Abstract
A scheme based on cryptography is proposed for access control in a system where hierarchy is represented by a partially ordered set (or poset). Straightforward implementation f the scheme requires users highly placed in the hierarchy to store a large number of cryptographic keys. A time-versus-storage trade-off is then described for addressing this key management problem.
