New Attack Against RSA
By Bruce Schneier
AI Summary
Bruce Schneier clarified that a newly reported RSA attack is not novel — the underlying research dates to 2007 — and that the new implementation only enables signature forgery against unpadded, unformatted RSA signatures, not private key recovery. Practitioners should note this does not threaten properly implemented RSA with PKCS#1 or PSS padding, but it may affect legacy or non-standard deployments.
