Cryptic xor
WebWhile OR has a 25% chance of outputting 0 and 75% chance of outputting 1. While the XOR operation has a 50% chance of outputting 0 or 1. Let’s look at a visual example to see the different scrambling effects of AND vs. OR vs. XOR by encrypting an image . Here is a digital image of Charles Babbage: WebFeb 19, 2014 · First of all, this is XOR not subtraction. Similar bits being XOR'ed always equal 0, different bits (no matter the order) in an XOR always equal 1. 0 XOR 0 = 0, 1 …

Given that (a-b) (a-b) quite obviously computes xor for a single bit, you could construct a function with the floor or mod arithmetic operators to split the bits out, then xor them, then sum to recombine. (a-b) (a-b) = a2 -2·a·b + b2 so one bit of xor gives a polynomial with 3 terms.
WebFeb 9, 2024 · Side note however, if you're designing logical transistors (i.e. CMOS logic), then you are able to reduce the amount of transistors it will take to produce an XOR gate. The amount you have above would take 16 NMOS and PMOS transistors. However, I contend that you can reduce this down to 10. WebXOR encryption is a symmetrical encryption/decryption method based on the use of the logical/binary operator XOR (also called Exclusive Or, symbolized by ⊕ ). The XOR …
