摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating data using instructions as a source of pseudorandom values. Obfuscation is performed by receiving instructions and data and compiling the instructions and the data into an executable file having a text section and a data section. The text section can include instructions and the data section can include data segments. The system obfuscates the data section iteratively by generating a hash of an address for a respective data segment, and based on the hash, identifying a corresponding address in the text section that includes at least one instruction. The system retrieves a mask key from the corresponding address and applies the mask key to the respective data segment, yielding a masked data segment. In one embodiment, integrity verification of obfuscated data is performed without exposing the data in an unprotected state by utilizing multiple mask keys.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating a computer program. A system configured to practice the method identifies a set of executable instructions at a first location in an instruction section of the computer program and identifies a second location in a data section of the computer program. Then the system moves the set of executable instructions to the second location and patches references in the computer program to the set of executable instructions to point to the second location. The instruction section of the computer program can be labeled as _TEXT,_text and the data section of the computer program is labeled as _DATA,_data. The set of executable instructions can include one or more non-branching instructions optionally followed by a branching instruction. The placement of the first and second locations can be based on features of a target computing architecture, such as cache size.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for obfuscating using inlined functions. A system configured to practice the method receives a program listing including annotated functions for obfuscation, identifies an annotated function called more than once in the program listing, and creates an inline control flow structure in the program listing for the identified annotated function, the control flow structure being computationally equivalent to inlining the identified annotated function into the program listing for each occurrence of the identified annotated function. The program listing can include tiers of annotated functions. The system can identify annotated functions called more than once based on an optionally generated callgraph. The system can create inline control flow structures in the program listing in order of annotation importance. The system can identify how many times each annotated function is called in the program listing.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating branches in computer code. A compiler or a post-compilation tool can obfuscate branches by receiving source code, and compiling the source code to yield computer-executable code. The compiler identifies branches in the computer-executable code, and determines a return address and a destination value for each branch. Then, based on the return address and the destination value for each branch, the compiler constructs a binary tree with nodes and leaf nodes, each node storing a balanced value, and each leaf node storing a destination value. The non-leaf nodes are arranged such that searching the binary tree by return address leads to a corresponding destination value. Then the compiler inserts the binary tree in the computer-executable code and replaces each branch with instructions in the computer-executable code for performing a branching operation based on the binary tree.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for binary layout randomization. A system performs binary layout randomization by loading computer code into memory and identifying a section of the computer code to randomize. A loader remaps the section of computer code to a different location in memory utilizing a remapping algorithm. The loader can shuffle sections of code in place or move sections of code elsewhere. The loader patches relative addresses to point to the updated locations in memory. After the system patches the addresses, the system executes the computer code from memory. In one embodiment, the system encrypts the computer code prior to loading the computer code into memory. The loader decrypts the encrypted computer code prior to remapping the section of computer code to a different location in memory. Optionally, the loader can decrypt the encrypted computer code after patching relative addresses.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for executing encrypted computer code. A system configured to practice the method receives a request to execute encrypted computer code. In response to the request, the system identifies a portion of the encrypted computer code for execution and decrypts the portion to yield decrypted computer code. Then the system stores the decrypted computer code in a pool of memory and executes the decrypted computer code from the pool of memory. The system can store the decrypted computer code in the pool of memory based on a randomization algorithm so that identical executions of the encrypted computer code result in selections of different available memory locations within the pool of memory. Related portions can be stored non-consecutively in the pool of memory. The pool of memory can store different portions of decrypted computer code over time.
