摘要：In not distant future, the Wireless Sensor Networks (WSN) iswidely used in many applications likemilitary and civil domains.The wireless sensor networks are always deployed in hostile andpervasive environment.Security is major worry in wirelesssensor network. The traditional network security methods are notsuitable forwireless sensor networks because of limited resource.Several Key management and establishment schemes havebeensuggested to provide light weight ciphers. The key managementschemes play an important role in wireless sensornetworks toachieve security. Basically, keymanagement includes two aspects: key distribution and key revocation. Keydistribution refers to the task of distributing secretkeys between communicating parties to provide secrecy andauthentication. Key revocation directs to the task of securelyremoving compromised keys. By revoking all of the keysof a compromised sensor node, node can be removed from thenetwork. As compared to key distribution, key revocationhas received very little attention.In this paper a survey of key management schemesin wireless sensor networks hasbeen executed.
