A mimicry defense based algorithm diversification dynamic scheduling mechanism

N etwork space mimicry defense constructs heterogeneous redundant configuration of execution pool through software and hardware diversification technology, and forms multi-mode output vector through scheduler. Although it can provide a point to surface fusion defense mechanism independent of traditional security means, the execution scheduler, which plays a key role, can still sniff or guess through retransmission attack because of its single and static algorithm. The basic principle of the scheduling algorithm is detected to increase the chance of mimicry escape. This paper designs a dynamic scheduling mechanism with diversified algorithms, which increases the complexity and dynamics of the scheduling mechanism, and can effectively reduce the risk of the scheduler being sniffed. Experimental results show that, compared with the traditional scheduling mechanism, the proposed diversified and dynamic scheduling scheme can significantly reduce the risk of the scheduler being attacked, and further improve the security of the mimicry defense system.
