“Encryption Backdoors and the Fourth Amendment”

A law journal article examines the NSA’s reported efforts to induce use of vulnerable encryption (e.g., Dual_EC_PRNG) and analyzes whether the Fourth Amendment’s reasonableness requirement applies. It evaluates three theories—no search or seizure, the private-search doctrine, and the third-party doctrine—and concludes that backdoor creation can itself constitute a search or seizure, the private-search doctrine is inapplicable, and users did not waive rights, so the reasonableness requirement remains.
