Among of Security schemes for Wireless Sensor Networks (WSNs), key management is challenging issue to ensure security of applications. The key management is to establish the required keys between nodes which exchange data. Also, key revocation scheme is the required part of the key management. Among of key revocation schemes, the KeyRev is securer than previous schemes, because it depends on using session key which based on personal key share distribution in network. However, the KeyRev did not consider about duration of session and analysis of diverse attack models.
