机器人电话疫情已在美国造成数百万电话诈骗受害者，造成数十亿美元的经济损失。为了解决这个问题，联邦通信委员会(FCC)要求所有互联网电话服务提供商(ITSP)实施安全电话身份验证(STIR)，并使用令牌(Shaken)对断言信息进行基于签名的处理，以验证其网络上的互联网协议语音(VoIP)呼叫。本章分析了STIR/SHAKED在保护用户免受机器人呼叫受害者方面的有效性。机器人呼叫大多是使用虚假来电显示的诈骗电话。我们的分析显示了可能影响STIR/SHAKED有效性的三个主要问题。这些问题是(A)企业IP-PBX保护不力，(B)不良服务提供商，以及(C)缺乏对Q.1912.5的支持，Q.1912.5是IP和公共交换电话网(PSTN)之间的互通标准。
The robocall epidemic has caused millions of phone scam victims resulting in billions of financial loss in the USA. To address this issue, Federal Communication Commission (FCC) mandates all Internet Telephony Service Providers (ITSP) to implement Secure Telephony Identity Revisited (STIR) with the Signature-based Handling of Asserted information using toKENs (SHAKEN) to authenticate Voice of Internet Protocol (VoIP) calls on their networks. This chapter provides an analysis of the effectiveness of STIR/SHAKEN in protecting users from being victims of robocalls which are mostly scam calls with fake caller ID. Our analysis shows three majors issues that could have impact on the effectiveness of STIR/SHAKEN. These issues are (a) poorly protected enterprise IP-PBX, (b) unscrupulous service providers, and (c) lack of support of Q.1912.5, which is the interworking standard between IP and Public Switch Telephone Network (PSTN).
