Authentication and digital signatures
In cryptography, the authentication problem is one of the most interesting and difficult problems to solve. Authentication is one of the most sensitive functions (as well as the most used) for the procedure of access control.
Authentication is based on three methods:
- On something that only the user knows (for example, a password)
- On something that only the user holds (a smart card, device, or a token)
- On something that characterizes the user (for example, fingerprints, an iris scan, and in general biometric characteristics of a person)
In addition to these three methods, there is one more method involving something that only the user holds, related to something that uniquely characterizes them: brain waves. For example, when you look at a picture or think about it, the brain waves activated by your brain are unique, different from any other brain waves that characterize another person.
