Comparing (almost) identical papers – a steganographic exercise

As those keen on encryption and decryption will know, there are quite a few documented methods by which ‘secret’ messages can be concealed within apparently straightforward-looking chunks of text. Indeed, the original meaning of the word ‘Steganography‘ is simply ‘concealed writing’. For example, two blocks of text which at first glance appear alike can have […]

Garbling obliviousness and authenticity (cryptographically)

Lack of security in electronic communications can either be seen as a problem, or an asset, depending on your viewpoint. Either way, it’s a given that a great deal of high-end cryptographic research is currently underway. Accounts of recent progress can be found via Professor Mihir Bellare’s web page at the Department of Computer Science […]


The best-named scientific conference of the year, so far, is the GeoCrypt conference: The GeoCrypt 2009 conference will take place at Hôtel Fleur d’Épée (Le Gosier), about 6km from Pointe-à-Pitre, Guadeloupe, French West Indies [from April 27-May 1]… The purpose of the conference is to bring together researchers from arithmetic geometry and from cryptography and […]
