“…In a traditional KP-ABE method, the characteristics of specified attributes have been treated at the same level. In real environment applications, each attribute has a different weight according to its significance [1]. In present days, web technology has become faster and stronger.…”

The cryptography is a method of converting plan text data into non-readable form so that the data can be protected from hacking. There are two main techniques used for converting data into other form; Transposition technique and Substitution technique. The main objective of this paper is to explain some classical cipher techniques along with its solution. In this paper, two implemented cipher technique 'Two Way Cipher Transposition' and 'Disorder Cipher Transpositions' have been studied and implemented over original message. The analysis of these two implemented techniques found that these techniques are more strong and convenient than the previous transposition techniques.

“…In [29], with the case of the personal health record, Li et al realized the security and scalable and fine-grained access control, supporting the modification of access policies and revocation of attributes. Liu et al assumed that each attribute had different importance and constructed schemes that supported the access structure with different weights in CP-ABE [30] and KP-ABE [31]. Liu et al added traceability to an existing expressive, efficient, and secure CP-ABE scheme without weakening its security, and change in the length of Mobile Information Systems 3 the ciphertext and decryption key does not cause too much overhead [32].…”

VCC (Vehicular Cloud Computing) is an emerging and promising paradigm, due to its significance in traffic management and road safety. However, it is difficult to maintain both data security and system efficiency in Vehicular Cloud, because the traffic and vehicular related data is large and complicated. In this paper, we propose a conditional ciphertext-policy attribute-based encryption (C-CP-ABE) scheme to solve this problem. Comparing with CP-ABE, this scheme enables data owner to add extra access trees and the corresponding conditions. Experimental analysis shows that our system brings a trivial amount of storage overhead and a lower amount of computation compared with CP-ABE.

“…A consumer can decrypt a ciphertext if and only if his/her secret key has a match with the ciphertext. Weighted attribute-based encryption [16][17][18][19][20][21] is a variant of ABE. It assigns different weights to attributes according to their importance.…”

With the rapid development of cloud computing, it is playing an increasingly important role in data sharing. Meanwhile, attribute-based encryption (ABE) has been an effective way to share data securely in cloud computing. In real circumstances, there is often a mutual access sub-policy in different providers’ access policies, and the significance of each attribute is usual diverse. In this paper, a secure and efficient data-sharing scheme in cloud computing, which is called unified ciphertext-policy weighted attribute-based encryption (UCP-WABE), is proposed. The weighted attribute authority assigns weights to attributes depending on their importance. The mutual information extractor extracts the mutual access sub-policy and generates the mutual information. Thus, UCP-WABE lowers the total encryption time cost of multiple providers. We prove that UCP-WABE is selectively secure on the basis of the security of ciphertext-policy weighted attribute-based encryption (CP-WABE). Additionally, the results of the implementation shows that UCP-WABE is efficient in terms of time.
