A Review on Outsourced Attribute-based Encryption Technique for Secure Data Storage

摘要

In the current world, more confidential information on untrusted repositories is maintained such that it is important to encrypt data on these pages. New encryption methods are being developed and improved from time to time. "AES" (Advanced Encryption Standard) is one such encryption protecting machine, which offers fine grained access control. Think of the ABE as a Cipher Scheme. However, the expressive mode of the ABE method can be problematic for the ABE in interpreting the key clarification and result in a low computational performance for the key problem and key decryption. To fix this issue, several outsourced versions of the Chinese Abacus (a concrete plane not made of beads on sticks), were built to improve the reliability of its use. This paper describes the various methods suggested and contrasts them, illustrating the benefits with the drawbacks.
