Security Assertion Markup Language (SAML) is a set of specifications that encompasses the XML-format for security tokens containing assertions to pass information about a user and protocols and profiles to implement authentication and authorization scenarios.
Keycloak is an open-source software product to allow single sign-on with identity and access management aimed at modern applications and services. Until April 2023, this WildFly community project was under the stewardship of Red Hat , who use it as the upstream project for their Red Hat build of Keycloak .
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
A user wielding a user agent (usually a web browser) is called the subject in SAML-based single sign-on. The user requests a web resource protected by a SAML service provider. The service provider, wishing to know the identity of the user, issues an authentication request to a SAML identity provider through the user agent.
User-made passwords and the ability to change one's password are important for making an application user-friendly, [15] so many schemes work to accommodate the characteristic. Researchers note that a password based protocol with mutual authentication is important because user identities and passwords are still protected, as the messages are ...
Identity-based systems have a characteristic problem in operation. Suppose Alice and Bob are users of such a system. Since the information needed to find Alice's public key is completely determined by Alice's ID and the master public key, it is not possible to revoke Alice's credentials and issue new credentials without either (a) changing Alice's ID (usually a phone number or an email address ...
The Subject Information Access extension can carry a URI to point to certificate repositories and timestamping services. Hence this extension allows to access services by several different protocols (e.g. HTTP, FTP, LDAP or SMTP). Although encouraged, usage of the AIA and SIA extension is still not widely deployed. There are two main reasons ...
Once a user has accepted another user's fingerprint, that fingerprint (or the key it refers to) will be stored locally along with a record of the other user's name or address, so that future communications with that user can be automatically authenticated. In systems such as X.509-based PKI, fingerprints are primarily used to authenticate root ...
