Abstract: A method and a device for encrypting/processing the data in an FLT(Flash Translation Layer) are provided to prevent a user from easily understanding information included in the data even if the user extracts the data from a flash memory. An FTL(105) searches more than one page of a flash memory(107) for storing the data if writing the data is requested from a controller(101). The FLT encrypts the requested data by generating a page key corresponding to each searched page according to a predetermined encryption function such as one-way hash function and stores the encrypted data to each searched page when the searched page supports encryption. The FTL stores the requested data to each searched page when the encryption is not supported in the searched page.
Abstract translation: 提供了用于加密/处理FLT（闪存转换层）中的数据的方法和装置，以防止用户即使用户从闪速存储器中提取数据也能够容易地理解包含在数据中的信息。 如果从控制器（101）请求写入数据，则FTL（105）搜索闪存（107）的多于一页用于存储数据。 FLT通过根据诸如单向散列函数的预定加密功能生成与每个搜索页面相对应的页面密钥来加密所请求的数据，并且当搜索页面支持加密时将加密数据存储到每个搜索页面。 当搜索页面中不支持加密时，FTL将所请求的数据存储到每个搜索页面。

Abstract: A system for balancing workload in a distributed computing network is provided to process a plurality of tasks efficiently at the same time in one P2P(Peer-to-Peer) distributed computing network without modifying developed programs by balancing all grinders to use a brewer equally. A distribution center(300) manages a brewer list including brewers(100a-100d) found in the distributed computing network, assigns a session ID when a session ID assignment request is received from a grinder(200), and transmits an available brewer list including the brewers assigned to the grinders by assigning the equal number of brewers to a session assigned to all grinders when a brewer assignment request is received from the grinder. The grinder forms more than one sub task for distributed processing, requests assignment of the session ID/brewers needed for processing the sub task, and requests to the brewers to process the sub task by setting the session with the assigned brewers. The brewer reports a possible service environment periodically to the distribution center, sets up the session by a request of the grinder, and processes the sub task and reports a processing result to the grinder when a sub task processing request is received.

Abstract: A device and a method for deleting a data file depending on backup of a data file are provided to delete the data file in a mobile terminal after checking the backup of the data file by informing a user of the backup of the data file when the data file is deleted. A memory(102) stores at least one data file and includes a backup information table(104) storing backup information of the data file. A controller(100) outputs the checked backup information through a display unit(110) by checking backup of the requested data file through the backup information table when a user requests deletion of the data file. The controller updates the backup data file to the backup information table. The controller checks whether a backup time point is before a modification time point by checking the modified data file is the backup data file when the user requests modification of the backup data file. The controller modifies the backup information in the backup information table to represent that the data file is not backed up when the backup time point is before the modification time point.
