1. A method for forming a trust relationship between an embedded Universal Integrated Circuit Card (eUICC) and a Subscription Manager-Secure Routing (SM-SR) connected to the eUICC via a network, the method comprising:
- a verification information generating step of generating, by the eUICC, a first verification information based on a first trust information that is transferred or shared;
a verification information exchanging step of transmitting, by the eUICC, the first verification information to the SM-SR as information to be used by the SM-SR to authenticate the eUICC based on the first trust information, and receiving a second verification information from the SM-SR, the second verification information being generated by the SM-SR based on a second trust information that is transferred or shared;
and a verification information verifying step of authenticating, by the eUICC, the SM-SR by verifying the second verification information received from the SM-SR based on the second trust information.

9. An embedded Universal Integrated Circuit Card (eUICC) configured to form a trust relationship with a Subscription Manager-Secure Routing (SM-SR), the eUICC being connected to the SM-SR via a network, the eUICC comprising:
-
a verification information generator configured to generate a first verification information based on a first trust information that is transferred or shared; a verification information exchanger configured to transmit the first verification information to the SM-SR as information to be used by the SM-SR to authenticate the eUICC based on the first trust information, and to receive a second verification information from the SM-SR, the second verification information being generated by the SM-SR based on a second trust information that is transferred or shared; and a verification information verifier configured to authenticate the SM-SR by verifying the second verification information received from the SM-SR based on the second trust information. - View Dependent Claims (10, 11, 12)

13. A method for forming a trust relationship between entities connected to each other in a communication system, the method comprising:
-
generating, by a first entity among the entities, first verification information based on a first trust information of the first entity, the first trust information being transferred or shared, and generating, by a second entity among the entities, a second verification information based on a second trust information of the second entity, the second trust information being transferred or shared; exchanging, by each of the first and second entities, the generated first and second verification information by transmitting the generated first and second verification information respectively to the other of the first and second entities; and authenticating, by the first entity, the second entity by verifying the second verification information transferred from the second entity based on the second trust information and authenticating, by the second entity, the first entity by verifying the first verification information transferred from the first entity based on the first trust information so as to form the trust relationship between the first and second plurality of entities.

14. A method for forming a trust relationship, the method comprising:
-
a step of forming a trust relationship between an embedded Universal Integrated Circuit Card (eUICC) and a first Subscription Manager-Secure Routing (SM-SR) connected to the eUICC via a network, wherein the SM SR generates a first verification information based on a first trust information that is transferred or shared and the first SM-SR generates second verification information based on a second trust information that is transferred or shared, the eUICC transmits the generated first verification information to the first SM-SR, the first SM-SR transmits the generated second verification information to the eUICC, and the eUICC authenticates the first SM-SR by verifying the second verification information received from the first SM-SR based on the second trust information, and the first SM-SR authenticates the eUICC by verifying the first verification information received from the eUICC based on the first trust information; a step of forming a trust relationship between the first SM-SR and a second SM-SR connected to the first SM-SR via the network, wherein the first SM-SR generates a third verification information based on a third trust information that is transferred or shared, the second SM-SR generates a fourth verification information based on a fourth trust information that is transferred or shared, the first SM-SR transmits the generated third verification information to the second SM-SR, the second SM-SR transmits the generated fourth verification information to the first SM-SR, and the first SM-SR authenticates the second SM-SR by verifying the fourth verification information received from the second SM-SR based on the fourth trust information; and a step of forming a trust relationship between the second SM-SR and a Subscription Manager-Data Preparation (SM-DP) connected to the second SM-SR via the network, wherein the second SM-SR generates a fifth verification information based on a fifth trust information that is transferred or shared, the SM-DP generates a sixth verification information based on a sixth trust information that is transferred or shared, the second SM-SR transmits the generated fifth verification information to the SM-DP, the SM-DP transmits the generated sixth verification information to the second SM-SR, the second SM-SR authenticates the SM-DP by verifying the sixth verification information received from the SM-DP based on the sixth trust information, and the SM-DP authenticates the second SM-SR by verifying the fifth verification information received from the second SM-SR based on the fifth trust information. - View Dependent Claims (15, 16, 17)
