Abstract
A transaction discovery protocol determines when a value r is less than a value a without learning the value of r or a. The protocol (1) receives, at a first computer via a secure communication channel, value a, where x is a secret key unknown to the first computer; (2) generates vector B where a first entry is the value r, and subsequent entries are equal to the previous entry plus a predefined resolution; (3) generates vector Bfrom the vector B using secret key y, unknown to a second computer, and sends vector Bto the second computer; (4) receives vector Bfrom the second computer and generates value a; and (5) completes an agreement between the first computer and the second computer when the value ais equal to one of the entries in the vector B, indicating that the value r is less than the value a.
