Public key cryptography is important for exchanging messages securely between two parties on the Internet. The RSA algorithm, a method of public key cryptography, was invented and has been the most popular encryption method to date. Ron Rivest, Adi Shamir, and Leonard Adleman invented the RSA algorithm in 1978 at Massachusetts Institute of Technology. They studied the Diffie-Hellman-Merkle key exchange algorithm, which used public key but didn’t employ digital signatures. They then began searching for a better practical mathematical function of public key cryptography. They worked on more than 40 candidates until they finally discovered a great algorithm that exactly fit the requirements for a convenient public key cryptography implementation. The RSA algorithm is one of the topics of modular arithmetic in number theory. Number theory, a branch of pure mathematics, is the study of properties of integers. This branch works with different classes of problems that have arisen naturally from the study of integers. It is divided into several fields depending on the methods used and the types of questions researched. Modular arithmetic is one of the fields of number theory. In modular arithmetic, numbers only go from zero up to a certain value, theShow MoreRelatedDiscuss How Management Theory and Practice Has Changed over Since the Early 1900’s1408 Words   |  6 Pageswant to satisfy the social relationships, respond to group pressures and search for personal fulfillment.
