CMLA provides its Client Adopters and Service Providers security services such as key and certificate provisioning mechanisms, certificate status checking, and the overall PKI hierarchy. The CMLA Technical Specification defines the details needed for the deployment of CMLA based products and services. CMLA’s underlying content protection technology is based on the Digital Rights Management (DRM) specifications from the Open Mobile Alliance. This specification supplements but does not replace the OMA DRM specifications.
