Chaos Mapping-based Key Pre-distribution Scheme
Zhihua Bao · Communications technology · 2010
A novel key pre-distribution scheme for Wireless Sensor Networks (WSNs)—CMKP(Chaos Mapping based Key Pre-distribution) is proposed.In CMKP,the integer chaos mapping is introduced to generate the chaos sequence with good randomness and self-correlation property.The sensor nodes only need to keep the ID number of some keys in the key pool.In addition,CMKP improves the method for computing the session key.The performance analysis indicates that without increasing the communication overhead,CMKP not only raises the connection probability but also enhances the security of WSNs.
