Cryptography in Cloud Computing

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