- Jurisdiction where ciphertext is stored is irrelevant if end-to-end encryption is securely implemented.
- Jurisdiction matters for software development due to potential government backdoors like the U.S.A. P.A.T.R.I.O.T. Act and CLOUD Act.
- Open source mitigations include public software releases, reproducible builds, and digital signatures for supply-chain security.
- Key transparency is crucial for end-to-end encrypted messaging apps to prevent key substitution attacks.
- Threshold signatures, like FROST, can remove single points of failure in software signing by distributing the signing key.
- FREON is a new tool implementing FROST for Ed25519 signatures, aimed at securing Git releases and other protocols.
- Freon includes client and coordinator software for decentralized, secure signing ceremonies, with future enhancements planned.
