Generating a suitable secret key with faciliting its saving and remembering

Abstract

Nowadays, most people use cryptography to deal with sensitive information either during storing or during communication. Dealing with cryptography requires secret or privet keys. But some of users use unsuitable secret keys. They use either short, or weak keys. The short and weak keys are easy to be remembered. The risk of using weak or short keys is that the weak key can be guessed and the short key can be broken easily. In cryptography, it is known that the security produced are directly proportional to the quality and the length of the used secret keys. On security rules, secret key should not be saved or written in any file or written, because it weakens the associated security. This paper suggests a method to remember a long secret key easily by assigning a suitable name to each finger of the two hands, selecting start and end points, selecting predefined path, and finger sequence. The collection of symbols to the finger-names between the start and end points at the predefined path is the secret key.
