Keywords:
Information, cryptography, symmetric key, asymmetric key, Cipher text, Plain text, RSA AlgorithmAbstract
In today's information age, communication play a very important role which help in growth of new technologies. So security is an essential parameter to be considered. A mechanism is therefore needed to secure the information that is sent. The process of transforming the original information into an unreadable format is known as encryption. The process of again converting the unreadable format in to the original information is known as decryption. The study of both encryption and decryption is known as cryptography. This paper focuses on analysing different types of cryptography, concept of encryption and decryption, a brief introduction to cryptography techniques. If we are taking about security of information then following services come in mind i.e. Confidentiality (privacy of information), Authentication, Integrity (has not been altered) .This paper provides a detailed description of all these cryptography techniques and a public key cryptography algorithm RSA.
