RSA SecurID

摘要

Passwords are something which normal users don't really care about. Some write them on their desk, while others put passwords which are nothing but their name or surname. Moreover, they reveal their passwords to all and sundry, maybe even a a social engineer whom they met last night. Additionally, there are threats like sniffers and Trojans, phishing attacks etc. To overcome these problems RSA SecurlD uses a two-factor authentication which is based on something you know—a password or PIN (personal identification number) and something you can keep—a hardware token. Just like ATMs where a PIN and an ATM card together provide you with two-factor authentication. RSA replicates a similar kind of authentication through a PASSCODE. It is created with a PIN combined with the number displayed on the RSA SecurlD token.
