Hi guys,

I'm looking for a pdf copy of Encyclopedia of Cryptography and Security (the editors: Henk C.A. van Tilborg, ‎Sushil Jajodia). Perhaps someone could share it, if you have it saved. I would appreciate any reference too, because I need it for my dissertation proposal (High-Speed Cryptography and Cryptanalysis). Also this one: Cryptology and network security : 5th international conference, CANS 2006 Suzhou, China, December 2006 : proceedings (though it's not an obligatory resource).

Can't you use Google for your research?
