METHOD AND ELECTRONIC DEVICE FOR MANAGING DIGITAL KEYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18100251 titled 'METHOD AND ELECTRONIC DEVICE FOR MANAGING DIGITAL KEYS
Simplified Explanation
The abstract describes a method for managing keys to access multiple services using an electronic device. Here are the key points:
- The method involves transmitting a certificate of a secure domain (SD) in the device to multiple service providers (SPs).
- The application installed on the device receives certificates from each SP and signed data from a specific SP.
- The application authenticates the signed data using the SP's certificate and obtains an encrypted key from it.
- The SD decrypts the encrypted key using its private key.
- The decrypted key is stored in a specific instance of the SD corresponding to the SP.
Potential Applications
- This method can be applied in various scenarios where an electronic device needs to securely manage keys for accessing multiple services.
- It can be used in mobile devices, IoT devices, or any other device that requires secure access to different services.
Problems Solved
- This method solves the problem of securely managing keys for accessing multiple services on an electronic device.
- It ensures that the keys are transmitted and stored securely, reducing the risk of unauthorized access to the services.
Benefits
- The method provides a secure way to manage keys, ensuring the confidentiality and integrity of the keys.
- It simplifies the process of accessing multiple services by securely storing the keys in the device.
- The use of certificates and encryption enhances the security of the key management system.
Original Abstract Submitted
Provided is a method, performed by an electronic device, of managing keys for accessing a plurality of services. The method includes transmitting, by a secure domain (SD) in a secure area of the electronic device, a certificate of the SD to a plurality of service providers (SPs); receiving, by an application installed in the electronic device, a certificate of each of the plurality of SPs from the plurality of SPs; receiving, by the application, first signed data from a first SP among the plurality of SPs; authenticating, by the application, the first signed data by using a certificate of the first SP received from the first SP and obtaining an encrypted key of the first SP from the first signed data; decrypting, by the SD, the encrypted key of the first SP by using a private key of the SD; and storing the decrypted key of the first SP in a first instance corresponding to the first SP among a plurality of instances of the SD.
