Abstract:
An interface method for a measuring device includes: generating, by a portable device, an image including at least one of a measurement result and identification label of the measuring device using a camera; extracting, by the portable device, at least one of the measurement result and identification label of the measuring device from the generated image; and transmitting, by the portable device, the at least one of the extracted measurement result and identification label of the measuring device to an information system for managing measurement data.
Abstract:
A method for operating an electronic device is provided. The method includes executing, by a processor of the electronic device operable in a first mode (e.g. a trusted execution environment (TEE)) or a second mode (e.g. a non-trusted execution environment (NTEE)), wherein the first mode is more secure than the second mode; receiving, by the processor operating in the first mode, data or information related to a first software program stored in a first memory region; and authenticating, by the processor operating in the first mode, at least a portion of the data or information using a second software program stored in a second memory region.
Abstract:
A method and an electronic device are disclosed herein. The electronic device includes a communication unit, a storage unit and at least one processor, which executes the method, including detecting a request for establishing a call session, generating a new security key from a preset security key, renewing the preset security key by setting the generated new security key as a current preset security key, and establishing the call session based on the generated new security key.
Abstract:
A method of operating data security and an electronic device supporting the same are provided. The method includes executing a general Application (App) based on a non-trusted execution module; executing a first trusted App related to the execution of the general App based on a trusted execution module; generating a message by encrypting data generated in the first trusted App; transmitting the encrypted message to the general App; and transmitting the encrypted message to a second trusted App related to the execution of the general App and executed based on the trusted execution module.
Abstract:
A method and apparatus of access control in an electronic apparatus implementing the method are provided. The method of operating an electronic apparatus includes detecting an access request to a resource from an application included in a first area of a memory by a processor of the electronic apparatus, in response to the access request, executing an access control module included in a second area of the memory to calculate a hash value of the application by the processor, determining whether a record exists in the memory, the record corresponding to the hash value and identification information of the application, by executing the access control module by the processor, and allowing access to the resource by the processor when the record exists in the memory.
