This document presents a novel encryption and decryption process using permutation choice. It proposes a method with single round encryption and decryption, key generation, and a round function. The round function selection inputs determine which of 16 possible round functions to use. The proposed method aims to provide more secure encryption by making cryptanalysis more difficult through changing the round function from round to round and altering plaintext values. It concludes by thanking the audience.

- 18. The goal of the encryption algorithm designing is to frustrate the hackers and makes the cryptanalysis difficult. The key value play more important role in encryption process. Altering each value of the plain text to get the final cipher text make the cryptanalysis still more complex. The goal of the present paper is to increase the security which makes complex to break. The round function and permutation choices are not fixed, it is changed according to the user. Conclusion:
