Data for: Detection and Defense of Active Attacks for Secret Key Generation Based on Wireless Channels in Static Environment
Description
In static or quasi-static environments, secret key generation (SKG) based on wireless channels is bad random and vulnerable to active attacks. To improve the randomness of the generated secret key, singular value decomposition (SVD) techniques are used to reconstitute equivalent wireless channels in multiple-input multiple-output (MIMO) systems. The eigenvector matrices obtained from the SVD and private pilot, which is generated dynamically from the equivalent wireless channels, are used to detect active attacks by authenticating the sender based on the wireless channels. To defend passive eavesdropping and active attacks, the concept of one time pad is used to generate dynamic private pilot. The proposed SKG scheme based on private pilot and SVD techniques can detect whether the SKG is under man-in-the-middle attack, impersonation attack, signal injection attack, defend passive eavesdropping and active attacks effectively, and obtain higher SKG rate and randomness than the approach via random beam-forming. Theoretical analysis and simulation results demonstrate the above results again.
