Guardtime wins contract to protect UK nuclear fleet

Guardtime has been given the job of protecting the UK's nuclear power stations, flood defence systems, and electricity grid from cyberattack, using its Keyless Signature Infrastructure blockchain based on hash-function cryptography.

The UK infrastructure deal is a partnership with Future Cities Catapult, a UK-based centre of excellence for smart city innovation.

The security specialists use Blockchain systems remove single points of attack by distributing permanence of data over trusted, private networks of validators, or trustless, public ones made up of many nodes like Bitcoin.

The company combines cybersecurity experts with US military backgrounds, and technology innovators in Estonia.

Matthew Johnson, chief technology officer of Guardtime said these industrial applications are to ensure the management and control platforms and networks for nuclear power sub-systems have integrity.

Johnson told IBTimes UK: "We can continuously monitor the integrity of the control platform so that operators who have access to management software see a picture of the system as true and correct against an approved configuration baseline, that there is an absence of compromise or malware in the software applications and configuration data responsible for operations."

Guardtime created Keyless Signature Infrastructure (KSI), which is built into an industrial blockchain and which signs any and all data across a system and allows independent verification of time, location and authenticity for any moment in history.

The partnership, in a statement, said it will address the concerns highlighted in a recent report by think tank Chatham House, which highlighted cybersecurity concerns around nuclear power plants; the industry harbours a "culture of denial" about the risk of cyberattacks with many failing to protect themselves against digital attacks, it said.
