Abstract. This exposition paper suggests a new low-bandwidth publickey encryption paradigm. The construction turns a weak form of key privacy into message privacy as follows: let E...
We present a new proposal for a trapdoor one-way function, from which we derive public-key encryption and digital signatures. The security of the new construction is based on the ...
For most basic cryptographic tasks, such as public key encryption, digital signatures, authentication, key exchange, and many other more sophisticated tasks, ideal functionalities...
The Advanced Encryption Standard (AES) algorithm has become the default choice for various security services in numerous applications. In this paper we present an AES encryption h...
Consider a situation in which the transmission of encrypted messages is intercepted by an adversary who can later ask the sender to reveal the random choices and also the secret ...
