As an example of domain of use, connection-oriented protocols and connectionless protocols are used on connection-oriented networks and connectionless networks respectively. An example of function is a tunneling protocol , which is used to encapsulate packets in a high-level protocol so that the packets can be passed across a transport system ...
An eschatocol, or closing protocol, is the final section of a legal or public document, which may include a formulaic sentence of appreciation; the attestation of those responsible for the document, which may be the author, writer, countersigner, principal parties involved, and witnesses to the enactment or the subscription; or both.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Protocol (object-oriented programming), a common means for unrelated objects to communicate with each other (sometimes also called interfaces) Communication protocol, a defined set of rules and regulations that determine how data is transmitted in telecommunications and computer networking Cryptographic protocol, a protocol for encrypting messages
The use of SACK has become widespread—all popular TCP stacks support it. Selective acknowledgment is also used in Stream Control Transmission Protocol (SCTP). Selective acknowledgements can be 'reneged', where the receiver unilaterally discards the selectively acknowledged data.
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It uses encryption for secure communication over a computer network, and is widely used on the Internet. [1] [2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL).
Protocols are used mainly by Point-to-Point Protocol (PPP) servers to validate the identity of remote clients before granting them access to server data. Most of them use a password as the cornerstone of the authentication. In most cases, the password has to be shared between the communicating entities in advance. [5] PAP 2-way handshake scheme
More generally, when evaluating protocols, it is important to state security goals and the security model. [4] For example, it may be required for the session key to be authenticated. A protocol can be evaluated for success only in the context of its goals and attack model. [5] An example of an adversarial model is the Dolev–Yao model.
