Abstract: System and Method for achieving cyber security of Internet of Things (loT) 
devices using embedded recognition token 
ABSTRACT 
The present invention relates to a system and method for achieving cyber security or 
preventing cyber-attacks of Internet of Things (loT) devices in an internet environment. The 
objective of present invention is to solve the anomalies presented in the prior art techniques 
and using advanced technique for authenticating the legitimate communication between 
Internet of Things (loT) devices. The disclosure presents a technique using embedded 
recognition token for authenticating the legitimate use of the Internet of Things (loT) devices 
in an internetwork environment. The use of Internet of Things (loT) devices is increasing with 
the advancement in technology and the feature of Internet of Things (loT) devices for building 
an automatic system. The use of Internet of Things (loT) devices makes most of the system 
automatic and robust in nature. With the increasing use of Internet of Things (loT) devices, 
the cyber attacks to these devices are also increasing day by day. The hackers or attackers can 
intrude the network environment and steal the personal information. The hackers can also 
control these Internet of Things (loT) devices remotely and change the functioning of the 
system built using these Internet of Things (loT) devices. Hence, providing cyber security to 
Internet of Things (loT) devices is an important aspect that need to be dealt with greater 
accuracy and improved performance. The proposed invention uses embedded recognition 
token for legitimate communication between Internet of Things (loT) devices for achieving 
cyber security. The proposed invention discloses a method that provide/issue unique 
embedded recognition token and hash key for each of the plurality of Internet of Things (loT) 
devices. These issued embedded recognition token and hash key are used to authenticate the 
legitimacy of the Internet of Things (loT) devices in the internetwork environment. Suppose 
the first Internet of Things (loT) device need a communication with second loT device, then 
first loT devices sends its embedded recognition token to the second loT device which is used 
to authenticate the first loT device using the hash key. After recognition, the second loT 
device invites the first loT devices to establish communication link between first and second 
loT device along with its embedded recognition token. The first loT device 
recognize/authenticate the second loT device using received embedded recognition token 
and hash key and after recognition, establishes a secure communication link between first 
and second loT devices. The first and second loT devices can perform communication in 
internetwork environment securely using said secure communication link by authenticating 
the legitimacy of both the communicating devices and intruder will not enter within the 
communication. In this way, cyber attacks can be prevented and cyber security can be 
achieved in loT devices with the proposed invention. The proposed method can be applied 
on plurality of loT devices simultaneously within communication environment.
