Research on Threshold Decryption Scheme
Lin Qi-ping · Modern Computer · 2008
Uses symmetric cryptosystem and Shamir threshold scheme to construct a threshold decryption scheme. The sharing key in this threshold scheme is the symmetric key which is used in encryption, and the trusted center is the encryptor. This scheme requests that the members of the receiver have to be bigger than the threshold value, otherwise they cannot get the key. That will decrease the possibility of participant cheating.
