چکیده

In the spirit of Diffie Hellman the concept of a protocol algebra is introduced using certain amalgamated free product of Braid group (B) and Thompson group (T ) together with a nilpotent subgroup H of index 2

Exactness of Reduced Amalgamated Free Product C {algebras

Some completely positive maps on reduced amalgamated free products of C∗–algebras are constructed, showing that every reduced amalgamated free product of exact C∗–algebras is exact. Consequently, every amalgamated free product of exact discrete groups is exact.

Amalgamated Free Product over Cartan Subalgebra

Amalgamated free products of von Neumann algebras were first used by S. Popa ([26]) to construct an irreducible inclusion of (non-AFD) type II1 factors with an arbitrary (admissible) Jones index. Further investigation in this direction was made by K. Dykema ([10]) and F. Rădulescu ([27, 29]) based on Voiculescu’s powerful machine ([40, 41, 44]), and F. Boca ([4]) discussed the Haagerup approxim...

On Embeddings of Full Amalgamated Free Product C∗–algebras

An embedding question for full (i.e. universal) amalgamated free products of C∗–algebras is raised, and solved in part. This is used to give a necessary and sufficient condition for the full amalgamated free product of finite dimensional C∗–algebras to be residually finite dimensional.

A Functional Cryptosystem Using a Group Action

Many public-key cryptosystems depend on the difficulty of solving a few specific problems such as finding the prime factorization of a composite number and the discrete logarithm problem. While the existing systems depending on the hardness of these problems are considered secure, there is still deep concern about the security of these systems. Shor [8]invented a fast algorithm for prime factor...

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
