Abstract:
Blind signature schemes are the essential element of many e-cash and e-voting systems. Anonymity in such systems is ensured through the blindness property of the signature schemes. We discuss the blindness property and analyze several ElGamal-type blind signature schemes regarding this property. We present effective attacks violating blindness on three schemes.
Keywords:
blind signature scheme, blindness, ElGamal-type blind signature.
