Paul Kocher, chief scientist at Cryptography Research in San Francisco, said in a recent interview that somebody in the business of making HDCP-compatible devices, who had access to at least 50 individual device keys, would have been able to reconstruct the master key by analyzing “mathematical similarities” in the individual device keys. That was a vulnerability in the technology, Kocher said, that was bound to be exploited.
