Google will stop trusting certificates from two certificate authorities, Taiwan-based Chunghwa Telecom and Budapest-based Netlock, due to concerning behavior observed over the past year.
Certificate authorities like Chunghwa Telecom and Netlock provide digital certificates for encrypting traffic and certifying the authenticity of sites, having significant control over web security.
Chrome security team observed compliance failures and lack of progress in response to incident reports, leading to the decision to remove trust from these certificate authorities.
Continued public trust in these certificate authorities is no longer justified based on the aggregate factors and risk they pose to internet security as highlighted by the Chrome security team.
