AnkeyCenter – a key generating center for the "Ancrypt"
The key generating center is a hardware/software designed for generation of
keys for the small-sized "Ancrypt" encipherer and built on the basis of "Electronika –
MK85S" micro-calculator.
A key for the "Ancrypt" encipherer consists of 110 decimal digits, of which
number 10 digits are checking digits, generated from the previous 100 digits using a
certain algorithm.
The main component of the key generating center the physical noise generating
board, which complies with the toughest requirements for such devices and their
components.
The flowchart of key generation is shown on fig. 1.
