Caesar Cipher Function in Python - Stack Overflow

WebSep 9, 2024 · I am trying to figure out the process behind the Speck block cipher. I understand how XOR works (Exclusive-or) when you take 2 strings of bits and you want to XOR them together. However, in the key schedule of the cipher, there is a point where XOR takes place but I don t understand what is being XORed. WebAs a result, ciphers employing the modular addition as their only source of nonlinearity are a promising target for research in white-box cryptography based on self-equivalence encodings. ... We also created a Python implementation of our white-box speck method, capable of generating correct white-box speck code. This allows us to compare protein queen official
