The paper presents a new ID-based directed threshold signcryption scheme derived from a bilinear pairing and a gap Diffie-Hellman groups. This scheme (called ID-DTS-DS) combines the functionalities of signature and encryption and allows a designated signcrypter to prepare an encrypted and a signed message in cooperation of an authorized subset of shareholders being in a possession of the shares related to a signcrypter’s private key. Furthermore, our scheme guarantees that an encryption and a signature process can be successfully finished only under a signcrypter’s sole control. We analyze the security of the ID-DTS-DS scheme and show its correctness, verifiable directedness, public non-repudiation verifiability, confidentiality and unforgeability.
