Abstract: Internet of things (IoT)-based trust aware B-tree Goldwasser-Micali cryptographic node authentication technique is developed for secured communication in 5G mobile networks with higher accuracy. The IoT-TBTGMCNA technique includes three phases namely key generation, distribution and node authentication. In key generation phase, the keys are generated and distributed for the mobile nodes by using Goldwasser-Micali cryptographic algorithm. After key generation, Goldwasser-Micali encryption algorithm encrypts the key and transmitted to child node. After getting the encrypted key, the child node decrypts key with its ID using Goldwasser-Micali decryption algorithm. Whenever the sender mobile node needs to authenticate the receiver, it sends the request to that particular node. When both keys are similar, then mobile node is termed as authenticated node. With the authentic node, the data transmission is performed to achieve secure communication. The comparative analysis achieves improved performance in terms of minimum computation overhead and higher authentication accuracy as well as security level than the other well-known methods.

Keywords: 5G; wireless networks; internet of things; IoT; Goldwasser-Micali cryptography; node authentication; B-trees.
