Abstract

In many self-healing key distribution schemes

the size of sliding window affects both the self-healing capability and the communication overhead.With probability knowledge

the mathematical model is built

which reflects the influence of the size of sliding-window and packet loss rate on the performance of key synchronization

group security association and security service.Then

an adjustment mechanism of sliding window is proposed to adapt to the dynamic change of broadcast links

and a look-up table is utilized to reduce the computation and storage overhead.Simulation results show that the scheme proposed is dynamically adaptive

and guarantees the performance of security service with high probability.Compared with the existing schemes

the proposed scheme greatly reduces the communication overhead

and is more feasible and efficient.Meanwhile

it further promotes the application of self-healing key distribution.
