Management of profiles in an embedded universal integrated circuit card (eUICC)

摘要

Consumer/enterprise and machine-to-machine functions in wireless devices have led to a need for end user consent, security of profile data while permitting remote profile management, and mixed profile types in a shared embedded Universal Integrated Circuit Card (eUICC). User consent is provided by the device or by the eUICC parsing an incoming profile management command and triggering a user prompt on a user interface. Security of profile data while permitting operation of remote profile management commands is obtained by authentication procedures. In some embodiments, control of command influence is also obtained by providing policy control functions at the profile level. Mixed profile types are supported by creating multiple security domains within the eUICC. Authentication is performed on a public key infrastructure (PKI) basis or on a pre-shared symmetric key basis.
