Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...

Cryptography is a key element in establishing trust and enabling services the digital world. It represented ways that are not accessible to human users. Hence, humans left out security necessary modern communication protocols many services. A primitive or protocol should be defined reach goal. Beside introduction part this paper represents types of cryptography, algorithm cryptography technique...

Secure transmission of messages has been a major goal since ages, for which cryptography is used. Cryptography is a mathematical techniques used for secure communication. Classical cryptography is traditional means that comprises mathematical functions to restrict eavesdropping problem in communication. Quantum cryptography is a new approach towards secure communication which uses phenomenon of...
