Design of Digital Signature Algorithm by Fractals and Chaos Theory

Message Authentication Code is a function of the message and a secret key that produces a fixed-length value that serves as the authenticator. MAC provides authentication and confidentiality. This authentication technique does not include measures to counter repudiation by the source i.e. it does not provide digital signature. The authors propose a new Message Authentication Image (MAI) Algorithm that provides confidentiality, authentication and digital signature. It uses Cryptographic and Steganography ideas to conceal the data in the image. MAI is generated by using fractals.
