    Automatic proof of resistance of denial of service attacks in protocols by Bo MENG, Wei HUANG, De-jun WAND, Fei SHAO

    Published 2012-03-01
    “…First,the applied PI calculus was extended from two aspects:attacker contexts and process expression,then from the view of protocol state,the protocols were modeled with the extended applied PI calculus and a automatic method of proof of resistance of denial of service attacks based on theorem proof with first order theorem prover ProVerif was presented,finally resistance of denial of service attacks in JFK protocol and IEEE 802.11 four-way handshake protocol were analyzed.The results obtained are that JFK protocol is resistance of denial of service attack and IEEE 802.11 four-way handshake protocol is not.At the same time a new al of service attack in IEEE 802.11 four-way handshake protocol was found.The methods to prevent resistance of denial of service attacks in IEEE 802.11 four-way handshake protocol were proposed.…”

    Performance analysis and optimization of cooperative spectrum sensing with relay by Mei-ling LI

    Published 2013-09-01
    “…An object based cooperative spectrum sensing scheme with relay was proposed,and the fact that the channel condition from SU to SR has an important influence to system performance was proved.In view of this,an optimized cooperative spectrum sensing scheme with best relay(optimized BRCSS) was proposed,in which the best secondary relay was selected by considering both the channel condition from SU to SR and SR to FC.Finally,an adaptive cooperative spectrum sensing scheme with best relay (A-BRCSS) was proposed further to save the system expense considering more practical application occasion,where,SU could adaptively decide whether the relay’s cooperation was needed by its reporting channel condition.Both analysis and simulation results show that,the better sensing performance can be achieved by the optimized BRCSS scheme compared with the tradit l cooperative spectrum sensing scheme with best relay.The nearly best sensing performance can be obtained by the proposed A-BRCSS scheme.…”
