Today I submitted my diploma thesis to my university.

The thesis summarizes several months of investigation of the Probabilistic Signature Scheme (PSS). Traditionally, RSA signatures are done by hashing and then signing them. PSS is an improved, provable secure scheme to prepare a message before signing. The main focus was to investigate where PSS is implemented and used in real world cryptographic applications with a special focus on X.509.

During my work on that, I also implemented PSS signatures for the nss library in the Google Summer of Code 2010.

The thesis itself (including PDF and latex sources), patches for nss and everything else relevant can be found at
