Sensor networks typically consist of a very large number of nodes with no centralized supervision. As a result, sensor networks are highly prone to an enormous number of logical and physical attacks. These attacks vary from eavesdropping on sensitive information, imputing inaccurate information, to the unintentional failure of nodes as in Denial of Service (DoS) attacks. Many approaches have been...
Still, the security problems remain one of the major barriers somehow preventing the complete utilization of wireless sensor networks (WSN) technology. Securing the communication channel through encrypting messages sent between nodes grow to be a must. Message encryption using the public key cryptosystems [1] in WSN is infeasible due to its constrained resources. A random key pre-distribution scheme...
Collecting information from open and possibly hostile environments makes the wireless Sensor Network (WSN) vulnerable to different types of security threats [1]. To provide secure communications for the WSNs, all messages have to be encrypted with a secret key. Message encryption using the public key cryptosystems [2] in WSN is not applicable due to sensor's constrained resources. A random key pre-distribution...
