保护 Ruby 代码 [英] Protecting Ruby Code

问题描述

我正在使用 Ruby 在带有自定义 Linux 内核的基于 ARM 的嵌入式板上开发一个商业项目.项目和设备的目标工作区是封闭环境，没有以太网、inernet、I/O 设备等……我想保护我的代码/程序，以便；它只能在我让的特定机器上工作(所以；人们不能只是将我的代码/程序复制并粘贴到他们的嵌入式板上并在没有许可的情况下运行它).这可能可以通过机器的 MAC 地址来完成；我对这个问题没有任何经验.我想，只是一个简单的 if(device.MACAddr == "XX:XX....XX") 不会可靠(更不用说人们可以轻松地从我的代码中删除支票).我不能使用一些 ruby​​ 混淆器，这是我通过谷歌找到的，因为；设备不运行 ruby​​-external-C-libraries 或类似的东西，只有纯 ruby​​ 代码.

I'm developing a commercial project on an ARM based embedded board with a custom Linux kernel on it, using Ruby. Target workspace of the project and the device is a closed-environment, no ethernet, inernet, I/O devices etc... I want to protect my code/program so that; it'll only work on the specific machines I let (so; people cant just copy and paste my code/program on to their embedded boards and run it w/o permission). This can probably done with the machine's MAC address tho; I don't have any experience on the subject. I guess, just a simple if(device.MACAddr == "XX:XX....XX") wouldn't be depandable (not to mention people can just easily delete the check from my code). I can't use some ruby obfuscators, which I found thru google, beacuse; the device doesnt run ruby-external-C-libraries or such stuff, only pure ruby code.

所以；你有什么建议，我应该采取什么样的方法?

So; what are your suggestions, what type of approach should I take?

推荐答案

这与 DRM 的问题是同构的.你给了一个人一把锁和那把锁的钥匙，并试图阻止那个人以你不喜欢的方式使用钥匙.

This is isomorphic to the problem of DRM. You're giving a person both a lock and the key to that lock, and trying to stop that person from using the key in a way you don't like.

因此，我建议使用与其他 DRM 用户相同的方法:将您的条款放入许可中，如果他们违反了许可，则可以起诉他们.无论如何，您需要使用法律来执行许可的其他条款.

Therefore, I suggest using the same methods that other DRM users do: put your terms in the license, and sue them if they violate it. You need to use the law to enforce the other terms of the license, anyway.
