论文摘要
最近的研究表明，在资源约束IoT设备中使用高斯或二项式感应矩阵的基于压缩感测（CS）的计算安全方案很容易受到仅密文的攻击。尽管基于CS的完美安全方案没有这种漏洞，但完美安全方案的实际实现是具有挑战性的，因为它需要一个额外的安全渠道来传输测量规范。在本文中，我们通过掩盖了删除其他安全渠道的需求，从而实现了一个完全安全的方案。由于在资源受限的IoT设备中，高斯传感矩阵的产生是不可行的，因此使用线性反馈移位寄存器生成了近似高斯传感矩阵。我们还证明了在实践中提出的完美安全计划的可行性，而没有额外的复杂性。此外，对提出的方案的安全分析进行了，并将其与最新的基于压缩感应的能量混淆方案进行了比较。
Recent study has shown that compressive sensing (CS) based computationally secure scheme using Gaussian or Binomial sensing matrix in resource-constrained IoT devices is vulnerable to ciphertext-only attack. Although the CS-based perfectly secure scheme has no such vulnerabilities, the practical realization of the perfectly secure scheme is challenging, because it requires an additional secure channel to transmit the measurement norm. In this paper, we devise a practical realization of a perfectly secure scheme by concealing energy in which the requirement of an additional secure channel is removed. Since the generation of Gaussian sensing matrices is not feasible in resource-constrained IoT devices, approximate Gaussian sensing matrices are generated using linear feedback shift registers. We also demonstrate the implementation feasibility of the proposed perfectly secure scheme in practice without additional complexity. Furthermore, the security analysis of the proposed scheme is performed and compared with the state-of-the-art compressive sensing based energy obfuscation scheme.
