Better than BiBa: Short One-time Signatures with Fast Signing and Verifying

Leonid Reyzin and Natan Reyzin

Abstract: One-time signature schemes have found numerous applications: in ordinary, on-line/off-line, and forward-secure signatures. More recently, they have been used in multicast and broadcast authentication. We propose a one-time signature scheme with very efficient signing and verifying, and short signatures. Our scheme is well-suited for broadcast authentication, and, in fact, can be viewed as an improvement of the BiBa one-time signature (proposed by Perrig in CCS 2001 for broadcast authentication).
