Notes on the Polyinstantiation Problem
Abstract
This memorandum collects together three working notes concerning the database security technique called polyinstantiation. The first is the position paper given for a panel session held at the Computer Security Foundations Workshop in June 1991. This outlines the relationship between confidentiality and integrity in general terms. The second gives the more specific position relating to the problems of polyinstantiation and how they are avoided with the insert low approach. The third note gives an example which illustrates the difference in attitude towards integrity between polyinstantiation and the insert low approaches.
