Estonia is upgrading the security of ID cards and digital IDs used by citizens, residents and e-residents. A new certificates update has been developed based on advanced elliptic-curve cryptography, which is more secure and faster than the SSL certificates previously used. From a report: This certificate update will protect users from a potential security vulnerability that the Estonian government announced last month had been identified by a group of security researchers. It has now been confirmed that the vulnerability is contained in software that had previously been installed on the embedded chip used in ID cards around the world, including those issued by Estonia between 16 October 2014 and 25 October 2017. Although the problem is international, minimising the risk and developing a solution has been a top priority for Estonia since the government was informed. However, there has still been no reported incidents of any Estonian digital ID or ID card being misused in the way described by the researchers. Considerable resources and expertise would be required for this so the risk for most people affected has always been low.
