Shamir Secret Sharing
Definition
Shamir Secret Sharing splits a secret into multiple shares, requiring a threshold number to reconstruct. Any fewer shares reveal nothing about the secret. Used for key backup, inheritance planning, and distributed custody. The scheme is information-theoretically secure.
Technical Explanation
Algorithm: secret is the constant term of a random polynomial; shares are points on the polynomial. t+1 points reconstruct degree-t polynomial via Lagrange interpolation. Fewer points give no information about the constant (secret).
Quantum resistance: Shamir's scheme uses finite field arithmetic—not public-key cryptography. No quantum algorithm breaks information-theoretic security. The scheme remains perfectly secure against quantum computers.
SynX Relevance
Split your SynX seed phrase or master key using Shamir sharing for backup redundancy. 3-of-5 shares mean any 3 trustees can recover your wallet; fewer cannot. Perfect for inheritance and distributed backup—quantum-proof by design.
Frequently Asked Questions
- Is Shamir sharing quantum-resistant?
- Yes—it's information-theoretically secure. No algorithm (classical or quantum) can break it.
- What threshold should I use?
- 2-of-3 for simple backup; 3-of-5 for more redundancy. Balance recovery ease with security.
- Can I use Shamir for my SynX seed?
- Yes—split your 24-word phrase or master entropy. Tools like SLIP-39 standardize this.
