摘要：A wireless network consisting multiple (ranging
from a few hundreds to thousands) nodes which are sparsely
dispersed and have dedicated sensors for monitoring,
recording, detecting environment and gathering environmental
data (e.g. light, sound, temperature, pressure, wind speed,
directions, motion, etc.) is usually known as a Wireless Sensor
Network (WSN). These nodes are self-organizing and are not
controlled by a central administrator. The wide adoption and
deployment rate of WSN is as a result of the processing power,
wireless communication and the sensing technology that the
WSN possesses. The numerous advantages this network holds
has led to its growth. As the deployment and acceptability of
WSN increases, the vulnerability to attacks is increasing hence
the need for effective security mechanisms. Encryption has
proven to be a reliable way of data protection hence its
adoption in the improvement of the security level in WSNs.
Identifying suitable encryption mechanism for WSNs has
proven to be a challenge due to the limited amount of energy,
computation capability and storage resources of the sensor
nodes. This paper addresses the security challenges in wireless
sensor networks and effects of cryptography in the bid of
improving its security.
