Swiss cyber-security firm Wisekey has integrated its utility token, a blockchain-based asset to be used by drones and robots to secure IoT interactions and to recognise and trust each other, into the Oracle blockchain.

Wisekey’s validation service (the certificate’s validation authority), using its public key infrastructure, analyses Wisetoken digital certificates to recognise and trust the identity of connected machines such as drones and robots when they interact with each other, and mitigate malicious actors and hackers from compromising these interactions.

Wisetokens are sold directly by Wisekey as utility tokens and generate revenue as a hybrid product and service offering. They are not listed on secondary markets and are sold at a fixed price thus are not subjected to price fluctuations.

The validation service provides objects with the ability to send to the validation authority the third party’s public key and the digital certificate for validation. Wisekey checks that the corresponding public key holds a valid Wisetoken and, if so, the identity is verified. To receive the verification, the object making the request must hold at least one Wisetoken in its wallet, which is valid for 12 months or 100 requests.

Wisekey can, over time, adjust the number of utility tokens required to get verified, longevity of the token and entitled verifications per token.

The validation service is used to verify the authenticity of the object’s digital identity in real time, thus ensuring secure use of digital identities for authentication of any object connected to the internet and the activation of attributes such as digital signing, transactions or data transmission.

Wisekey’s platform is blockchain neutral and allows blockchain configurations to benefit by the use of secure private keys instead of public keys currently used. Private keys secure data and transactions, which can be only conducted between authenticated parties, thus making it a viable option for any sort of IoT transaction.

Wisekey’s VaultIC184 secure element consists of a tamper resistant silicon chip, based on a secure microcontroller chip, which can be integrated into a device by its manufacturer.

Wisekey deploys large-scale digital identity ecosystems for people and objects using blockchain, AI and IoT. Its microprocessors secure the pervasive computing shaping today’s IoT. Wisekey IoT has an install base of over 1.5 billion microchips in virtually all IoT sectors. Its semiconductors produce a huge amount of big data that, when analysed with artificial intelligence, can help industrial applications predict the failure of their equipment before it happens.
