Design and Implementation of Android Based Text Encryption and Decryption Technique

The rise of internet has created a major challenge for securing sensitive information sent over the network. Several solutions have been proposed in the past to protect user data. Encryption algorithm is one of them. At present, various types of encryption algorithms like AES, DES, RSA and others are available. In this report, we have proposed an algorithm for ourselves which is 128-bit text size and 128-bit key size. We have compared the proposed algorithm with different algorithm comparisons. The result is showing our proposed algorithm gives better performance. By the difference we see that our recommended encryption process's average runtime is 0.006 sec which is less than other algorithms (AES, DES). It also protects various cryptanalytic attacks - key attack, brute force attack, man in the middle attack and it is also suitable for the implementation of software and hardware
