Security and Persistence

This volume presents the proceedings of the International Workshop on Computer Architectures to Support Security and Persistence of Information, which was held in Bremen, West Germany, in May 1990. The papers provide state-of-the-art details of current research into topics including persistent architectures, security, capability-based addressing and operating systems. Persistent systems are systems which support the creation and manipulation of objects in a uniform manner, regardless of how long they persist. This is in direct contrast to conventional systems where temporary and permanent objects are handled by separate mechanisms. The workshop brought together researchers in the areas of persistence and security to discuss issues related to architectural support for security and, as a result, capability-based protection schemes receive considerable attention. The implications of these architectures for software, in particular operating systems and databases, is the topic of several of the papers.
