摘要：
本文研究了埃朗程序在源代码、抽象语法树、BEAM汇编和BEAM字节码层面的混淆技术，重点探讨了通过复杂化逆向工程、反编译和再编译过程来提升安全性的方法，同时基于实际的埃朗编译器、验证器、加载器和虚拟机行为。本文分类了指令级依赖技巧、基于接收的循环编码、不规则控制流构造、以可变性为导向的性能混淆以及通过动态模块加载启用的自修改代码。一个反复出现的主题是，有效的BEAM混淆往往并非源于任意破坏，而是源于高阶埃朗语义与工具链和运行时接受的低阶执行模型之间的表示间隙的利用。
英文摘要：
This paper studies obfuscation techniques for Erlang programs at the source, abstract syntax tree, BEAM assembly, and BEAM bytecode levels. We focus on transformations that complicate reverse engineering, decompilation, and recompilation while remaining grounded in the actual behavior of the Erlang compiler, validator, loader, and virtual machine. The paper categorizes opcode-level dependency tricks, receive-based loop encodings, irregular control-flow constructions, mutability-oriented performance obfuscation, and self-modifying code enabled by dynamic module loading. A recurring theme is that effective obfuscation in BEAM often arises not from arbitrary corruption, but from exploiting representational gaps between high-level Erlang semantics and the lower-level execution model accepted by the toolchain and runtime.
