end-to-end - 2024 ARCADIA - Buzzpoints App

Question

A Saltzer, Reed, and Clark network design paper argues for a principle of this name, stating that network functions like reliability can only be implemented at the application level. For 10 points each:

[10e] What phrase describes a scheme in which only the sender and recipient can encrypt and decrypt data? This three-word phrase is the default encryption scheme for platforms like Facebook Messenger and Zoom.

ANSWER: end-to-end [or E2E; accept end-to-end encryption or end-to-end principle; accept “End-to-End Arguments in System Design”]

[10m] The paper illustrates the end-to-end principle using the example of “carefully” performing this task with a checksum. SSH is often used to secure a namesake protocol for this task that is abbreviated FTP.

ANSWER: file transfer [accept File Transfer Protocol; reject “for 10 points”]

[10h] The end-to-end principle is violated in an issue with this anatomy-influenced name, where existing middleboxes prevent new protocols from being deployed. This issue occurs when old low-level protocols prevent deployment of newer standards.

ANSWER: ossification [accept protocol ossification]
