further
protect the protection of users’ sensitive data within the outsourced storage
mode, many secure data de duplication schemes are designed and applied in
various scenarios. Among these schemes, secure and efficient re-encryption for
encrypted data de duplication attracted the eye of the many scholars, and lots
of solutions are designed to support dynamic ownership management. During
this paper, we target the re-encryption de duplication storage system and
show that the recently designed lightweight rekeying-aware encrypted de
duplication scheme is liable to an attack which we call it stub-reserved
attack. Furthermore, we propose a secure data de duplication scheme
with efficient re-encryption supported the convergent all-or-nothing transform
and randomly sampled bits from the Bloom filter. Because of the intrinsic
property of one-way hash function, our scheme can resist the
stub-reserved attack and guarantee the info privacy of information owners’
sensitive data. Moreover, rather than re-encrypting the complete
package, data owners are only required to re-encrypt a tiny low a part
of it through the CAONT, thereby effectively reducing the computation
overhead of the system. Finally, security analysis and experimental results
show that our scheme is secure and efficient in re-encryption.
EXISTING SYSTEM
In existing, the unquestionable SSE plans supporting
information dynamic update are altogether founded on deviated 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.
PROPOSED SYSTEM
In the proposed framework, we explore achieving
watchword search over interesting encoded cloud data with symmetric-key based
affirmation and propose a reasonable plot in this paper. In order to help the
capable check of dynamic data, we plan a novel Accumulative Authentication
Label reliant on the symmetric-key cryptography to deliver an
affirmation tag for each catchphrase.
