RSA Encryption
Definition
RSA is a public-key cryptosystem invented in 1977, widely used for secure communications and digital signatures. Its security relies on the difficulty of factoring large prime products. Shor's algorithm factors integers efficiently, making RSA completely vulnerable to quantum computers.
Technical Explanation
RSA key generation multiplies two large primes (p×q=n). The public key includes n and an exponent e; the private key contains the factorization. Encryption raises messages to power e mod n; decryption uses the private exponent d. Factoring n reveals d, breaking security.
Classical factoring algorithms require exponential time; the current RSA record is 829 bits. Shor's algorithm factors in polynomial time, and the estimated cost keeps collapsing: Craig Gidney's May 2025 analysis puts RSA-2048 within reach of under 1 million noisy qubits in under one week, down from 20 million qubits and 8 hours in the 2019 estimate. RSA-2048, once considered safe for decades, has a limited quantum-era lifespan — and it is not even the nearest target. ECDSA-256, the signature scheme guarding cryptocurrency, is cheaper still.
SynX Relevance
SynX avoids RSA entirely, implementing only quantum-resistant algorithms. Kyber-768 replaces RSA for key encapsulation; SPHINCS+ replaces RSA for signatures. No RSA dependency means no RSA vulnerability—SynX is quantum-resistant by design, not by upgrade.
Frequently Asked Questions
- Is longer RSA key length a solution?
- No—Shor's algorithm breaks RSA regardless of key size; larger keys only slightly delay attacks.
- Is RSA used in cryptocurrency?
- Rarely directly; ECDSA is more common. But RSA appears in TLS, wallet infrastructure, and exchanges.
- When will RSA be broken?
- When cryptographically relevant quantum computers exist—the roadmap puts that window at 2029–2033, from IBM Starling (2029) to Blue Jay (2033).
