In order to figure out the security problem in block cipher algorithm, the principle and the key steps of the reconstruction design are studied and analyzed, including the common models and research methods. After analysis and comparison, an S-box of the encryption algorithm based scheme is proposed and demonstrated, it combines the idea of reconstruction and the mathematical function. The simulation...
E-HATS is a symmetric key encryption algorithm which encrypts and decrypts a 128-bit data block. E-HATS inherits the simplicity, feistel nature of DES and security analogous to AES. Key Updation is addressed by 16 additional bits in the cipher key. A Dynamic Substitution Rule is used in the substitution step. At the software level, E-HATS exhibits superior avalanche characteristics, achieves a reduction...
