Implementation of a secure bridge in an Ethernet environment
F. Recacha, F. Rico, J.L. Melus · 1992
The implementation of a security system that caters to the needs of an operating network, the UPC NET, is presented. The security services that this system offers are confidentiality and authentication (origin authentication and data integrity) of data transmitted on the main segment of an extended Ethernet network. The system has been designed to specifically function in the extended Ethernet network of the Polytechnic University of Catalonia. The security system has the following characteristics: it provides cryptographic security services, it does not interfere with the operation of unprotected systems, and it supports transparent operations for protected systems.>
