Bitwise substitution
WebMar 6, 2011 · This isn't a bitwise XOR - it's effectively a bitwise substitution cypher. You realise it's only "encryption" in the loosest sense of the word, right? Basically you'll need two steps: Write methods to transpose bits for encryption/decryption, each one taking a 32-bit integer and returning a 32-bit integer; WebJan 6, 2024 · Abstract: In a tracking device system, a networked smart device is enabled to cause execution of an executable function if a trigger condition of a conditional rule is satisfied. The conditional rules are customizable on a user interface of the smart device. The trigger condition may be any information received in a signal from a tracking device, for …
