It occured to me that the stream cipher nature of CipherClock, makes it quite easy to incorporate directly into an 18 pin integrated circuit for real time encryption/decryption of 8-bit data. The key would just have to be loaded by a serial interface or built in during fabrication (with each key getting a series of chips built for it), or loaded and then made permanent during quality testing of the completed chip before shipping to customers.
Or indeed, for hardware security within a computer system, a CipherClock module can be built into the processor and every other device on the bus (with 1 CipherClock module per 8 bits of bus.) to make all inter-device communications secure.
The main issue with these ideas is that CipherClock isn’t currently designed to operate on all 256 possible 8 bit inputs, but I could easily modify it to do so.
