Frequently this ment that 20-25% of comms could be broken quickly with these providing usefull information (known plain text etc) to break any of the harder keys. However anyone capturing the equipment and re-using the design without the required knowledge would end up using a cross section of strong and weak keys on a random basis. Because the NSA was responsible for keying material used by the US then they could ensure the use of the strong keys. One trick they grabbed with both hands in the old days of mechanical cipher machines was to have a large key space where some keys were strong and others weak to very weak in some non obvious manner. This “dual role” would make many people and organisations schitso/paranoid and this has certainly appeared to be the case in the past with the NSA. The problem is “National Security” has a definition as broad as required by those formulating US policy, and this has in the past been used to spy on any company that is trying to do business in the same market as US companies irrespective of if the other entities are US or not (note this is not unique to the US the French openly indicated that they did this many years ago, and many other nations have been caught at it in the past). Like Bruce reiterates over and over again, perfect security is perfectly impossible.įolks should remember that in theory the NSA has two contradictory missions,ġ, Protect the communications of the USA that effect US National Security.Ģ, Gain access and understanding on the communications of other nations and nationals (that are assumed to always effect US National Security). In short, securing communications or data on the internet may be a real trick–if it can be done. There also seems to be an event related to this in 2006.

I don’t know what happened in 2011 that seems to have perturbed the PKI system(s). Microsoft Root CA,, Google, and some other CA’s. Whether it was a MITM or some other attack is not clear (some theories rotate on a BGP exploit).

Remember the adobe certificate hijack event? Previous to that discovery was a Tor project discovery that exposed diginotar that seems to point to a GTE forgery.

Certificates, hashes, and checksums are insufficient methods to determine and match audited source code to the the source control methods, configuration management systems, the build process, and binary distribution. is not well established in the commercial realm.

#ENCRYPTSTICK NSA VERIFICATION#

Verification of cryptographic applications, irrespective of the layer or distribution model. Tags: academic papers, algorithms, cryptanalysis, cryptography, encryption, NSA, Threefish Why was the work done, and why is it being made public? I’m curious. I don’t know anything about the context of this paper. Missing, of course, is any cryptanalytic analysis. And I enjoyed the discussion of requirements. I am always impressed with how the NSA does key schedules. I was most impressed with their key schedule. I was particularly interested in the algorithms’ similarity to Threefish, and how they improved on what we did.

It’s always fascinating to study NSA-designed ciphers.

Both perform exceptionally well across the full spectrum of lightweight applications, but SIMON is tuned for optimal performance in hardware, and SPECK for optimal performance in software.

#ENCRYPTSTICK NSA SOFTWARE#

Each offers excellent performance on hardware and software platforms, is flexible enough to admit a variety of implementations on a given platform, and is amenable to analysis using existing techniques. The aim of SIMON and SPECK is to fill the need for secure, flexible, and analyzable lightweight block ciphers. While many lightweight block ciphers exist, most were designed to perform well on a single platform and were not meant to provide high performance across a range of devices. The NSA has published some new symmetric algorithms:Ībstract: In this paper we propose two families of block ciphers, SIMON and SPECK, each of which comes in a variety of widths and key sizes.
