A subtyping 0 is entailed by a set of subtyping constraints C, written C j= 0, if every valuation (mapping of type variables to ground types) that satisfies C also satisfies 0. ...
A multi-signature scheme enables a group of signers to produce a compact, joint signature on a common document, and has many potential uses. However, existing schemes impose key s...
Studying floating point arithmetic, authors have shown that the implemented operations (addition, subtraction, multiplication, division and square root) can compute a result and a...
The Baldwin Effect is a very plausible, but unproven, biological theory concerning the power of learning to accelerate evolution. Simple computational models in the 1980’s gave...
For the two last decades, electronic authentication has been an important topic. The first applications were digital signatures to mimic handwritten signatures for digital document...
