Token Binding is a proposed standard for a Transport Layer Security (TLS) extension that aims to increase TLS security by using cryptographic certificates on both ends of the TLS connection. Current practice often depends on bearer tokens, [ 1 ] which may be lost or stolen.
Tokens can contain chips with functions varying from very simple to very complex, including multiple authentication methods. The simplest security tokens do not need any connection to a computer. The tokens have a physical display; the authenticating user simply enters the displayed number to log in.
Security token service (STS) is a cross-platform open standard core component of the OASIS group's WS-Trust web services single sign-on infrastructure framework specification. cf. [1] [2] Within that claims-based identity framework, a secure token service is responsible for issuing, validating, renewing and cancelling security tokens. The ...
While RSA SecurID tokens offer a level of protection against password replay attacks, they are not designed to offer protection against man in the middle type attacks when used alone. If the attacker manages to block the authorized user from authenticating to the server until the next token code will be valid, he will be able to log into the ...
In computer systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it therefore should ...
A security token is an example of a possession factor. Disconnected tokens have no connections to the client computer. They typically use a built-in screen to display the generated authentication data, which is manually typed in by the user. This type of token mostly uses a OTP that can only be used for that specific session. [6] A USB security ...
The most popular type of security token (RSA SecurID) displays a number which changes every minute. Users are authenticated by entering a personal identification number and the number on the token. The token contains a time of day clock and a unique seed value, and the number displayed is a cryptographic hash of the seed value and the time of day.
Tokenization, when applied to data security, is the process of substituting a sensitive data element with a non-sensitive equivalent, referred to as a token, that has no intrinsic or exploitable meaning or value. The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system.
