摘要：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
