Totally unrelated but I noticed this the other day when downloading the latest version of winzip.
WinZip 9.0 supports 128- and 256-bit key AES encryption, which provide much greater cryptographic security than the traditional Zip 2.0 encryption method used in earlier versions of WinZip.
Is AES Encryption a standard?

Yup. There's even free implementations floating around online.

Wow, great to see that we have all levels of expertise interested in at least contributing... granted, some of it isn't useful to those with more expertise, but at least they are trying, right? :)
Sony has decided to use security measures that are all either standard, or are a publicly available service from a company (if you have money). However, the setup is done in such a way that Sony still 'has all the keys'. Understanding the AES and RSA encryption systems, Verisign's signing process, and RSA Security's BSAFE technology documents are the best places to start right now. These are all 'open' technologies (i.e. not free as in speech, but not hidden in the mists of trade secrets), so knowing them and their strengths will give you insight into the approach Sony took with the PSP.
