Abstract: A new E-lottery scheme is proposed based on verifiable random function and multi-level hash chain.This scheme satisfies various requirements of electronic lottery and no trusted third-party is needed in the whole process.The purchaser can verify whether the winning number is forgery.This scheme has the property of anonymity,non-forgeability,non-repeatability and public verifiability.Compared with other schemes,this scheme is more efficient.

Key words: electronic lottery, verifiable random function, multi-level hash chain, interpolation polynomial
