Can bits of an RSA public key leak information about design and implementation choices such as the prime generation algorithm? We analysed over 60 million freshly generated key pairs from 22 openand closedsource libraries and from 16 different smartcards, revealing significant leakage. The bias introduced by different choices is sufficiently large to classify a probable library or smartcard wit...

Recent experiments using mainly character unigram distributions in authorship attribution tasks are discussed. Results so far indicate efficacy in similarity judgements seemingly good enough for ‘balance of probabilities’ standards, but not yet for proof ‘beyond reasonable doubt’.

In this paper we discuss the SPKI standard as an alternative to the current X.509 and OpenPGP standards. The paper starts with a short history of PKI, and assesses the current state and the various flaws in the X.509 and OpenPGP standards. Then the main part of this paper explains the concepts of SPKI, and discusses how SPKI supports various notions of trust. Finally the paper concludes with an...
