چکیده

NULL is a block cipher the origins of which appear to be lost in antiquity. Despite rumors that the National Security Agency suppressed publication of this algorithm, there is no evidence of such action on their part. Rather, recent archaeological evidence suggests that the NULL algorithm was developed in Roman times, as an exportable alternative to Ceaser ciphers. However, because Roman numerals lack a symbol for zero, written records of the algorithm’s development were lost to historians for over two millennia.

RFC 5879 Heuristics for Detecting ESP - NULL

This document describes a set of heuristics for distinguishing IPsec ESP-NULL (Encapsulating Security Payload without encryption) packets from encrypted ESP packets. These heuristics can be used on intermediate devices, like traffic analyzers, and deep-inspection engines, to quickly decide whether or not a given packet flow is encrypted, i.e., whether or not it can be inspected. Use of these he...

Hardware Implementation of Dynamic S-BOX to Use in AES Cryptosystem

One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...

RFC 6476 MAC Encryption in CMS

This document specifies the conventions for using Message Authentication Code (MAC) encryption with the Cryptographic Message Syntax (CMS) authenticated-enveloped-data content type. This mirrors the use of a MAC combined with an encryption algorithm that’s already employed in IPsec, Secure Socket Layer / Transport Layer Security (SSL/TLS) and Secure SHell (SSH), which is widely supported in exi...

A Novel Image Encryption Model Based on Hybridization of Genetic Algorithm, Chaos Theory and Lattice Map

Encryption is an important issue in information security which is usually provided using a reversible mathematical model. Digital image as a most frequently used digital product needs special encryption algorithms. This paper presents a new encryption algorithm high security for digital gray images using genetic algorithm and Lattice Map function. At the first the initial value of Logistic Map ...

A Study of the Relative Costs of Network Security Protocols

While the benefits of using IPsec to solve a significant number of network security problems are well known and its adoption is gaining ground, very little is known about the communication overhead that it introduces. Quantifying this overhead will make users aware of the price of the added security, and will assist them in making well-informed IPsec deployment decisions. In this paper, we inve...
