| Description | We propose a new method for automatic generation of secrecy amplification protocols for wireless sensor networks, utilizing evolutionary algorithms. We were able to rediscover all published protocols for secrecy amplification we are aware of, and found a new protocol that outperforms the existing ones. An alternative construction of secrecy amplification protocols with a comparable fraction of secure links to that of the original ``node-oriented'' approach was also designed. This new construction exhibits only linear (instead of exponential) increase of necessary messages when the number of communication neighbours grows. This efficient protocol can significantly reduce the sensor battery power consumption because of the decreased message transmission rate. We used a combination of linear genetic programming and a network simulator in this work. |
