VIC Cipher - A Revolutionary Leap

A Revolutionary Leap

The VIC cipher can be regarded as the evolutionary pinnacle of the Nihilist cipher family.

The VIC cipher has several important integrated components, including mod 10 chain addition, a lagged Fibonacci generator (a recursive formula used to generate a sequence of pseudorandom digits), a straddling checkerboard, and a disrupted double transposition.

Until the discovery of VIC, it was generally thought that a double transposition alone was the most complex cipher an agent, as a practical matter, could use as a field cipher.
