US 2018/0018461 A1 · METHOD AND APPARATUS FOR PROTECTING APPLICATION

Abstract

The present invention relates to a method for protecting content of an electronic device, comprising the steps of: enabling a first security module to transmit a data encryption request to a second security module when data requiring security is generated according to the execution of a security application by the first security module in a security storage region of a memory; enabling the second security module to generate an encryption key by using the authentication information included in the data encryption request and to encrypt the data included in the data encryption request by using the encryption key; enabling the second security module to transfer the encrypted data to the first security module; and enabling the first security module to store the encrypted data in the security application.

Dependent claims

A method for protecting an application of an electronic device, comprising:

transmitting, by a first security module, a request for encrypting data to a second security module when security-required data is generated according to a security application being executed by the first security module in a security storage area of a memory;
generating, by the second security module, an encryption key using authentication information included in the data encryption request, and encrypting the data included in the data encryption request using the encryption key;
transferring, by the second security module, the encrypted data to the first secure module;
and
storing, by the first security module, the encrypted data in the security application.

2 more elements

An electronic device comprising:

a memory;
and
a controller,
wherein the controller comprises:
a first security module that executes a security application in a security storage of the memory, and transmits a data encryption request to a second security module when security-required data is generated according to the execution of the secure application;
and
the second security module that generates an encryption key using authentication information included in the data encryption request, encrypts the data included in the data encryption request using the encryption key, and transfers the encrypted data to the first security module,
wherein the first security module stores the encrypted data in the security application.
