If you want to see raised eyebrows, just say “unbreakable crypto”. Yet everyone assumes their use of crypto is “unbreakable”. Security experts know it’s safe to reject “unbreakable systems” out of hand, but they often rely on the unbreakability of security protocols day in, day out.
I wrote about the ROCA vulnerability yesterday. It affects Infineon security chips used in TPMs and smart cards. While it is easy to identify TPM modules and computers using them, smart cards are more difficult.
Looking back, we can find many examples of errors in the algorithms used to create encryption keys. Not very many of them, however, were found in chips designed and sold as high-security devices for email signing, verifying software integrity, VPN access, or citizen e-ID cards.
Is it really possible to design an encryption system, which is as strong as its strongest link? There is never a straight “yes” answer to this question, but we are now as close as one can get.
We have all heard about hackers stealing huge user databases with passwords as they are tempting bounties. FT, Guardian and many others create a new kind of reward – their internet encryption keys via CDNs – services speeding up web traffic.
While implementing features of the certificate planner, we have added a few handy features to the KeyChest spot checker as well. It is now much more than just a tool to check when a website certificate expires.
Public cloud providers have absolute control over our data, applications, everything we do on their cloud platform. Independent key management lowers users’ risk exposure and as such is in the interest of cloud providers. Well, Amazon AWS has different thoughts.
From supercomputers to IoT – processors (or chips) are everywhere. Computer chips protecting our privacy and security would first travel the world to get designed, fabricated, and personalized. Even if we had an unbreakable encryption algorithm, it may be defeated by its manufacturing. Let’s exploit superpowers and their influence to create a practical unbreakable encryption.
We decided for OpenVPN to build secure connections to our Private Spaces. We braced for difficulties, but that was only the beginning. The point of this post is that integration testing does make a difference. And that OpenVPN is a very nice tool!
