Abstract:
1. A migration apparatus for transferring data protected within a first terminal device to a second terminal device, comprising: a non-transitory memory device that stores a program; and a processing device that executes the program and causes the migration apparatus to operate as: wherein before transmitting the secret data to the second terminal device, the control unit (i) receives, from the first terminal device, a minimum evaluation level required of a destination of the secret data by the first terminal device, (ii) receives, from the second terminal device, an evaluation level of the second terminal device, (iii) judges whether the evaluation level of the second terminal device is lower than the minimum evaluation level, and (iv) sends the secret data to the second terminal device only if the evaluation level of the second terminal device is no lower than the minimum evaluation level, wherein the minimum evaluation level is an Evaluation Assurance Level that is to be fulfilled by the destination of the secret data, and is defined based on Common Criteria according to a requirement by the first terminal device, and wherein the evaluation of the second terminal device is an Evaluation Assurance Level that is given to the second terminal device, and is defined based on Common Criteria.
