物联网（IoT）由智能对象和服务形成，以真实的时间进行交互，并且部署在各种应用中，例如家庭监控、医疗保健和智能城市。然而，安全问题不应被忽视，因为对手可能会利用一些安全协议设计中的漏洞。为此，在本文中，我们特别关注在资源受限的设备广播认证。当设备部署在无人值守的环境中时，此安全服务仍处于起步阶段。本文基于μTESLA协议提出了一种新的认证机制，通过有效地计算密钥泄露延迟来降低伪造数据包在接收方缓冲区中的延迟。然后，我们将此机制集成到两个协议的最先进的LEAP和LEAP++。此外，我们评估我们的解决方案的可行性进行了彻底的模拟研究，考虑到能源消耗，伪造数据包的延迟，和认证延迟。
The Internet of Things (IoT) is formed by smart objects and services to interact in real time, and that are deployed in various applications such as home monitoring, healthcare, and smart cities. However, security concerns should not be overlooked since an adversary could exploit the vulnerabilities in the design of some secure protocols. To this aim, in this paper we focus in particular on broadcast authentication in resource constrained devices. This security service is still in its infancy when devices are deployed in unattended environments. We propose a new authentication mechanism based on the state of the art protocol μTESLA, that aims to reduce the delay of forged packets in the receivers buffer, by efficiently computing the key disclosure delay. Then, we integrate this mechanism to two protocols of state of the art LEAP and LEAP++. Furthermore, we assess the feasibility of our solution with a thorough simulation study, taking into account the energy consumption, the delay of forged packets, and the authentication delay.
