Code-based cryptography is often viewed as an interesting “Post-Quantum” alternative to the classical number theory cryptography. Unlike many other such alternatives, it has th...
The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in p...
The classical role of a firewall consists in protecting a computer network against attacks from the outside world, especially the Internet. Firewalls are often expensive, hard to c...

Abstract An encryption scheme is non-malleable if the adversary cannot transform a ciphertext into one of a related message under the given public key. Although providing a very st...
— While many protocols for sensor network security provide confidentiality for the content of messages, contextual information usually remains exposed. Such information can be c...
