Rubber hose cryptanalysis
Rubber-hose cryptanalysis (translated rubber hose cryptanalysis ) is a euphemism that allows the use of torture with the intention of a person to surrender a password or decryption key will bring, called. Although the term itself is originally derived from a method of torture in which someone is repeatedly hit on the soles of the feet with a rubber hose, it is representative of all kinds of possible torture methods.
The origin of this expression can be found in Usenet . The original English definition is:
“In which [meant: in rubber-hose cryptanalysis] a rubber hose is applied forcefully and frequently to the soles of the feet until the key to the cryptosystem is discovered, a process that can take a surprisingly short time and is quite computationally inexpensive. ”
"During [meaning: rubber tube cryptanalysis] a rubber tube is applied forcefully and frequently to the soles of the feet until the key to the cryptosystem is discovered, a process that can take surprisingly little time and requires very little computational effort."
This term is often used to show that in addition to cracking the encryption code, which is usually extremely time-consuming, methods such as torture, extortion , bribery, social engineering and the like are available to get encrypted secrets. He gave his name to the Rubberhose encryption software developed in 1997 , with which the concept of credible deniability was to be implemented.
