基于分层快速盲解卷积的安全大规模IoT

Secure Massive IoT Using Hierarchical Fast Blind Deconvolution

Gerhard Wunder, Ingo Roth, Rick Fritschek, Benedikt Groß, Jens Eisert

摘要:

物联网,特别是触觉互联网,对安全概念提出了重大挑战。在这项工作中,我们引入了一个新的概念,安全的大规模访问。我们的方法的核心是一个快速和低复杂度的盲解卷积算法,探索一个双线性和分层压缩感知框架。我们表明,盲解卷积有两个吸引人的特点:1)没有必要协调的导频信号,所以即使在用户活动的冲突的情况下,信息消息可以解决。2)由于所有单独的信道是并行恢复的,并且通过假设的信道互易性,所测量的信道熵用作公共秘密,并且用作每个用户的加密密钥。我们将概述该方法的基本概念,并详细描述盲解卷积算法。仿真结果表明,该算法能够同时恢复信道和消息。它们还表现出该方案在经济恢复和秘密容量之间的内在权衡。

英文摘要:

The Internet of Things and specifically the Tactile Internet give rise to significant challenges for notions of security. In this work, we introduce a novel concept for secure massive access. The core of our approach is a fast and low-complexity blind deconvolution algorithm exploring a bi-linear and hierarchical compressed sensing framework. We show that blind deconvolution has two appealing features: 1) There is no need to coordinate the pilot signals, so even in the case of collisions in user activity, the information messages can be resolved. 2) Since all the individual channels are recovered in parallel, and by assumed channel reciprocity, the measured channel entropy serves as a common secret and is used as an encryption key for each user. We will outline the basic concepts underlying the approach and describe the blind deconvolution algorithm in detail. Eventually, simulations demonstrate the ability of the algorithm to recover both channel and message. They also exhibit the inherent trade-offs of the scheme between economical recovery and secret capacity.
