	Abstract:	A (t, n) threshold proxy signcryption scheme allows t or more proxy signcrypters from a designated group of n proxy signcrypters to signcrypt messages on behalf of an original signcrypter. In this paper, a new identity-based threshold proxy signcryption scheme from bilinear pairings is proposed. Our construction is based on Baek and Zheng's pairing-based verifiable secret sharing scheme and Libert and Quisquater's identity-based signcryption scheme. As compared to Wang and Liu's identity-based threshold proxy signcryption scheme, our scheme is more secure and efficient.
