摘要： Oblivious checking of a digital good is performed by identifying a plurality of key instructions within a function of a digital good. Each key instruction is an instruction that possibly modifies a register or a flag. An extra instruction is then inserted into the function for each of the key instructions. The extra instructions each correspond to one of the key instructions and modify a register in a deterministic fashion based on the corresponding key instruction. A set of inputs to the function are then identified that result in different valid computation paths in the function being taken. A checksum for the function is then generated by using a mapping function which maps the contents of the register to the set of inputs.

摘要： A portion of a digital good is selected to be used as a substitution box (S-box) in encrypting at least another portion of a digital good. The digital good being encrypted can be the same digital good, or alternatively a different digital good, than the digital good from which the portion used as an S-box is obtained. During the encryption process, the S-box is used to substitute values of the portion being encrypted with new values (a process also referred to as “scrambling”).

摘要： A method, apparatus, and article of manufacture for providing secure and opaque type libraries to automatically provide secure variables within a programming module. A system for providing secure and opaque type libraries to automatically provide secure variables within a programming module. The system includes an OTL selection module, an OTL substitution module, an OTL type library database, a compiler module; and a linker module to create an executable processing module. The OTL selection module randomly selects or generates one of the possible variable obfuscation functions for each declared secure variable. The OTL substitution module substitutes the separate instance of the selected variable obfuscation function for every reference to the declared secure variable. The OTL type library database receives queries from the OTL selection module a database to identify of possible variable obfuscation functions applicable for the variable type corresponding to the declared secure variables.

摘要： A cryptographic technique that not only provides fast and extremely secure encryption and decryption but also assures integrity of a ciphertext message. This technique involves, during message encryption: generating, in response to an incoming plaintext message, an intermediate stream--such as by chaining the message, wherein a predefined portion of the intermediate stream defines a message authentication code (MAC); inserting an encrypted version of the MAC into a predefined portion of a ciphertext message; and generating, in response to the intermediate stream and the encrypted MAC, a remainder of the ciphertext message such that the remainder exhibits a predefined variation, e.g., a pseudo-random sequence, also contained within the encrypted MAC. Decryption proceeds in essentially a reverse fashion. By extending the sequence across the remainder of the ciphertext, any subsequent change to the ciphertext would likely destroy the continuity of the sequence otherwise residing throughout the remainder of the ciphertext. During decryption, any violation to the integrity of the ciphertext can be readily detected by decrypting the MAC contained in the ciphertext and comparing it, for any discrepancies, against a MAC generated from recovered plaintext.

摘要： Implementation of graph-based tamper resistance modeling for software protection is described. In one implementation, paths of execution of a program are modeled as a graph having nodes and edges. A tamper resistance tool receives an input program code corresponding to the program and generates a tamper-resistant program code using integrity checks. Values for the integrity checks are computed during program execution and are compared to pre-computed values to determine whether a section of the program has been tempered with. Values of the integrity checks may be accessed at any point in time during execution of the program.

摘要： Cyclic verification of code integrity is applied to an object by identifying multiple segments of the object. Each segment is separated into multiple blocks, and a message authentication code (MAC) value of each of these segments is computed. The computed module MAC values are then incorporated into selected ones of the multiple segments (referred to here as “checker segments”), which may also have their MAC values incorporated into other checker segments. A new MAC value for each of the checker segments is then calculated. A new block is added to each of the checker segments that results in restoring the MAC value of the checker segment back to its original value. Thus, the checker segments can be subsequently verified based on the MAC values stored in other segments.
摘要翻译：通过识别对象的多个段来对代码完整性进行循环验证。每个段被分成多个块，并且计算每个这些段的消息认证码（MAC）值。计算出的模块MAC值然后被合并到多个段中的选定的一个（这里称为“检验器段”），其也可以将它们的MAC值合并到其他检验器段中。然后计算每个检查器段的新MAC值。每个检查器段都添加一个新的块，导致检查器段的MAC值恢复到原始值。因此，随后可以基于存储在其他段中的MAC值验证检验器段。
