TPM compliance study
A TPM compliance study at the HGI institute for IT-security (Ruhr-University Bochum) show that some of the studied TPMs are not fully compliant with the TCG standard, due to some bugs.
The study is interesting, but somewhat misleading in certain aspects. As an example, AES, DES and 3-DES are not required to be supported by the standard, so I am unsure why they appear in the table. The TCG compliance tests are only checjing the existance of seven known TPM bugs as far as I understand from the report.
