Abstract：The self-organizing network，dueto itscharacteristics of flexible networkingand communication completion without fixed facilities，has been widelyused in scenarios such asemergencyrescueand military confrontation，However，itssecurity lacks suffcient protection.Adressing the potential interference from external attackers during thenetwork construction phaseofself-organizing networks，ahigh-reliability，low-costaccess authenticationalgorithmis designed.Toreduce thecommunication payloadoverhead introduced by thealgorithm， improvementsare madetothe traditional message digest5（MD5）encryptionalgorithm，reducing the lengthof the encrypted results.Inorder to reduce theauthentication time overhead and resist transmission errors introduced by the algorithm，enhancementsare made to the traditional“thre-way hand-shake”mechanism，introducinga retransmision mechanism to reduce transmission errors，and an alert mechanism to identify atackers.Through simulationand theoreticalanalysis，itcan bedemonstrated thatthe proposedalgorithm is capableof resisting transmission errors between nodes，identifying potential attackers，and maintaining low communication payload and authentication time overhead.It can be widely applied in various self-organizing network systems.
