Rohrbach's maxim
In cryptology , Rohrbach's maxim describes a motto that the German mathematician and cryptologist Hans Rohrbach (1903-1993) formulated. He advises that when assessing the security of a cryptological method , the possibility of encryption errors should also be taken into account, and points out that it cannot be expected that a key machine or cryptosystem will ever be used error-free at all times.
Rohrbach's maxim is:
"When assessing the cryptanalytic security of a procedure, encryption errors and other violations of the encryption discipline must be included."
