Kerberos is a computer network authentication protocol, which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner. It is also a suite of free software published by Massachusetts Institute of Technology (MIT) that implements this protocol. Its designers aimed primarily at a client-server model, and it provides mutual authentication — both the user and the server verify each other's identity.
A signature is a handwritten (and sometimes stylized) depiction of someone's name, nickname or even a simple "X" that a person writes on documents as a proof of identity and intent. The writer of a signature is a signatory. Similar to a handwritten signature, a signature work describes the work as readily identifying its creator.
Authentication is the act of establishing or confirming something (or someone) as authentic, that is, that claims made by or about the subject are true ("authentification" is a French language variant of this word). This might involve confirming the identity of a person, tracing the origins of an artifact, ensuring that a product is what its packaging and labeling claims to be, or assuring that a computer program is a trusted one.
In computing, the Challenge-Handshake Authentication Protocol (CHAP) authenticates a user or network host to an authenticating entity. That entity may be, for example, an Internet access provider. CHAP provides protection against playback attack by the peer through the use of an incrementally changing identifier and of a variable challenge-value. CHAP requires that both the client and server know the plaintext of the secret, although it is never sent over the network.
A shibboleth is any distinguishing practice which is indicative of one's social or regional origin. It usually refers to features of language, and particularly to a word whose pronunciation identifies its speaker as being a member or not a member of a particular group.
Authorization (also spelt Authorisation) is the function of specifying access rights to resources, which is related to information security and computer security in general and to access control in particular. More formally, "to authorize" is to define access policy. For example, human resources staff are normally authorized to access employee records, and this policy is usually formalized as access control rules in a computer system.
Caller ID (caller identification, CID), also called calling line identification (CLID) or calling number identification (CNID), is a telephone service, available in analog and digital phone systems and most Voice over Internet Protocol (VoIP) applications, that transmits a caller's number to the called party's telephone equipment during the ringing signal, or when the call is being set up but before the call is answered.
Remote Authentication Dial In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting management for computers to connect and use a network service. RADIUS was developed by Livingston Enterprises, Inc. , in 1991 as an access server authentication and accounting protocol and later brought into the IETF standards.
A subscriber identity module (SIM) on a removable SIM card securely stores the service-subscriber key (IMSI) used to identify a subscriber on mobile telephony devices. The SIM card allows users to change phones by simply removing the SIM card from one mobile phone and inserting it into another mobile phone or broadband telephony device.
A remote keyless system is a system designed to remotely permit or deny access to premises or automobiles This system was invented by mechanical engineer A.B. Makkar. There are several RKE systems on the market, including but not limited to KeeLoq by Microchip, HITAG by Philips, and AVR411 by Atmel.
Evan Pugh (1859-1864)- In the Shadow of the civil war Evan Pugh became the first president of the then Farmers' High School. He was a member of the London Chemical Society and a professor at Yale University. He was burdened with meeting the objectives of the Morrill Land-Grant Act of 1862 and the necessary completion of Old Main. On May 2, 1862 Pugh had the name Farmers' High School changed to the Agricultural College of Pennsylvania.
