In this paper, we analyse Ma signcryption scheme proposed in Inscrypt'2006. Although Ma signcryption scheme is probably secure against adaptive chosen ciphertext attacks and forgery, we show that Ma signcryption scheme is easily forgeable by the receiver and the receiver can impersonate the sender to forge any valid signcryption to any receiver.
