The concept of Smart Home drives the upgrade of home devices from traditional mode to an Internet-connected version. Instead of developing the smart devices from scratch, manufacturers often utilize existing smart home solutions released by large IT companies (e.g., Amazon, Google) to help build the smart home network. A smart home solution provides components such as software development kit (SDK) and relevant management system to boost the development and deployment of smart home devices. Nonetheless, the participating of third-party SDKs and management systems complicates the workflow of such devices. If not meticulously assessed, the complex workflow often leads to the violation of privacy and security to both the consumer and the manufacturer. In this paper, we illustrate how the security and privacy of smart home devices are affected by JoyLink, a widely used smart home solution. We demonstrate a concrete analysis combined with network traffic interception, source code audit, and binary code reverse engineering to evince that the design of smart home solution is error-prone. We argue that if the security and privacy issues are not considered, devices using the solution are inevitably vulnerable and thus the privacy and security of smart home are seriously threatened.
智能家居的概念推动着家居设备从传统模式向联网模式的升级。制造商通常利用大型IT公司(如亚马逊、谷歌)发布的现有智能家居解决方案来帮助构建智能家居网络，而不是从头开始开发智能设备。智能家居解决方案提供SDK (software development kit)和相关管理系统等组件，促进智能家居设备的开发和部署。尽管如此，第三方sdk和管理系统的参与使这些设备的工作流程变得复杂。如果不仔细评估，复杂的工作流程通常会导致侵犯消费者和制造商的隐私和安全。在本文中，我们说明了JoyLink，一个广泛使用的智能家居解决方案是如何影响智能家居设备的安全和隐私的。我们结合网络流量拦截、源代码审计和二进制代码逆向工程进行具体分析，以证明智能家居解决方案的设计容易出错。我们认为，如果不考虑安全和隐私问题，使用该解决方案的设备不可避免地会受到攻击，从而严重威胁智能家居的隐私和安全。

We analyze the security practices of three smart toys that communicate with children through voice commands. We show the general communication architecture, and some general security and privacy practices by each of the devices. Then we focus on the analysis of one particular toy, and show how attackers can decrypt communications to and from a target device, and perhaps more worryingly, the attackers can also inject audio into the toy so the children listens to any arbitrary audio file the attacker sends to the toy. This last attack raises new safety concerns that manufacturers of smart toys should prevent.

Many physical processes today are augmented with computerized control. Everything ranging from homes to cities are being digitally connected to each other, and to software. Although these connections have resulted in many useful benefits, malicious entities have exploited this new Internet of Things (IoT) to cause damage. In this talk, I'll briefly discuss recent results in securing these emerging IoT systems. I will also outline a few open questions in the field.

Smart homes include hundreds of devices that generate messages, and communicate with each other and the world outside the home, to provide a highly functional, optimized and personalized environment for residents. A secure and reliable event logging system is an essential component of smart homes with a wide range of applications such as fault detection, forensics and accounting. Existing smart home IoT frameworks are cloud-based and privacy of fine-grained log data is a real concern. In this paper we propose a host-based conceptual framework for storing and processing data in smart homes, analyze security requirements of such environments and design a forward secure event logging system that satisfies these environments. We give an overview of our implementation of a message (event) logging system for a typical home, and present efficiency evaluation of our cryptographic design.

The Internet of Things (IoT) devices have expanded into many aspects of everyday life. As these smart home devices grow more popular, security concerns increase. Researchers have modeled the privacy and security threats for smart home devices, but have yet to fully address the problem of unintended user access within the home. Often, smart home devices are purchased by one of the family members and associated with the same family member's account, yet are shared by the entire home. Currently most devices implement a course-grained access control model where someone in the home either has complete access or no access. We provide scenarios that highlight the need for exible authorization control and seamless authentication in IoT devices, especially in multi-user environments. We present design recommendations for IoT device manufacturers to provide fine-grained access control and authentication and describe the challenges to meeting the expectations of all users within a home.

Internet of Things (IoT) is an integral part of application domains such as smart-home and digital healthcare. Various standard public key cryptography techniques (e.g., key exchange, public key encryption, signature) are available to provide fundamental security services for IoTs. However, despite their pervasiveness and well-proven security, they also have been shown to be highly energy costly for embedded devices. Hence, it is a critical task to improve the energy efficiency of standard cryptographic services, while preserving their desirable properties simultaneously. In this paper, we exploit synergies among various cryptographic primitives with algorithmic optimizations to substantially reduce the energy consumption of standard cryptographic techniques on embedded devices. Our contributions are: (i) We harness special precomputation techniques, which have not been considered for some important cryptographic standards to boost the performance of key exchange, integrated encryption, and hybrid constructions. (ii) We provide self-certification for these techniques to push their performance to the edge. (iii) We implemented our techniques and their counterparts on 8-bit AVR ATmega 2560 and evaluated their performance. We used microECC library and made the implementations on NIST-recommended secp192 curve, due to its standardization. Our experiments confirmed significant improvements on the battery life (up to 7x) while preserving the desirable properties of standard techniques. Moreover, to the best of our knowledge, we provide the first open-source framework including such set of optimizations on low-end devices.

In this paper we identify new threats to drones in an effort to have a better public discussion of realistic attacks that vendors need to take into consideration when designing their products. In particular we study in detail the security of a new drone family (U818A) released in 2016, which is quickly becoming a best-selling brand, and is re-purposed and sold by a variety of drone vendors. We implemented and tested several attacks and considered privacy issues (e.g., remotely accessing someone else's drone to take video or images of a private setting), security issues (e.g., stealing a drone mid-flight), and safety issues (e.g., taking down a drone operated by someone else). We finish the paper by recommending basic steps to improve the security of drones.

Many of today's Internet of Things (IoT) devices are vulnerable due to the large amount of overhead incurred when their operating systems are patched against emerging vulnerabilities. In addition, legacy IoT devices are no longer supported by their manufacturers, leaving customers with unpatched devices that can be easily exploited by attackers. Thus, there is an urgent need for a solution that provides a lightweight and low-cost mechanism for preventing exploitation of vulnerable IoT devices. In this paper, we propose an innovative cloud-based framework for protecting IoT devices. The proposed framework consists of a cloud service and a designated IoT security appliance. The security appliance controls the network traffic flowing to and from the vulnerable device and verifies that it does not violate a set of rules, represented by a vulnerability mitigation policy, that have been derived and synthesized by the cloud service from public corpora of Common Vulnerabilities and Exposures (CVE). We demonstrate how the proposed solution can be applied as a cost-effective solution capable of preventing exploitation of vulnerable IP cameras as part of a prominent botnet attack called Mirai.

While the Internet of Things (IoT) becomes increasingly popular and pervasive in everyday objects, IoT devices often remain unprotected and can be exploited to launch large-scale distributed denial-of-service (DDoS) attacks. One could attempt to employ traditional DDoS defense solutions, but these solutions are hardly suitable in IoT environments since they seldom consider the resource constraints of IoT devices. This paper presents FR-WARD which defends against DDoS attacks launched from an IoT network. FR-WARD is an adaptation of the classic DDoS defense system D-WARD. While both solutions are situated near the attack sources and drop packets to throttle DDoS traffic, FR-WARD utilizes the fast retransmit mechanism in TCP congestion control to minimize resource penalties on benign IoT devices. Based on our analysis and simulation results, FR-WARD not only effectively throttles DDoS traffic but also minimizes retransmission overhead for benign IoT devices.
