Security is an important issue in digital data transmission and storage. The security can be provided by image encryption. Encryption is one of the ways to provide high security when images are transmitted over the network. Image encryption techniques scrambled the pixels of the image and decrease the correlation among the pixels, so that we will get lower correlation among the pixel and get th...

in a mobile ad hoc network, there are some features such as the ability to exploit multipath effect for information exchange with high reliability and low error rate. dealing with the aggressors and discovering the path in data transmission are of importance. approaching these goals ends in network promotion and efficiency. in this paper, the designed protocol is able to discover multipath fo...

We first propose the notion of universally anonymizable publickey encryption. Suppose that we have the encrypted data made with the same security parameter, and that these data do not satisfy the anonymity property. Consider the situation that we would like to transform these encrypted data to those with the anonymity property without decrypting these encrypted data. In this paper, in order to ...

• Different data storage encryption schemes, such as file/folder encryption and full-drive encryption (FDE). • SEDs as data protection tools, covering methods to manage encryption and SEDs, including management of these security features in concert with software on the host computer. • Industry and government protocols that ensure consistency and conformity of data security systems. These inclu...

Users are inclined to share sensitive data in a remote server if no strong security mechanism is in place. Searchable encryption satisfies the need of users to execute a search on encrypted data. Previous searchable encryption method such as “public key encryption with keyword search (PEKS)” restricted the data access to certain users, because only the assigned users were able to search on the ...
