Mutual authentication is a desired characteristic in verification schemes that transmit sensitive data, in order to ensure data security. [1] [2] Mutual authentication can be accomplished with two types of credentials: usernames and passwords, and public key certificates. Mutual authentication is often employed in the Internet of Things (IoT ...
National Identity Management Commission 08125575121 (NIMC) is a statutory Nigerian organization that operates the country's national identity management systems. It was established by the NIMC Act No. 23 of 2007 to create, operate and manage Nigeria's national identity card database, integrate the existing identity database in government institutions, register individuals and legal residents ...
IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using DNS (preferably with DNSSEC) ‒ and a Diffie–Hellman key exchange to set up a shared session secret from which cryptographic keys are derived. [2] [3] In addition, a security policy for every peer which will connect must be manually maintained. [2]
An alternative approach to the problem of public authentication of public key information is the web-of-trust scheme, which uses self-signed certificates and third-party attestations of those certificates. The singular term "web of trust" does not imply the existence of a single web of trust, or common point of trust, but rather one of any ...
The ISRG provides free and open-source reference implementations for ACME: certbot is a Python-based implementation of server certificate management software using the ACME protocol, [6] [7] [8] and boulder is a certificate authority implementation, written in Go. [9] Since 2015 a large variety of client options have appeared for all operating ...
The protocol enables users to securely exchange secret keys even if an opponent is monitoring that communication channel. The D–H key exchange protocol, however, does not by itself address authentication (i.e. the problem of being sure of the actual identity of the person or 'entity' at the other end of the communication channel).
Certificate-based encryption is a system in which a certificate authority uses ID-based cryptography to produce a certificate. This system gives the users both implicit and explicit certification, the certificate can be used as a conventional certificate (for signatures, etc.), but also implicitly for the purpose of encryption.
Anonymous key exchange, like Diffie–Hellman, does not provide authentication of the parties, and is thus vulnerable to man-in-the-middle attacks. A wide variety of cryptographic authentication schemes and protocols have been developed to provide authenticated key agreement to prevent man-in-the-middle and related attacks.
