A framework for IPSec functional architecture.

In today\u27s network, various stand-alone security services and/or proxies are used to provide different security services. These individual security systems implementing one single security function cannot address security needs of evolving networks that require secure protocol such as IPSec. In this paper, we provide a framework for implementing IPSec security functions in a well structured functional architecture. The proposed architecture is modular and allows for composing software applications from products commercially available and developed by different suppliers to implement the entire security requirements of IPSec protocol. In addition the proposed architecture is robust in the sense that it supports open standards and interfaces, and implements security functions of IPSec as an integrated solution under a unified security management system.Dept. of Electrical and Computer Engineering.

AES Key Agility Issues in High-Speed IPsec Implementations

Some high-speed IPsec hardware systems need to support many thousands of security associations. The cost of switching among different encryption keys can dramatically affect throughput, particularly for the very common case of small packets. Three of the AES finalists (Rijndael, Serpent, and Twofish) provide very high key agility, as is required for such applications. The other two candidates (MARS, RC6) exhibit low key agility and may not be appropriate for use in such equipment

A Cryptographic Tour of the IPsec Standards

In this article, we provide an overview of cryptography and cryptographic key management as they are specified in IPsec, a popular suite of standards for providing communications security and network access control for Internet communications. We focus on the latest generation of the IPsec standards, recently published as Request for Comments 4301–4309 by the Internet Engineering Task Force, and how they have evolved from earlier versions of the standards

An Overview of Cryptography (Updated Version, 3 March 2016)

There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography...While cryptography is necessary for secure communications, it is not by itself sufficient. This paper describes the first of many steps necessary for better security in any number of situations. A much shorter, edited version of this paper appears in the 1999 edition of Handbook on Local Area Networks published by Auerbach in September 1998
