The Swiss Government PKI is the centrepiece of the federal trust services and is used whenever confidentiality must be specifically ensured. The PKI keys are trusted because the PKI is designed and operated according to very specific rules. The focus is on compliance with these rules, which is why they are consistently checked by accredited bodies. The PKI is thus certified annually and the trustworthiness of the keys is documented.
The Swiss Government PKI is one of three certified Swiss providers who meet the stringent requirements for these certifications (ESigA, ETSI).
