Abstract

An abstraction and some desirable properties of the PHT layer as defined in SAFER are identified. These properties lead to the construction of 3071 other structures which could be used as alternative PHT layers. Results of preliminary investigations carried out on these structures to ascertain their suitability as alternatives are briefly discussed, together with other possible uses and open problems.
