In this work, a new image encryption method using a combined multilevel permutation with stream cipher is proposed. In the permutation algorithm, image is divided into blocks in each level and its blocks are rearranged by using pseudorandom permutation method. A new non linear stream cipher algorithm is also proposed that is based on combining several keys generated by Linear Feedback Shift Register (LFSR). The results shown that the proposed algorithm has a high security feature and it is efficient for image encryption. Practical tests proved that the proposed encryption algorithm is robust, provides high level of security and gives perfect reconstruction of the decrypted image.

Data encryption is the best way to provide secure communication. Even though a lot of encryption schemes are available, this paper proposes a simple, fast and secure encryption scheme. The method is suitable to encrypt smaller as well as for larger files. The approach includes two files: symmetric key file and message file, both of any format opted by the user. In this approach the hackers can't even crack which type of message file was it. So breaking cipher text becomes impossible in effect. The proposed symmetric encryption scheme has the following features over traditional schemes. First, the encryption and decryption uses the same algorithm, which is safe, simple and fast. Second, any type of file can be encrypted using this approach. Third, any type of key file can also be used according to the user's wish. In this paper, the performance is compared with the popular encryption algorithms, and the results prove that the proposed scheme is more robust and faster than traditional encryption schemes.
