Trusted Blockchain – What are the security solutions for Blockchain?

Decentralized management of multi-actor confidence

Because of the growing interest for crypto-currencies, especially Bitcoin, the underlying technology Blockchain has become a subject of interest that matters.

The potential benefits of the Blockchain, contrary to what is usually thought, are more than just financial: they extend into plenty of domains such as IoT, government, healthcare, retail, manufacturing, energy, supply chain, and education.

Why blockchain?

Blockchain technology is revolutionary and even considered as a disruptive innovation. It consists of a distributed digital ledger that cannot be corrupted: it can keep records of transactions – and not only financial ones. Blockchain and distributed ledgers bring decentralized trust, making possible for companies that do not particularly trust each other, but have common interests, to work together.

Beyond the buzz, a reality!

Atos relies on this technology to move forward and lead this revolution: reduce fraud in retail, increase transparency in supply chains, build and reinforce trust in nascent or empirical relationships with consumers and suppliers. Atos provides additional security and access rights management based on its long term experience in cybersecurity (Digital Identities, Digital Signatures, Hardware Security Modules & Smartcards), while keeping the sovereignty of company data with regards to companies’ clients.

Consortium Trusted Blockchain Security

Consortium Blockchains

Atos can support companies to adopt this new technology to enable decentralized trust and simplify the communication between partners. This is done by creating consortium of companies with a shared business goal. Only authenticated companies with the right credentials can access and participate in these consortia.

Data Control

Data can be written, but only readable by the emitting company which can decide later, whether or not this information has to be shared with one or more other companies in the consortium. Moreover, some access rules can be implemented to govern the interactions of participants with the blockchain.

Identity Management for IoT - Trusted blockchain security

Identity Management

Unlike most of public Blockchains which are based on anonymity, Atos developed a data governance utility plugged on Hyperledger private and permissioned blockchain solution.
Identity is managed by security tools such as Smart Card, PKI and HSMs.

Business Experiences

Business Experience Blockchain

  • Atos was involved with PRO BTP, a French social protection group, in order to implement a POC that runs on the Ethereum Blockchain, for the secure repository and traceability of document deposit.


  • Atos works with the IRT SystemX Technology Research Institute and companies including car manufacturers, insurance companies and energy providers to set up private blockchain networks which can fight against fraud in car maintenance records, and offer a decentralized energy marketplace. A specific research interest concerns the role of Blockchain technologies, including consensus algorithms, for the Internet of Things security.


  • Atos also developed a data privacy and governance layer on the private Blockchain Hyperledger that demonstrates our expertise on this ecosystem.
