Abstract

Abstract: Traditional distributed system services that provide guarantees related to confidentiality, integrity, and authenticity enhance security, but are not survivable since each attribute is implemented by a single method. This paper advocates the use of redundancy to increase survivability by using multiple methods to implement each security attribute and doing so in ways that can vary unpredictably. As a concrete example, the design and implementation of a highly configurable secure communication service called SecComm are presented. The service has been implemented using Cactus, a system for building highly configurable protocols and services for distributed systems. Initial performance results for a prototype implementation on Linux are also given.
