France’s parliamentary intelligence delegation formally backed mandatory backdoor access to Signal, WhatsApp, and Telegram, framing the cryptographically impossible as a policy project.
Key Takeaways
The delegation recommends magistrates and intelligence agents get “targeted access” to end-to-end encrypted messages platforms cannot read themselves.
Senator Perrin’s preferred mechanism is the “ghost participant” approach: a silent state recipient added before encryption, rejected by security researchers since GCHQ floated it in 2018.
France already has extensive intercept tools: RDI device compromise authority, surveillance algorithmique, satellite interception, traditional wiretaps, and metadata access from all French telecoms.
A competing Senate amendment by Olivier Cadic would write encryption protection into French law and ban backdoor mandates; it passed the Senate in March 2025 but has stalled in the National Assembly.
The European Commission expert group is treating the backdoor technical problem as a “project management exercise,” not an unsolvable cryptographic constraint.
Hacker News Comment Review
Commenters flagged a factual error in the article: Telegram is not end-to-end encrypted by default and should not be grouped with Signal as a privacy-preserving platform.
The “targeted access” framing was treated skeptically; commenters argued bulk AI-assisted processing of collected messages is the realistic outcome, with official denial the expected cover.
No commenter disputed the core cryptographic argument: a backdoor accessible to investigators is accessible to any attacker who compromises the mechanism.
Notable Comments
@heinrich5991: Article incorrectly equates Telegram with Signal; Telegram is not E2E encrypted by default and WhatsApp is closed-source.
@pessimizer: “they definitely will slurp them all up, process them all with AI” – mass collection with AI triage, denied in public.
