A Novel Text Encryption Algorithm

Abstract. The encryption/decryption processes is applied to text. Both algorithms involved the use of the associative models, in particular we propose the Alpha-Beta associative memories. The original text is divide in sets of 9 elements, and together with a secret key they build an associative memory which represents the encrypted text. The advantage of our proposal is the cyphertext does not have the same dimension that the plaintext. Additionally, the cyphertext is represented as an image, therefore, since the beginning the encrypted text has a different meaning
