Today, the editor will take you to understand what the UE4 program and resource encryption protection scheme is. The knowledge points in the article are introduced in great detail. Friends who think it is helpful can browse the content of the article together with the editor, hoping to help more friends who want to solve this problem to find the answer to the problem. Let's follow the editor to learn more about "what is the UE4 program and resource encryption protection scheme".

UnrealEngine4 shell encryption. Virbox Protector

Solve code disassembly and anti-dump code, solve software piracy and algorithm plagiarism.

Unreal engine 4 is a complete set of game development tools created by game developers to develop games. From two-dimensional mobile platform games to host platform masterpieces, Unreal engine is a pure C++ engine designed for high performance. Its advanced CPU/GPU performance analysis tools and flexible renderer allow developers to efficiently complete a high-quality VR experience. The main code logic of UE4 is located in the project EXE and the resource file pak. Think deeply that virbox Protector can protect the code in exe from disassembly, while encrypting pak resource files to protect intellectual property rights in the software from being embezzled.

Encryption scheme:

Virbox Protector shell protection:

Virbox protector shelling tool is a set of high-strength automatic protection encryption tools developed by ourselves, which creatively introduces pre-analysis and automatic optimization engine, which effectively solves the problem of security and performance balance when virtualizing code protection. It integrates automatic code migration, confusion, shell encryption and data encryption, which can achieve extremely high protection intensity without programming.

With the use of thinking Elite 5 encryption lock, the authorization file is written into the encryption lock, and the important algorithms of the software are transplanted to run in the encryption lock. Elite 5 lock supports RSA1024/2048, ECC192/256/384, AES128/192/256, DES/TDES, SHA1/SHA256 standard international algorithms, lock execution speed 50MIPS, communication speed 300KB/S, can ensure the safety and high speed of the lock algorithm, so as to ensure the overall speed and experience of the game.

Cooperate with soft lock or cloud lock to reduce the cost of developers on the premise of ensuring high security. The cloud lock is used in the case of networking, without hardware, and has high ease of use and convenience. Soft locks can be used offline, without hardware, binding hardware fingerprints, you can control the number of devices bound.

DS Protector resource protection

Protect all kinds of resource files, such as pictures, video, audio, etc., to protect resources from being stolen.

Security technology: l virtual machine shell: elite 5 shell protection tool, innovative introduction of pre-analysis and automatic optimization engine, effectively solve the problem of security and performance balance when virtualizing code protection.

L fragmentation code execution: using the code extraction technology in its mature shell, a large amount of code is extracted and executed in a secure environment after encryption confusion, so as to minimize the dependence on the underlying technology and functions of the encryption lock. at the same time, a large number of large-scale transplantation ensures higher security.

L Virbox encryption compilation engine: it integrates security functions such as compilation and obfuscation. Due to the intervention in the compilation phase, the optimizable space is incomparable with general virtualization technology, and the degree of confusion of code and variables has been fundamentally improved.

L anti-black engine: built-in R0 core state anti-black engine, (anti-black database) countermeasure based on behavior characteristics. Precise attack on debugging, injection, memory modification and other behaviors, from passive to active protection.

Features: l security: a number of independent research and development of encryption technology to ensure the security of UE4 program encryption

L flexibility: you can use hardware encryption locks, cloud locks or soft locks, and you can also control the time-limited and time-limited sales of software.

L convenience: custom shell, one-click encryption, no need to change the code, fast encryption development!

L stability: 99.95% stability, allowing developers to focus on business development without worries

Final result:

Effectively prevent decompilation or disassembly of formats such as EXE

Confusion and virtual machines protect the key functions of developers and reduce the speed of human flesh restoration code logic.

Do not reduce the number of game frames, and even increase the number of game frames in some cases.

Driver level anti-debugging, second kill common debugger (IDA Pro/WinDbg/OllyDbg/X64Dbg).

Code on-demand decryption, only the relevant algorithm is called to decrypt in memory, do not call no decryption. * cannot decipher all the code at once!

Comparison of the results before and after encryption: OllyDbg debugging failure and additional failure on 1.PC.

2.Cheat-Engine failed to read memory (need new anti-triad engine support)
