"home grown encryption scheme" seems to imply Zoom is rolling its own crypto, which is tremendously foolish.<p>That isn't exactly the case, per the same article. More Zoom is choosing a poor choice among other choices, of implementing AES:<p>"Furthermore, Zoom encrypts and decrypts with AES using an algorithm called Electronic Codebook (ECB) mode, “which is well-understood to be a bad idea, because this mode of encryption preserves patterns in the input,” according to the Citizen Lab researchers. In fact, ECB is considered the worst of AES’s available modes."<p>Bad idea but not "rolling own crypto bad"<p>edit: agree it's bad. this is pointing out inaccuracies in language from tech journalism reporting on security. This continues to be an issue per the miseducation it creates for the general public in infosec concepts, which is already an uphill battle of misconceptions. Since these articles, or AG Barr, are the discussions that actually hit the mainstream, it's an issue that needs to correct.ed Tech journalism, a profession focused on 'getting the facts,' are the direct conduit of this version of miseducation/failure of facts, and should be corrected.
