RSA SecurID (new style, SID800 model with smartcard functionality) The RSA SecurID authentication mechanism consists of a ' — either hardware (e.g. A ) or software (a ) — which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random (known as the 'seed').

The seed is different for each token, and is loaded into the corresponding RSA SecurID server (RSA Authentication Manager, formerly ACE/Server ) as the tokens are purchased. On-demand tokens are also available, which provide a tokencode via email or SMS delivery, eliminating the need to provision a token to the user. The token hardware is designed to be to deter.

When software implementations of the same algorithm ('software tokens') appeared on the market, public code had been developed by the security community allowing a user to emulate RSA SecurID in software, but only if they have access to a current RSA SecurID code, and the original 64-bit RSA SecurID seed file introduced to the server. Later, the 128-bit RSA SecurID algorithm was published as part of an open source library. In the RSA SecurID authentication scheme, the seed record is the secret key used to generate. Newer versions also feature a USB connector, which allows the token to be used as a -like device for securely storing. A user authenticating to a network resource—say, a dial-in server or a firewall—needs to enter both a and the number being displayed at that moment on their RSA SecurID token. Though increasingly rare, some systems using RSA SecurID disregard PIN implementation altogether, and rely on password/RSA SecurID code combinations. The server, which also has a real-time clock and a database of valid cards with the associated seed records, authenticates a user by computing what number the token is supposed to be showing at that moment in time and checking this against what the user entered.
