Abstract: Information security becomes very significant in data storage. However, widespread popularity of wireless data communication gadgets, integrated with the availability of higher bandwidths, has led to an increased user demand for multi media content rich information and images. To make the cipher more robust against any attack, the confidential key created must have high randomness. It is very significant in constructing cryptographic keys and its algorithm. The Chaotic - maps are the best alternatives for generation of random secret keys, since they have desirable properties of ergodicity and high sensitivity to initial conditions and other control parameters. Most chaotic- maps are as equivalent as traditional pseudo - random secret keys for multimedia content rich data encryption. In this paper, we have presented two different approaches, new permutation-substitution based random sequence generation from an image pixel and blended chaotic Blum Blum Shub shub.A ne!
w approach is proposed to generate a random-bit sequence with a high degree of randomness. The proposed algorithm is a better alternative to satisfy the need for information security services. In this regard, we have developed an algorithm for the generation of random sequence of length 256 by shuffling and blending of image pixel based on Base 64 encoding and integrated chaotic Blum Blum Shub. The performance analysis of the proposed new approach is tested for randomness by carrying out various testing rules and statistical test. Results of the various types of analysis are encouraging and imply that the proposed approaches are very successfully able to adeptly the trade offs between the speed and protection. Hence it is suitable for the real-time transmission of image and video communication applications.
