    en.wikipedia.org/wiki/Point-to-point_encryption

    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 party which initializes the encryption devices (typically the manufacturer of the device). The BDK is usually stored inside a tamper-resistant security module (TRSM), or hardware security module (HSM). It must remain clear that this key is not the one used to initialize the encryption device that will participate in DUKPT operations.

    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.
