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.
Claims17
A method of communication in an electronic device, comprising:
- detecting a request for establishing a call session with an external device;
- generating a new security key based on a preset security key for the external device;
- determining the generated new security key as a current security key for the external device;
- establishing the call session based on the current security key;
- and
- determining a trust level for the external device based on a number of times that call sessions between the electronic device and the external device are established,
- wherein determining the trust level comprises:
- determining whether the preset security key for the external device exists in a memory;
- when the preset security key for the external device exists in the memory;
- comparing a preset threshold with a count indicating that the number of times that call sessions between the electronic device and the external device are established;
- setting the trust level to a first level when the count is greater than the threshold;
- setting the trust level to a second level when the count is equal to or smaller than the threshold;
- and
- when the preset security key for the external device does not exist in the memory, setting the trust level to a third level, and
- wherein the second level is lower than the first level, and the third level is lower than the second level.
An electronic device, comprising:
- a communication circuitry;
- a memory;
- and
- at least one processor operatively coupled to the memory, configured to:
- detect via the communication circuitry a request for establishing a call session with an external device,
- generate a new security key based on a preset security key for the external device,
- determine the generated new security key as a current security key for the external device,
- establish the call session based on the current security key, and
- determine a trust level for the external device based on a number of times that call sessions between the electronic device and the external device are established,
- wherein determining the trust level comprises:
- determining whether the preset security key for the external device exists in a memory,
- when the preset security key for the external device exists in the memory;
- comparing a preset threshold with a count indicating that the number of times that call sessions between the electronic device and the external device are established,
- setting the trust level to a first level when the count is greater than the threshold,
- setting the trust level to a second level when the count is equal to or smaller than the threshold, and
- when the preset security key for the external device does not exist in the memory, setting the trust level to a third level,
- wherein the second level is lower than the first level, and the third level is lower than the second level.
