アプリケーション間でユーザ情報を安全に転送すること

Japanese Patent JP7086327

B2

The present disclosure describes a system, method, and non-transitory computer readable medium for provisioning multiple instances of a secure communication application on multiple devices. A secure communication application on a first device generates a first set of private keys that are associated with the user and a second set of keys that are associated with the secure communication application executing on the first device. The first set of private keys establishes a set of root identifying keys for the user that are identical for all installations of the secure communication application, while the second set of keys will vary from device to device. In this regard, the first set of root identifying keys must be securely transferred from the first device to any subsequent installations of the secure communication application on one or more second devices. This establishes a high degree of trust since each installation of the secure communication application is linked to the first set of root identifying keys and allows the user to send and receive encrypted communications on multiple devices from the same trusted root keys.
