Q. Develop a completely secure WSN based on the triple key?
Wireless network is the most vulnerable type of network to security attack. Unauthorized access to wireless network is easy. This is because it transmits data over open space. Unauthorized access to wireless network is easy. Wireless also coined new threats and modifies the current information security hazard profile. For example, since communications accrue "through the air" using radio frequencies, the danger of capture is greater than with wired networks. If the message is not encrypted, the attacker can reach it, thereby weakens confidentiality.
Furthermore, Ad hock wireless sensor networks are resource limited to accommodate the traditional computationally intensive cryptographic (such as asymmetric cryptography) and intrusion detection/prevention (IDS/IDPS) security mechanisms. A secure method that addresses the vulnerabilities in WSN nodes is a triple key management scheme using a network, senor, and cluster keys making them secure in commercial and military environments. The triple key management scheme overcomes the weaknesses in the basic random key pre-distribution scheme; the master key based key pre-distribution scheme, and the single key distribution scheme.
Aim:
The aim is to develop a completely secure WSN based on the triple key management scheme that is applicable in hostile environments and able to resist attacks against the WSN. This will be done through three layer of security, which is "pre-key distribution, path key management, and shared key discovery.
