We define seal, an untyped call-by-value -calculus with primitives for protecting abstract data by sealing, and develop a bisimulation proof method that is sound and complete with...
The indistinguishability of two pieces of data (or two lists of pieces of data) can be represented formally in terms of a relation called static equivalence. Static equivalence dep...
