A New Circle based Symmetric key Encryption Technique for Text Data

Cryptography helps to send data from a sender to a receiver by providing confidentiality and integrity and it is carried out in two different phases – encryption and decryption. So many cryptographic algorithms are proposed for encryption and decryption process. All these algorithms come under either symmetric key cryptography or asymmetric key cryptography. A lot of research is going on these cryptographic algorithms and different approaches have been applied on them. Among all, geometrical approach is one of the most prominent cryptographic techniques. The proposed chakra based Text crypto system is based on chakra symmetric key encryption algorithm [1]. Here the encryption process is applied on Text data of different extensions which is considered as plain text and the corresponding cipher text is generated by the principle of circle generation and rotation. It works with less computational complexity and more confidentiality.
