Dear developers, programmers and engineers,

The first version of The Top Image iOS security compiler will be released on March 8, 2018, and we will launch a prize-winning beta test at that time. We hope to invite you to participate!


[Program Introduction] :

Top Image iOS security compiler is the next generation hardening product of top Image virtual machine source protection technology for iOS platform. By compiling the source code through the Top Image iOS security compiler, the object code/executable file can be deeply confused, hardened, and the use of top Image’s original virtual CPU to encrypt the code, any reverse tool can not be directly reverse cracked. Security compilers can be easily integrated into Xcode to provide protection for apps or dynamic/static libraries.

The core function

function

Introduction to the

Code virtualization

Source code is compiled into dynamic DX-VM virtual machine instructions that run on top of the DX virtual machine and cannot be decompiled back into readable source code. (This function is not open for internal testing)

String encryption

All static constant strings (including C/C++ strings and NSString) are encrypted and decrypted at runtime to prevent attackers from conducting static analysis through strings and guessing code logic.

Symbol confusion

All function names, OC class names and method names are confused to eliminate semantics and increase the difficulty of reverse analysis.

The logical confusion

The control flow of the original code is segmented, disrupted and hidden, flower instructions are inserted, the code logic is complicated without affecting the original function, and the difficulty of being cracked is greatly reduced.

advantage

· Unique virtual machine source protection technology in the industry, which is several orders of magnitude more difficult to crack than open source obfuscation technology

· After hardening, IPA and static library with Bitcode can be packaged

· Rich configuration parameters can be flexibly configured according to the needs of the project

· Seamless integration with Xcode, easy to use

· The tool is localized and there is no risk of disclosure when bitcode(almost the same as source code) is uploaded to a third party platform

. Local integration, unlimited use
