Encryption algorithms GCMP are also not supported, so is it possible that these vulnerabilities exist on devices with GCMP encryption?

vanhoefm commented 1 year ago

These questions are also covered in the paper. Search for the term GCMP.

According to my understanding, if vulnerabilities are discovered through testing according to the method of this project, whether using CCMP or GCMP, these attacks can be implemented. Is this correct?

vanhoefm commented 1 year ago

Ah, this project specifically tests using CCMP only. There's a good chance that if an implementation is vulnerable when using CCMP (so when this tool says an implementation is vulnerable) that it will also be vulnerable when using GCMP. But the only way to be sure that an implementation is also vulnerable when using GCMP, is to extend this tool to also support GCMP.
