Abstract: An electronic device includes a memory and a processor. The memory includes a data partition, a key storage partition, and a key backup partition. The processor operatively connected to the memory. The processor is configured to generate an encryption key with respect to at least one data folder generated in the data partition to store the encryption key in the key storage partition. The processor is also configured to store a backup encryption key equal to the encryption key, in the key backup partition. The processor is further configured to store an integrity file including a checksum of the encryption key in the key backup partition.

Abstract: An apparatus and a method for processing an application in a mobile terminal are provided. The method includes loading, by a bootloader upon system booting, a kernel, determining whether the kernel is modified, creating, when the kernel is modified, kernel verification information indicating a custom kernel, encrypting the kernel verification information, and sending the encrypted kernel verification information, activating, by a kernel handler, the kernel, and receiving the kernel verification information from the bootloader, and forwarding the kernel verification information, decrypting, by a rooting detector, the kernel verification information into kernel status information and delivering the kernel status information when a specified Application Programming Interface (API) is invoked, and invoking, by an application handler, the API when an application is executed and controlling an execution of the application when the kernel status information indicating the custom kernel is received.

Abstract translation: 提供了一种在移动终端中处理应用的装置和方法。 该方法包括在系统启动时由引导加载程序加载内核，确定内核是否被修改，创建内核，修改内核，指示自定义内核的内核验证信息，加密内核验证信息，以及发送加密的内核验证 信息，由内核处理程序激活内核，以及从引导加载程序接收内核验证信息，以及转发内核验证信息，通过生根检测器将内核验证信息解密为内核状态信息并提供内核状态信息 当指定的应用程序编程接口（API）被调用并且在应用程序执行时由应用程序处理程序调用API，并且当接收到指示定制内核的内核状态信息时控制应用程序的执行。
