This increases security since Henry can’t intercept and reuse an authenticator transmitted by Cathy’s device. However, it may also inconvenience Cathy if she is able to access her mail only from access points that have the particular device. The appropriate verification procedures usually fall into two categories: those using secret-key cryptography and those using public-key cryptography. The first password tokens were implemented using secret-key cryptography. To log in with one of the earliest tokens, Cathy needed to follow this procedure: 1.

All authentication factors suffer from fundamental weaknesses. Practical systems incorporate at least two factors to neutralize individual weaknesses. Plastic cards for ATMs provide a classic example: Cathy must possess the correct card and she must know the appropriate PIN; otherwise she can’t use the teller machine. Most password tokens incorporate PINs in some fashion, and most biometric systems rely on token-like devices to collect readings and to protect them cryptographically. We use authentication systems because people occasionally try to misrepresent their identities.
