摘要： An obfuscation evaluation method which sufficiently evaluates an obfuscation performed on a program. The obfuscation evaluation method includes: a step of executing an obfuscated code module produced by obfuscating an original code module of a program, and generating a trace output file by logging a result of the execution; and a step of identifying the degree of obfuscation of the obfuscated code module by evaluating the trace output file.

摘要： A program obfuscator of the present invention divides a target program into a plurality of blocks and determines program instructions allocated according to an input/output relation between the blocks, in order to diffuse and allocate the program instructions for calculating a value of secret information in various places of the program. More specifically, with regard to a variable for calculating the secret information transferred to and from the blocks, a value of the variable when outputted from a block is equalized to a value of the variable when inputted to a next block. A random variable conversion instruction is added to each of the blocks so that a value of the variable when outputted from each block is in a range of a value expected as an input to the next block.
摘要翻译：本发明的程序混淆器将目标程序划分为多个块，并根据块之间的输入/输出关系确定分配的程序指令，以扩散并分配用于计算各种秘密信息的值的程序指令程序的地方。更具体地，关于用于计算传送到块的秘密信息的变量，当从块输出时，变量的值在输入到下一个块时与变量的值相等。随机变量指令被添加到每个块，使得当从每个块输出时变量的值在期望作为下一个块的输入的值的范围内。

摘要： It is possible to update and re-seal sealed data having a usability condition of matching with predetermined terminal environment information during a secure boot without rebooting a terminal when a program using the sealed data is updated. An information processing terminal (10) has first sealed data (310, 320, 330) respectively having usability conditions (312, 322, 332) of matching with predetermined terminal environment information during a secure boot and second sealed data (340, 350, 360) respectively having usability conditions (342, 352, 362) of matching with terminal environment information upon completion of the secure boot. Upon completion of the secure boot, the second sealed data is unsealed and the first sealed data is resealed using the unsealed data (341, 351, 361).
