A Hybrid Approach for Data Encryption and Decryption
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Cryptography is the art of achieving security by encoding messages to make them non-readable. It is the technique for hiding data and information from unauthorized users. When we send simple message from one location to another then this message called plain text is visible to anybody. If we want to codify the message called cipher text so that no one can easily understand the meaning of message then we use cryptography techniques. Two basic components are – key (single or multiple) and algorithm. There are multiple algorithms available for encryption of secret data such as Data Encryption Standard, Advanced Encryption Standard, Rivest Shamir Adelson etc. The power of these algorithms is obtained from the keys used for encryption and decryption. In this work advanced & hybrid hill-cipher method is used for encryption and decryption of secret text. Instead of inverse matrix concept as used in traditional hill cipher method we use self repetitive matrix for advance hill cipher concept. It was given this name due to its repetition of itself after some steps of self multiplication.
