OSS signature scheme

OSS signature scheme

A method for digitally signing a message is described. The method includes providing a message digest (Mx, Mz), providing a modulus N, providing a number V in a ring ZN, wherein for another number S in the ring ZN, V.S2=1 in ZN, solving the equation (Mx+X)2-V.y2=4.(Mz+z) in ZN to produce x, y, and z...

Zusammenfassung:A method for digitally signing a message is described. The method includes providing a message digest (Mx, Mz), providing a modulus N, providing a number V in a ring ZN, wherein for another number S in the ring ZN, V.S2=1 in ZN, solving the equation (Mx+X)2-V.y2=4.(Mz+z) in ZN to produce x, y, and z, and assigning SIG as the signature of MX, MZ), wherein SIG includes (x,y). Related methods and apparatus are also described.
