| A trust anchor is an authoritative entity represented via a public key and associated data. It is used in the context of public key infrastructures, X.509 digital certificates, and DNSSEC. When there is a chain of trust, usually the top entity to be trusted becomes the trust anchor; it can be, for example, a Certification Authority (CA). A certification path starts with the Subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted CA. Path validation is necessary for a relying party to make an informed trust decision when presented with any certificate not already explicitly trusted. Status information for certification paths includes, certificate revocation lists or online certificate status protocol responses.
Rationale for non-applicability:
There is no requirement for a user to authenticate to the mobile application because the operating system has already authenticated the user. Additionally, the scope of the MAPP SRG excludes mobile applications that serve external users and processes. Thus, no external users or processes would authenticate to the mobile application using certificates or otherwise. |
