With the fast progression of digital data communication in an electronic way, information security is becoming an issue in the modern advancing technology. Cryptography is one of the techniques of modern electronic security that serves the purpose of maintaining information security. There are numerous ways to encrypt and decrypt information for maintaining security. In this paper, a bit-shuffled improved tent map based image encryption technique is proposed. The implementation is based on the improved tent map combined with bit-shuffling operation using random sequence. The simulation results and security analysis shows that the proposed algorithm is resistive to brute-force attacks, statistical attacks, differential attacks, sensitive to secret keys and have more randomness. The proposed scheme is efficient and reliable and this technique can be applied in various fields where confidentiality of image is needed during communication and transmission such as in Governments, military, financial institutions, hospitals, etc.
