OCSP suffers from scalability issues. It relies on the client having network access at the time of checking the certificate's revocation status; further, the OCSP responder must be accessible and produce usable responses, or else the check will fail and the client must choose between failing-soft and failing-hard.
TSIG uses shared secret keys and one-way hashing to provide a cryptographically secure means of authenticating each endpoint of a connection as being allowed to make or respond to a DNS update. Although queries to DNS may usually be made without authentication, updates to DNS must be authenticated, since they make lasting changes to the ...
Token-based authentication mechanisms, such as Azure AD authentication, may affect connection pooling due to token expiration. Expired tokens can invalidate connections within the pool, interrupting reuse. This behavior is observed in both cloud-based and on-premises database systems that implement modern authentication protocols.
The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [2] It is described in RFC 6960 and is on the Internet standards track.
Data is encrypted to make it secret, such that even if it was read, it appears as gibberish. Perhaps the most common use of PKI for confidentiality purposes is in the context of Transport Layer Security . TLS is a capability underpinning the security of data in transit, i.e. during transmission.
The client and server then use the random numbers and PreMasterSecret to compute a common secret, called the "master secret". All other key data ("session keys") for this connection is derived from this master secret (and the client- and server-generated random values), which is passed through a carefully designed pseudorandom function.
Security Assertion Markup Language (SAML, pronounced SAM-el, / ˈ s æ m əl /) [1] is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider.
The bank or credit network embeds their secret key into the card's secure key storage during card production at a secured production facility. Then at the point of sale the card and card reader are both able to derive a common set of session keys based on the shared secret key and card-specific data (such as the card serial number). This method ...
