由于数字签名方案无法保证谁是经签名的消息的目标接收方，那么也就没有人能确定恶意方声明的真实性。

Because the digital signature scheme guarantees nothing about who is the intended recipient of the signed message, nobody can determine whether the malicious party's claim is true or not.

不幸的是，泛型的复杂性(包括可能出现的各种上下界变化等)意味着签名无法像描述符那样简单地说明。

Unfortunately, the complexity of generic types (including all the possible variations of bounds and such) means that signatures cannot be described as simply as the descriptors.
