Two neural network-based models can synchronize its initially different weight vectors by limited steps of single output bit-based mutual learning if only the two models hold a common input space. Such novel weight synchronization property can well be used for secure key exchange over a public communication channel. Itpsilas more suitable for the resource-constraint sensor networks because that the...
Considering the storage characteristics of vector digital geographic data, and taking the advantages of the sensitivity of the initial values and parameters of chaos-based system, a compound chaos-based encryption algorithm was proposed for encrypting vector geographic data here, the algorithm presented a stronger and larger space of key, which overcame some disadvantages of single chaos-based encryption...
This paper discusses the problem of achieving bandwidth and energy-efficient neighborhood group key distributions (NGKD) in tactical wireless sensor networks (TWSNs). We present new techniques that improve NGKD performance while also improving the resilience of TWSNs against attacks that combine node capture with message interception. This is accomplished without introducing additional communications...
