Abstract

Two simple redundancy schemes are shown to be inadequate in securing RSA signatures against attacks based on multiplicative properties. The schemes generalize the requirement that each valid message starts or ends with a fixed number of zero bits. Even though only messages with proper redundancy are signed, forgers are able to construct signatures on messages of their choice.

Keywords

Blind Signature False Signature Actual Message Multiplicative Property Redundancy Property 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
