Performance Analysis of Multiple Key Management Schemes in Wireless Sensor Network
نویسندگان
چکیده
Wireless Sensor Network (WSN) is frequently exposed to attackers. The data transmission in secure channel enhances the data confidentiality. This paper discusses multiple schemes with different approaches. Periodic key updating becomes a main point in the design of each scheme. The key updating enhances the security level because of the difficulties added in the network cracking. The performance of each scheme is discussed to show the drawbacks of the public ideas used in the design of these key management schemes. One of these drawbacks is the drawback in the mathematical use of the modular function to generate a shared key between the two parties. This drawback is used in the new schemes and it is illustrated in a numerical example in this paper. The results show also the preference of key updating with each packet to the other discussed schemes.

The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...

Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
