Authenticated two-party Diffie-Hellman key exchange allows two principals A and B, communicating over a public network, and each holding a pair of matching public/private keys to agree on a session key. Protocols designed to deal with this problem ensure A (B resp.)that no other principals aside from B (A resp.) can learn any information about this value. These protocols additionally often ensure A and B that their respective partner has actually computed the shared secret value. A natural extension to the above cryptographic protocol problem is to consider a pool of principals agreeing on a session key. Over the years several papers have extended the two-party Diffie-Hellman key exchange to the multi-party setting but no formal treatments were carried out till recently. In light of recent developments in the formalization of the authenticated two-party Diffie-Hellman key exchange we have in this thesis laid out the authenticated group Diffie-Hellman key exchange on firmer foundations.

Create and manage highly-secure Ipsec VPNs with IKEv2 and Cisco FlexVPN The IKEv2 protocol significantly improves VPN security, and Cisco s FlexVPN offers a unified paradigm and command line interface for taking full advantage of it. Simple and modular, FlexVPN relies extensively on tunnel interfaces while maximizing compatibility with legacy VPNs. Now, two Cisco network security experts offer a complete, easy-tounderstand, and practical introduction to IKEv2, modern IPsec VPNs, and FlexVPN. The authors explain each key concept, and then guide you through all facets of FlexVPN planning, deployment, migration, configuration, administration, troubleshooting, and optimization. You ll discover h...

Internet Key Exchange

High Quality Content by WIKIPEDIA articles! Internet Key Exchange (IKE or IKEv2) is the protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley protocol and ISAKMP. IKE uses X.509 certificates for authentication which are either pre-shared or distributed using DNS (preferably with DNSSEC), and a Diffie-Hellman key exchange to set up a shared session secret from which cryptographic keys are derived. In addition, a security policy for every peer which will connect must be manually maintained.

Abstract: "The Diffie-Hellman key exchange algorithm can be implemented using the group of points on an elliptic curve over the field F2n. A software version of this using n = 155 can be optimized to achieve computation rates that are significantly faster than non-elliptic curve versions with a similar level of security. The fast computation of reciprocals in F2n is the key to the highly efficient implementation described here."

A Novel Cryptographic Key-exchange Algorithm

The combination of advanced mathematical techniques with the enormous growth of the possibilities for automatic data-processing has resulted in very strong systems of cryptography, that is systems that are powerful, sophisticated, and virtually impregnable. Cryptographers cannot design cryptosystems that are guaranteed to have no weaknesses or that are impervious to unforeseeable methods of attack. Cryptosystems make it very difficult but not impossible for an attacker to determine the decoding key and also protect information resources at less cost than the value of the information that is being protected. This book is aimed at solving a real life situation of encryption which uses cryptographic techniques for secure communication. At the end, a mathematical algorithm will be developed to produce a Key Generation and Exchange situation which will comprise of private key and public key. The general objective of this book is to contribute to the general body of knowledge in the area of cryptography and to support classification of top secret information. The following security requirements will be met: - authentication, confidentiality, Integrity, non-repudiation.
