Design Of A Secure B2B Environment
Design Of A Secure B2B Environment

Summary/Abstract: This paper presents application of the topological physical space and software logical layered approaches to design of distributed business to business (B2B) systems. Being a tutorial in nature, this paper is stressing explicitly strict, almost formal, technical terminology, which has been loosely used in relevant technical literature. In the introductory part we discuss general e-business sytem design issues, focusing on B2B systems with built in security components necessary for secure business transactions. Special attention is devoted to the integration of individual systems of B2B business partners without any additional modification or redesign of the original existing local business automation software versions.We insist on B2B designs without any existing software alterations caused by security problems. With such a design approach, security problems become totally transparent to the original designers of the business partner’s local systems and future users of B2B systems Special attention is devoted to the problems of possible drastic asymmetry of B2B business partners, where one partner could be too small and the other too large, resulting in degeneration of the B2B to customer to business or C2B system. Finally, we present design alternatives with different distributions of cryptographic modules in space, across the network topology and logically, along the stack of software layers and protocols.
