This serial number check can be done using a simple local database at the Resource (website). Things get a bit more complicated if there are many Resources (say different websites), and you want to prevent credential re-use across all of them. The typical solution outsources serial number checks to some centralized service (or bulletin board) so that a user can’t use the same credential across many different sites.

The threat extends beyond accidental errors. When AI writes the software, the attack surface shifts: an adversary who can poison training data or compromise the model’s API can inject subtle vulnerabilities into every system that AI touches. These are not hypothetical risks. Supply chain attacks are already among the most damaging in cybersecurity, and AI-generated code creates a new supply chain at a scale that did not previously exist. Traditional code review cannot reliably detect deliberately subtle vulnerabilities, and a determined adversary can study the test suite and plant bugs specifically designed to evade it. A formal specification is the defense: it defines what “correct” means independently of the AI that produced the code. When something breaks, you know exactly which assumption failed, and so does the auditor.，推荐阅读体育直播获取更多信息
