Abstract :
A new method of secure multi-party multiplication using bilinear pairing is constructed. First of all, a protocol of signcryption based on bilinear pairing is proposed, which satisfy the secure requirements of forward security, publicly verifiability and so on. Secondly, a protocol of secure two-party multiplication using the signcryption and oblivious transfer is constructed and a protocol of secure multi-party multiplication is deduced. In the protocol, malicious participants can´t temper the message and it can prevent the k-1 numbers participants from cheating the other together.
