1. A method for forming a trust relationship between entities under an embedded Universal Integrated Circuit Card (eUICC) environment, the method comprising:
- receiving, by a first entity, trust information and verification information, wherein the verification information is transmitted from a second entity;
verifying, by the first entity, the verification information of the second entity using the trust information;
authenticating, by the first entity, the second entity by verifying the verification information; and
establishing a secure communication channel between the first entity and the second entity,wherein the first and second entities include at least one of an eUICC, one or more Subscription Managers (SMs), and one or more Mobile Network Operators (MNOs), andwherein the verification information is at least one certificate of the second entity.
