A Survey of Secure Multi-Domain Distributed Architectures

Security in a modern distributed computing system is becoming more and more important. Users want to securely access remote resources both in the local domain and across multi-domains. Recently, a number of new architectures for securing a distributed system have been proposed. This paper outlines the issues important to securing a multi-domain distributed system and surveys a number of secure distributed architectures. The architectures surveyed include SESAME (Secure European System For Applications in a Multivendor Environment), Kerberos, Yaksha, KryptoKnight, DCE (Distributed Computing Environment), and DSSA (Distributed System Security Architecture). For each architecture an outline of its strengths and limitations is included.
