An Approach to Information Security Policy Modeling for Enterprise Networksg complexity of network security systems (NSSs) there is a challenge to manage them in accordance with IS policies. Incorrect configurations of NSSs lead to outages and appearance of vulnerabilities in networks. Moreover, policy management is a time and resource consuming process, which takes signif

Introduction to Attribute Based Searchable Encryption and the senders decide on a policy. The policy is a function of these attributes expressed as a predicate and determines, among the users of the system, who is eligible to decrypt and search the ciphertext. Only members who own sufficient attributes to satisfy that policy can send the server a vali

Since PUFs are “noisy” functions responses generated by a certain PUF instantiation are error-prone and therefore highly sophisticated error correction is re

Enhancing Privacy with Quantum Networksany application scenarios. The fact that the security is implemented directly at the hardware level, and moreover, relies on the laws of physics instead of conjectured hardness assumptions, justifies the use of quantum security in many cases. Limitations include 100 km communication range and instal

In addition, a growing list of legislative requirements adds to the ongoing task of protecting digital files and information.

To overcome these problems, we propose a new cloud identity management model based on the federation between different cloud identity brokers. The

We present a bit-string quantum oblivious transfer protocol based on single-qubit rotations that can be implemented with current technology based on optics and whose security relies only on the laws of physics.
