We use combinatorial methods and permutation groups to classify homogeneous boolean functions. The property of symmetry of a boolean function limits the size of the function’s cl...
A sensitive point in public key cryptography is how to protect the private key. We outline a method of protecting private keys using cryptographic camouflage. Specifically, we do ...
The growing use of mobile code in downloaded applications and servlets has increased interest in robust mechanisms for ensuring privacy and secrecy. Information flow control is in...
Two years ago [3] we began to study a R.I.S.C. approachfor smart card microprocessors. We reconsider this research to answer the question of the new technology of smart cards: the...
A basic function of all signatures, digital or not, is to express trust and authority, explicit or implied. This is especially the case with digital signatures used in certificates...
