We propose a new security class, called plaintext-simulatability, defined over the public-key encryption schemes. The notion of plaintext simulatability (denoted PS) is similar to ...
ElGamal scheme has been the first encryption scheme based on discrete logarithm. One of its main advantage is that it is simple, natural and efficient, but also that its security ...
This paper presents a novel framework for the generic construction of hybrid encryption schemes which produces more efficient schemes than the ones known before. A previous framew...
Abstract. Semantic security against chosen-ciphertext attacks (INDCCA) is widely believed as the correct security level for public-key encryption scheme. On the other hand, it is o...
Token-controlled public key encryption (TCPKE) schemes, introduced in [1], offer many possibilities of application in financial or legal scenarios. Roughly speaking, in a TCPKE s...
