• PKI Decentralization: Proposed Approaches to Security Improvement

      After introduction at the dawn of the Internet, public key infrastructure (PKI) has gone through several iterations of changes and updates, but it still remains the traditional methodology for encrypting data and securing communication. PKI supports privacy and protection of data communication between browsers and servers, but it requires implicit trust from a single entity or entities chain called a certificate authority (CA) which has led to a breakdown in confidence. Through the years, having one root entity to control the way private keys are issued to the public has showed that it can cause major complications with transparency and security.

      In this article, we will once again dive deeper into the problems of the current system and consider the solutions being developed that can overcome existing shortcomings.

    • DPKI: Addressing the Disadvantages of Centralized PKI by Means of Blockchain



        Digital certificates are one of the most commonly known auxiliary tools that help protect data across public networks. However, the key disadvantage of this technology is also commonly known: users are forced to implicitly trust certification authorities which issue digital certificates. Andrey Chmora, Technology and Innovations Director at ENCRY, suggested a new approach for building a Public Key Infrastructure (PKI) to eliminate the existing disadvantages using the distributed ledger (blockchain) technology.
        Let's begin with the basics.

      • DPKI: устраняем недостатки централизованной PKI при помощи блокчейна



          Ни для кого не секрет, что один из общераспространенных вспомогательных инструментов, без которого невозможна защита данных в открытых сетях, — это технология цифровых сертификатов. Впрочем, не является секретом и то, что главный недостаток это технологии — безусловное доверие к центрам, выпускающим цифровые сертификаты. Директор по технологиям и инновациям компании ENCRY Андрей Чмора предложил новый подход к организации инфраструктуры общедоступных ключей (Public Key Infrastructure, PKI), который поможет устранить существующие в настоящее время недостатки и который использует технологию распределенного реестра (блокчейна). Но обо всем по порядку.
