摘要： Techniques for replacing ROM-based (Read-Only Memory) DLLs (Dynamic Link Libraries) in a Windows CE type embedded operating system such that the target DLL is replaceable by the hook DLL, and the target DLL is callable by the hook DLL but not callable directly by any other applications after loading of the hook DLL. The techniques enable replacement irrespective whether the hook DLL and the target DLL have the same name and irrespective of which DLL is loaded first. The techniques change the file name of the target DLL in a list of loaded DLL modules by a trusted program that executes in the full kernel mode.
摘要翻译：在Windows CE类型嵌入式操作系统中替换基于ROM（只读存储器）DLL（动态链接库）的技术，使得目标DLL可由钩子DLL替换，并且目标DLL可由钩子DLL调用，但不是在挂载DLL后，可以直接由任何其他应用程序调用。无论钩DLL和目标DLL是否具有相同的名称，并且无论首先加载哪个DLL，这些技术都能够进行替换。该技术通过在完整内核模式下执行的可信程序来更改加载的DLL模块列表中目标DLL的文件名。

摘要： A method for encrypting a file using a combination of an electronic device and a protection communication-enabled (PCE) wireless device is provided. The method includes using an encryption/decryption engine executing on the electronic device to encrypt a first flag string, which is a binary string stored in a header of the file, with a digest value to create an encrypted flag string. The digest value is associated with the PCE wireless device, which is a device having a transmission application program installed thereon for enabling interaction between the PCE wireless device and the encryption/decryption engine. The method also includes encrypting at least a portion of the file using the digest value and a first password provided by a user, thereby generating an encrypted file that includes an encrypted version of at least a portion of the file, the encrypted flag string, and the first flag string.
摘要翻译：提供了一种使用电子设备和保护通信使能（PCE）无线设备的组合来加密文件的方法。该方法包括使用在电子设备上执行的加密/解密引擎来加密作为文件头部存储的二进制字符串的第一标志字符串，并具有摘要值以创建加密的标志字符串。摘要值与PCE无线设备相关联，PCE无线设备是其上安装有传输应用程序的设备，用于实现PCE无线设备与加密/解密引擎之间的交互。该方法还包括使用摘要值和由用户提供的第一密码对文件的至少一部分进行加密，从而生成加密文件，该加密文件包括文件的至少一部分的加密版本，加密的标记串和第一个标志字符串。

摘要： A computer network includes endpoint computers and a file history server with a file history database. An endpoint agent in an endpoint computer detects file access events in the endpoint computer and generates file activity data for storage in the file history database. The file activity data may include file access event information of file access events and file information of files involved in the file access events. The endpoint agent may consult the file history database to locate a duplicate of a damaged file in another endpoint computer, and restore the damaged file using the duplicate. A backup and restore program may also consult the file history database to determine whether or not to make a backup copy of a file involved in a file access event.

摘要： A mobile telephone includes an application processor, internal memory, an external memory card, a backup software module and a restore software module. User data is stored in the internal memory. The backup software module detects changes in the user data, resulting in modified user data. The modified user data is stored onto the external memory card. When the user data is erased from the internal drive or the wireless device needs to be reset the restore software module reads the modified user data from the external memory card and writes the modified user data back onto the internal memory. In this fashion, any modified user data is not lost when the wireless device is reset.

摘要： Known malicious Android applications are collected and their functions are extracted. Similarity values are calculated between pairs of functions and those functions with a low similarity value are grouped together and assigned a unique similarity identifier. A common set of functions or common set of similarity identifiers are identified within the applications. If at least one function in the common set is determined to be malicious then the common set is added to a blacklist database either by adding functions or by adding similarity identifiers. To classify an unknown Android application, first the functions in the application are extracted. These functions are then compared to the set of functions identified in the blacklist database. If each function in the set of functions is present (either by matching or by similarity) in the group of extracted functions from the unknown application then the unknown application is classified as malicious.

摘要： An ANDROID application package (APK) file for an application is repackaged into a secured APK file to protect a Dalvik executable (DEX) file of the application. The DEX file is encrypted to generate an encrypted DEX file that is included in the secured APK file along with a stub DEX file. The secured APK file is received in a mobile computing device where the stub DEX file is started to start a wrapper Activity. The wrapper Activity replaces an APK class loader of a mobile operating system of the mobile computing device with a decryptor class loader. The decryptor class loader decrypts the encrypted DEX file to recover the DEX file, and loads classes of the DEX file into a Dalvik virtual machine. The original Activity of the application is then started to provide the functionality of the application in the mobile computing device.
