For example, the MixColumns matrix step in AES cipher is matrix multiplication. The function g in Twofish is a combination of non-linear algebra S-boxes i.e substitution boxes with a carefully chosen matrix multiplication (MDS) is used this....
Now,'NA'will be replaced with'UE'. Similarly,"MY NA ME IS PO GO"will become"KZ UE FA LO DS BS". For the decryptionprocess, we will just follow the exact opposite steps. 3) Hill Cipher The Hill cipher is based on polygraphic substitution that is it works on multiple letter...

This paper devotes to construct Hill cipher by using partial differential equations (PDEs).Encryption and decryption models based on the first-order hyperbolic equation with mixed boundary conditions are proposed.Matrix functions according to the difference schemes are Designed.The improved Hill cipher ...
SM3 is password hash algorithm, SM4 is a block cipher used to replace DES / AES and other international algorithms. SM9 is an identity-based cryptographic algorithm that can replace PKI / CA based on digital certificate. By deploying the secret algorithm, you can reduce the security risks ...
