Ultra-High Reliable Multi-AP Cooperation Utilizing Securely Compressed Channel Status Information for Next Generation Wireless LANs

As Wi-Fi 8 standardization aimed at ultra-high reliability (UHR) has progressed, advanced communication technologies are being actively studied. As hyper-connected intelligent network environments have become more common, ensuring high throughput and low latency in wireless communication networks, as well as seamless communication for real-time applications, has become increasingly important. Typically, in Wi-Fi 8, the multi-AP cooperation technique in which multiple APs work together to transmit data has been actively discussed. This has the advantage of improving communication coverage by performing coordinated transmission with an optimized transmission technique by exchanging control information by multiple APs. However, there is a limitation in that it can cause an overhead problem in the network and a security threat that exploits channel state information in that the control information transmitted and received between devices increases together. However, conventional technologies do not consider the problem of a malicious attacker manipulating channel state information to reduce communication efficiency or the problem of increasing overhead. Therefore, this study proposes a Bitmap Compression-based Secure Channel Management Mechanism (BC-SCMM), a hash-based bitmap compression method to minimize overhead due to control information in an intelligent communication environment. According to the experimental results, BC-SCMM reduced latency by $74.12 \%$ and energy consumption by $105.19 \%$ while ensuring the confidentiality of channel status information compared to the non-channel management mechanism (NCMM).
