Point-to-point encryption (P2PE) is a standard established by the PCI Security Standards Council.The objective of P2PE is to provide a payment security solution that instantaneously converts confidential payment card (credit and debit card) data and information into indecipherable code at the time the card is swiped, in order to prevent hacking and fraud.
The KG-84C is a Dedicated Loop Encryption Device (DLED), and both devices are General-Purpose Telegraph Encryption Equipment (GPTEE). The KG-84A is primarily used for point-to-point encrypted communications via landline, microwave, and satellite systems.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [1] It can provide loop detection, authentication , transmission encryption , [ 2 ] and data compression .
The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.
The EAPOL was also modified for use with IEEE 802.1AE ("MACsec") and IEEE 802.1AR (Secure Device Identity, DevID) in 802.1X-2010 [7] [8] to support service identification and optional point to point encryption over the internal LAN segment. 802.1X is part of the logical link control (LLC) sublayer of the 802 reference model. [9]
A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
JREAP B is a synchronous or asynchronous point-to-point mode of the JREAP. This mode is similar in design to the Half-Duplex Announced Token Passing protocol used by JREAP A. This mode can be used with SHF and EHF LDR point-to-point mode synchronous connections, STU-III operations via phone lines and other point-to-point media connections.
Published in August 1999 as proposed standard RFC 2661, L2TP has its origins primarily in two older tunneling protocols for point-to-point communication: Cisco's Layer 2 Forwarding Protocol (L2F) and Microsoft's [2] Point-to-Point Tunneling Protocol (PPTP). A new version of this protocol, L2TPv3, appeared as proposed standard RFC 3931 in 2005.
