Use the Singular Values Decomposition in the Text Encryption with Encryption Key Is Real Number
Cryptography is the art of achieving security by converting the message to unreadable message. This paper encrypted text based on SVD algorithm. In the first stage specific numbers suggested for each letters and punctuation characters (or using the ASCII code), and these numbers used instead of each character. The sender and receiver will agree for random real number as a key to encrypt the text. By using positive and negative key we create two new matrices which process with SVD algorithm. Decryption is the inverse process of encryption. The encrypted text tested by using many measures and gives promised results.
