An Encryption Algorithm Based on Recurrent Appell's Hypergeometric Functions of Two Variables

This paper introduces a novel method based on symmetric cryptography relying on Appell's recurrent hypergeometric functions of two variables. The implementation was done in C# and our method compared to standard methods when it comes to encryption and decryption processing time: DES, 3DES, Caesar cipher and RSA. The achieved results seem promising as it outperforms DES algorithm which represented de facto standard in cryptography for long period.
