webid working on windows? with client cert…and NO prior registration?

See http://aspnet.codeplex.com/SourceControl/changeset/view/1acc79fbc998#Samples%2fNet4%2fCS%2fWebApi%2fClientCertificateSample%2fCustomCertificateMessageHandler.cs Hmm. While this shows client certs driving a server-side guard, I’m not sure the SSL Client authentication mechanism is being used. And, webid semantics are restricted to client certs used in the client authentication procedure of the SSL … Continue reading

certgen, using windows oauth2.0’ microsoft consent

In contrast to the MVC4 apparatus/templates, the openlink websso plugin for windows (live) weeo seems to directly use an OAUTH service – which is not simply a bridge to ws-fedp. However, using IE10, we cannot actually make ourselves a cert. … Continue reading

reed muller, monomials, and encoding matrices

Having played with a generator of RM style “repetition codes” in Turing’s own machine, we get to see a more analytical treatment of RM itself – in which the 2 codewords are not just bit strings… but representation of linear … Continue reading

Defcon and colossus

Fun to see an homage to colossus on the lanyard of the defcon badge, this year. So what do the base 32 chars spell?

shannon vs tunny. Who won?

Prof Forney does a good job teaching engineering, skilling students in engineering math while he is at it. At the end of the day, the engineer is a designer – working with parameters. What matters is to understand the role … Continue reading

“not very interesting”–says Forney about an infinite series of 0s. Not true!

At 13:10, in http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-451-principles-of-digital-communication-ii-spring-2005/lecture-notes/lecture-15-trellis-representations-of-binary-linear-block-codes/ Prof. Forney sounds a little bored discussing the trellis version of a binary code generator. He cheers up after describing how (all my words and concept), now “bombe like” one can look at the “central” element … Continue reading

webid to bombe (or rather the other way around)

The theory of computer science is rich – and even richer when you stick the computer science department in the middle of a long-established statistics department, focused on bayesian  methods (making a Department of Computer Science and Statistics). Why does … Continue reading

dyadic models in number theory–would NSA *want* to suppress results?

http://terrytao.wordpress.com/2007/07/27/dyadic-models/ If NSA and similar agencies wanted the veto on certain results of number theory research (historically), in what areas would the veto apply? It has to be those results that reduce complexity – having moved the problem from the … Continue reading

semantic web promotes winner take all; condensates and bosons

which is fine if you are in the lead, consuming 50% of the worlds resources. No wonder folks keep working on making the semantic web take off. http://en.wikipedia.org/wiki/Bose%E2%80%93Einstein_statistics what I like about the semantic web is that we get a … Continue reading

compactness to limiting

The more we study 1930s research topics, the more we can read into Turing’s “on permutation groups” manuscript – and see the parallels. We see Turing taking a unit interval – obvious in one form to any 12 year old … Continue reading

signin crypto principles

see https://yorkporc.wordpress.com/2011/04/29/nsa-signin-via-cryptome/ Now we understand that the turing bombe “unwrapped” the enigma rotor substitutions, the signin rotor cage looks more normal. The separator with its “mixed wire” substitution is like an unwrapped reflector. One sees 8 auto-powered rotors and that … Continue reading
