A Novel Security Scheme based on Twofish and Discrete Wavelet Transform
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2017, Vol 8, Issue 5
Abstract
Nowadays, there is a huge amount of data exchanged between different users; the security of the exchanged data has become a significant problem due to the existing of several security attacks. So, to increase the confidence of users several security techniques can be used together to enhance the level of security. In this research paper a new secure system is proposed. The proposed system employs cryptography and steganography together. The combination between cryptography and steganography contributes in increasing the security level to provide a robust system that can resist the security attacks. In this paper, the Twofish block cipher based cryptography is employed to encrypt the data. The Twofish permits trade-offs between speed, key setup time, software size, memory, and security level. The steganographic algorithm employed to hide the encrypted data into an image is the discrete wavelet transforms (DWT) algorithm. Different security tests are used to evaluate the security and functionality of the suggested algorithm, such as, the peak signal to noise ratio (PSNR) analysis and histogram analysis. The results reveal that, the algorithm proposed in this paper is secure.
