Cybersecurity, for its part, is the set of technical, organizational and legal measures put in place to protect computer systems, networks, connected devices and personal data against malicious attacks, data leaks and acts of cybercrime. Cybersecurity aims to ensure the confidentiality, integrity and availability of digital data, as well as the protection of users’ privacy. It involves the implementation of security policies, risk management processes and IT security tools such as firewalls, antivirus software, intrusion detection systems, encryption systems, digital certificates and security protocols.
Among the emerging technologies used in cybersecurity, blockchain occupies an important place. Blockchain is a technology for storing and transmitting information, enabling the creation of replicated and distributed registers, with no central control body, secured by cryptography, and structured by blocks linked to each other at regular time intervals. The blockchain guarantees the authenticity and traceability of transactions, and eliminates the need for intermediaries and central control entities. As a result, it is a disruptive technology with the potential to revolutionize several sectors where security and transparency are key issues. The future of finance, healthcare data sharing, digital identity management, product traceability, intellectual property, voting management, the energy sector and the arts could all depend on it. Blockchains can be public or private. The best-known public blockchains are those used for crypto-currencies such as Bitcoin and Ethereum. Private blockchains are mainly used in professional and industrial contexts.
ICTs and cybersecurity technologies are interdependent and evolve in a complementary way. As there are many interconnections between these disciplines, it is natural to find them in the same innovation ecosystem.
