Wireless Sgx =link= Page

Traditional RAN uses purpose-built, locked-down appliances (think ASICs and FPGAs). 5G changed the game with vRAN (virtualized RAN), running baseband processing on commodity x86 servers. This is great for cost and agility, but terrible for security:

This report analyzes how SGX technology is utilized to enhance security in wireless environments. By creating hardware-isolated "enclaves," SGX allows wireless systems to process sensitive data (such as encryption keys, user credentials, and location data) in a protected memory region, rendering the data inaccessible even if the host operating system or kernel is compromised. wireless sgx

While robust, SGX is not infallible. Several high-profile vulnerabilities have impacted the feasibility of "Wireless SGX." By creating hardware-isolated "enclaves

Throughput note: Early SGX had overhead (~5-15%), but with (larger enclave memory) and TDX (confidential VMs), wireless workloads now achieve near line-rate. wireless workloads now achieve near line-rate.
