Wearable computing has great potential to revolutionize the future of everyday lives. Nonetheless, communications among wearable devices may lead to significant security concerns, given that wearable devices often capture sensitive personal information and may have to operate in hostile environments. In this article, we systematically study the security issues in wearable communications. Specifically, we start with an overview of security concerns for typical wearable applications. Then we review the state-of-the-art research and state-of-the-practice development for security in wearable computing in both industry and academia. At last, we propose a layered adaptive security architecture, with the aim of preventing adversaries from "breaking through" all layers of security by simply compromising one particular security measure, and discuss possible mechanisms to enhance the security of each layer.
