Use of Public Key Infrastructure (PKI) to Enhance Privacy Protection and User Trust

Use of Public Key Infrastructure (PKI) to Enhance Privacy Protection and User Trust

The explosion of connected devices and Internet of Things (IoT), and the emergence of new applications have led to the generation of a huge amount of data. Digital transactions are also increasing, and authenticating two entities before exchanging data is a necessity.

Furthermore, recent breaches have shown that data should be enciphered while being exchanged or stored to avoid potential threats and cyber attacks. As a result, public key infrastructure (PKI) appears as a relevant solution to create confidence and trust. PKI providers have extended their associated services to better answer clients’ demands. Moreover, different pricing models are available and PKI platforms are scalable to facilitate the integration and the support of new devices, operating systems, and new applications.

However, digital transformation is gaining momentum and many alternatives are already available. Blockchain is a new way to design services. The innovative algorithm makes the deployment of new authentication and validation process easy.

As a result, revenue generated by the PKI technology could be impacted by the emergence of disruptive services and innovative start-up companies. Additionally, regions that are not using PKI significantly could be attracted to directly adopt these new services to decrease dependence on third parties and certificate authorities. This approach simplifies the value chain, and also decreases the price for authentication, verification, and validation of the digital transaction and associated identity.
