Abstract
Systems and methods provide a platform for threat information sharing. A method comprises transmitting an access permission request to a blockchain network. The request asks for access to cyber threat information stored in at least one cyber threat information storage system. The information may come from a plurality of organizations. The blockchain network may include a blockchain ledger storing access control information from the plurality of organizations. Upon receipt of a reference to an access permission token generated by the blockchain network using at least one smart contract, a transaction request to the cyber threat information server may be sent. In response to the transaction request including the reference to the access permission token, the requested cyber threat information may be retrieved from the cyber threat information server.
