The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our experimental evaluation demonstrates that StormShield effectively prevents gNB resource exhaustion, identifying and blocking MUEs with an average detection accuracy of 97.6% within 106.5 ms from the beginning of the attack.

C2weakest assumption

The fingerprinting remains reliable under real-world mobility, varying traffic loads, and different UE implementations beyond the two gNB setups tested in the OTA testbed.

C3one line summary

StormShield fingerprints and blocks malicious UEs in O-RAN 5G RANs to prevent RRC signaling storms, achieving 97.6% detection accuracy within 106.5 ms on an OTA testbed with OAI and commercial hardware.
