This type of schemes has the following two characteristics: the commitment value of the signature is only recoverable by an intended receiver, so the value also can be used as a shared symmetric key of symmetric encryption and acts as "two birds one stone".

它有两个特点，一个是签名中的承诺值只有预定的接收者才能算出，从而又可将该承诺值用作对称加密的密钥，取得一举两得之功效；
