In this paper, we describe: (i) how agents can protect information from other agents and (ii) how servers that support agent cooperation can help in this process. We show that agents' data security policies can be encoded through three structures called metaknowledge, history and agent security tables. We develop a framework that allows arbitrary metalanguages and history maintenance policies to be “plugged in”, and develop complexity results, including polynomial (efficiently computable) approximations.
