Xin Lv, Congming Wang · 2010
The paper proposes a publicly verifiable threshold decryption scheme with no center based on the situation that a trust center does not exist in many special occasions. The scheme asks decryption member for submitting commitment in the decryption process in order to make sure the identity is publicly verifiable. Moreover, the scheme has several advantages such as protecting the shadow without revealing and the members can be deleted dynamically.
