Some Cryptographic Aspects of Womcodes
How to prevent anyone from reusing the wom (immutable codes).
How to fix the written information in the wom after a given number of generations (locking codes).
How to encode a “credit” in a way that guarantees the user t generations or “purchases” in any possible way and makes it impossible to cheat: i.e. writing on the wom necessarily increases the spent amount of money. The coding will be called “incremental locked”.
These questions were only raised in , where the accent was put on the generation of womcodes possessing an “easy reading-reserved writing” property.
