Adapted Encryption Algorithm with Multiple Skew Tent Map

In recent years, the chaos based cryptographic algorithms have some optional and efficient waysto develop secure encryption techniques. In this paper, we proposed a modified approach for encryptionbased on chaotic skew tent maps in order to meet the requirements of the secure transfer. In the projectedencryption scheme, an external secret key of 128-bit and two chaotic skew tent maps are employed. Theinitial conditions for the both skew tent maps are derived using the external secret key. The results of severalexperimental, statistical analysis and key sensitivity tests show that the proposed encryption scheme providesan efficient and secure way for encryption and transmission.
