Double Layer Encoded Encrypted Data on Multicarrier Channel

Private Key based query on encrypted data

Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...

Computing on Encrypted Data

Encryption secures our stored data but seems to make it inert. Can we process encrypted data without having to decrypt it first? Answers to this fundamental question give rise to a wide variety of applications. Here, we explore this question in a number of settings, focusing on how interaction and secure hardware can help us compute on encrypted data, and what can be done if we have neither int...

Cross-Layer Designs of Multicarrier

− We study the performance of Non-Collision Packet Reservation Multiple Access (NC-PRMA) scheme as a MAC protocol for powerline communication networks. A PHY-MAC cross layer design is considered in order to provide Quality of Service (QoS) guarantees for integrated voice, data and video services. System performance is evaluated via simulations in terms of packet dropping probability and mean ac...

Fuzzy retrieval of encrypted data by multi-purpose data-structures

The growing amount of information that has arisen from emerging technologies has caused organizations to face challenges in maintaining and managing their information. Expanding hardware, human resources, outsourcing data management, and maintenance an external organization in the form of cloud storage services, are two common approaches to overcome these challenges; The first approach costs of...
