RSA SecurID®
The RSA SecurID® authentication is the Strongest and Easiest to Use One Time Password Security Solution, there have been no reported security breaches of RSA SecurID® authentication in over 15 years. The token hardware is designed to be tamper-resistant to deter reverse engineering of the token. RSA SecurID® currently commands over 70% of the two-factor authentication market (source: IDC) and 25 million devices have been produced to date.
To protect your organization's most critical information assets, you need a security system that is second to none. RSA SecurID® authentication offers a unique, time-synchronous solution** that automatically changes the user's authentication code every 60 seconds using a built-in clock and the card's factory-encoded random key. This makes RSA SecurID® solution more secure than event-synchronous systems with passwords that can be valid for an indefinite period of time and easier to use than challenge-response systems that require multiple steps to generate a valid code.
What's more, RSA SecurID® authentication is built upon the Advanced Encryption Standard (AES**) algorithm, a recognized standard that is continuously scrutinized and challenged by cryptologists around the World to ensure its strength and dependability.
Remark
• Time synchronous authentication is an authentication method that relies on a timing value to authenticate the token bearer. All token authentication applications work with an input value from some source. The input value is encrypted according to some algorithm, using a key. The encrypted value is displayed as a one-time password that the token bearer types into a computer or other device to gain access. In time synchronous authentication, both the token, often called a hardware authenticator, and the server keep track of clock time. The clock time is the input value for the encryption process and it's encrypted with the seed record. The resulting value is entered as a one-time password at the login prompt. The server does the same computation in order to authenticate the token bearer.
• The Advanced Encryption Standard (AES) was introduced in 2000 after a long search by NIST for an encryption standard that would be hard to break, inexpensive to use, easy to implement and would work on both hardware and software. One of the two important factors that make an encryption standard hard to break is the encryption process (encryption algorithm). Theories can't accurately predict how easy it will be to break a particular algorithm, so NIST published a few contenders and experts all over the world tried to break them. The second factor in making an encryption standard hard to break, especially a standard based on symmetric key cryptography, or a shared secret, is the key length. In general, the longer the key, the harder it is to figure it out by just trying random strings of characters. The AES can use a key length of 128, 192 or 256 bits. The algorithm to be chosen also had to be made available to the public without royalty fees. After years of testing and multiple ems cycles, the Rijndael algorithm, written by two Belgium cryptographers, was adopted as the AES and was published as FIPS 192. There is an inherent weakness in a symmetric key process because the key has to be transferred from the sender to the receiver as well as the encrypted text. Frequently, AES is used as part of a set of encryption tools where an asymmetric encryption method is used to transfer the key.
