WebThere are many other types of attacks, including side-channel attacks, which attack the weaker links in cryptography like the implementation of the cipher or the people who use it. One particularly disturbing side-channel attack is rubber-hose cryptanalysis, in which a person is compelled to reveal secret data by force (typically physical, but could also be … Web"staff cipher"). Messages were written down the length of the staff, and the papyrus was unwrapped. In order to read the message, the papyrus had to be wrapped around a staff of equal diameter. Called the 'skytale' cipher, this was used in the 5th century B.C. to send secret messages between greek warriors.
