Lightweight Three – Factor Authentication and Key Agreement Protocol for Internet – Integrated Wireless Sensor Networks
Abstract
Lightweight Three – factor Authentication and Key Agreement Protocol for Internet-integrated Wireless Sensor Networks. Wireless Sensor Networks (WSNs) will be integrated as one of the components of the Internet of Things into the future Internet and will become globally addressable by any Internet-connected entity.
Despite this integration’s great potential, it also brings with it new threats, such as exposure of sensor nodes to Internet-based attacks.In this context, to enable end-to-end secure communication, lightweight authentication and key agreement protocols need to be in place. Amin et al. recently.Suggested a mutual authentication protocol of three factors for WSNs.
However, we identified several flaws in their protocol. We found that their protocol suffers from a loss attack on smart cards where the user identity and password can be guessed using brute force techniques offline.
Conclusion
Lightweight Three-factor Authentication and Key Agreement Protocol for Internet-integrated Wireless Sensor Networks. IoT is an emerging technology that focuses on security and authentication in IoT.We analyzed the main approaches to the design and use of IoT lightweight authentication protocols.
Symmetric key infrastructure schemes are fast, secure and do not consume a great deal of processing power, but require complicated key management, while public-key infrastructure schemes have flexible key management but consume a great deal of computational time and memory space.
