对时间段身份验证的改进
Improvements to time bracketed authentication
摘要：
我们描述了一系列技术，通过这些技术，重要事件的视听或其他记录可以以某种方式进行，从而阻止相关方，甚至是记录设备的制造商和操作者进行伪造，提前或推迟。这些技术的一个核心特征是私人信息与公共信息之间的相互作用，私人信息本质上是不可信的，容易受到利益相关者的压制或操纵，而公共信息则广为人知，不会被任何人操纵。虽然经过认证的录音可能无法伪造，但它们可以以其他方式被滥用，例如用于勒索或骚扰;但加密和秘密共享可以减少这些滥用的可能性。
英文摘要：
We describe a collection of techniques whereby audiovisual or other recordings of significant events can be made in a way that hinders falsification, pre-dating, or post-dating by interested parties, even by the makers and operators of the recording equipment. A central feature of these techniques is the interplay between private information, which by its nature is untrustworthy and susceptible to suppression or manipulation by interested parties, and public information, which is too widely known to be manipulated by anyone. While authenticated recordings may be infeasible to falsify, they can be abused in other ways, such as being used for blackmail or harassment; but susceptibility to these abuses can be reduced by encryption and secret sharing.
