The present disclosure relates to a method and system for enabling IOT security using a decentralized IOT security platform that leverages the advanced communication and blockchain security thread model to protect IOT eco-systems. The platform uses a multi-chain data schema including a device chain and an event chain. The multi-chain data schema uses a time-envelope mechanism to generate an event to connect different device chains and enforce a set of security rules through smart contracts. The method comprising receiving an encrypted block from IOT device with event data and verifying the device signature and identity based on certain rules within the device chain. Further, the method comprising determining access to event chain using previous token, current token and timestamp of the encrypted block and updating the event chain upon access determination. The event chain protects data integrity and confidentiality against malicious packets, unauthorized devices, weak encryption and man-in-the-middle attacks. Link to Full Patent
