Position-Verification in Multi-Channel Models
Huajun Zhang, Zongyang Zhang, and Zhenfu Cao
Abstract
We propose an collusion-attack-resistant position-verification protocol in a new model called multi-channel model. In the multi-channel model, there are lots of communication channels. When a player picks a random channel and sends a short message over it, the message might slip by an adversary with high probability if the adversary does not know the channel beforehand. This idea is motivated from the spread spectrum communication techniques. We adopt it to solve the position-verification task. Adding different constraints into the multi-channel model, we make three sub-models: receiving-constrained multi-channel model, sending-constrained multi-channel model and cover-constrained multi-channel model. Our position-verification protocol is secure under all of these sub-models with appropriate parameters.
Note: Welcome any discussion on this topic.
