Exam 312-50v11 topic 1 question 78 discussion

In cryptography, rubber-hose cryptanalysis is a euphemism for the extraction of cryptographic secrets (e.g. the password to an encrypted file) from a person by coercion or torture—such as beating that person with a rubber hose, hence the name—in contrast to a mathematical or technical cryptanalytic attack.

Cryptographic systems depend on the concealment of secret keys shared by the participants. However, in general, systems are not able to resist coercion attacks. In these attacks, the participant is forced by the adversary to surrender the key. This type of attacks, known as a rubber hose attack, is in many instances the least costly method, in time and effort, that are utilized to defeat cryptography.
