Abstract：The efficiency of a public-key encryption scheme proposed by P. Paillier et al. is improved. The equivalence of security of the improved encryption scheme and that of the original encryption scheme is proved. Without increasing the size of the ciphertext, the scheme is further modified into an efficient "signcryption" scheme. If necessary, the receiver can verify the integrity and source of the message at any time.
