In these schemes, the problem of 搊nce monitor, monitor for ever?is solved effectively, every escrow agency can verify correctness of the secret shadow that he escrows during secret shadow distribution and monitor agency can exactly decide which escrow agency forges or tampers secret shadow during monitor procedure.

这些方案有效地解决了&一次监听，永久监听&的问题，每个托管人能够验证他所托管的子密钥的正确性，并且在监听阶段，监听机构能够确切地知道哪些托管人伪造或篡改了子密钥。

This scheme uses random numbers to protect the secret values generated by the relative secret sharing algorithm and distributed to the participants. Therefore a group signature of an authorized subset of participants cannot be impersonated by any other set of participants, and forgers can be found. Meanwhile any participant can detect wrong secret shares.
