SGS (formerly Société Générale de Surveillance (French for General Society of Surveillance )) is a Swiss multinational company headquartered in Geneva, which provides inspection, verification, testing and certification services. Its 99,600 employees operate a network of 2,600 offices and laboratories worldwide. [2] It ranked on Forbes Global 2000 in 2015, [3] 2016, [4] 2017, [5] 2020 [6 ...
Serge Massar was born in Zambia in 1970. [2] He obtained a degree in physics, then a PhD from the Université libre de Bruxelles (ULB) in 1991 and 1995, respectively. [2] He completed his post-doctoral research at Tel Aviv University from 1995 to 1997, and subsequently at Utrecht University from 1997 to 1998. [2] [3]
Other shared authentication schemes, such as OpenID and OpenID Connect, offer other services that may require users to make choices during a sign-on to a resource, but can be configured for single sign-on if those other services (such as user consent) are disabled. [4] An increasing number of federated social logons, like Facebook Connect, do require the user to enter consent choices upon ...
In cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity -checking a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity). The MAC value allows verifiers (who also possess a secret key) to detect ...
Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works. When used in conjunction with an electronic signature, it can provide evidence of ...
Add an extra security step to sign into your account with 2-step verification. Find out how to turn on 2-step verification and receive a verification code, and how to turn off 2-step verification if you need to.
In cryptography, the Salted Challenge Response Authentication Mechanism ( SCRAM) is a family of modern, password-based challenge–response authentication mechanisms providing authentication of a user to a server. As it is specified for Simple Authentication and Security Layer (SASL), it can be used for password-based logins to services like LDAP, HTTP, SMTP, POP3, IMAP and JMAP ( e-mail ...
Mutual authentication is often employed in the Internet of Things (IoT). Writing effective security schemes in IoT systems is challenging, especially when schemes are desired to be lightweight and have low computational costs. Mutual authentication is a crucial security step that can defend against many adversarial attacks, [3] which otherwise can have large consequences if IoT systems (such ...
