Cryptographic Protocols for CrypTool
Skowronek, Ondřej ; Zelený, Jan (referee) ; Henzl, Martin (advisor)
This work is focused on cryptographic protocols and their implementation in the CrypTool. Goal of this work is to settle which cryptographics protocols are appropriate to implement and to find the way how to implement them most illustratively and usably for educational purposes.  These protocols were chosen according to the work assigment: Dining Cryptograhpers, Coin Flippin and Zero-Knowledge. As other appropriate protocols were added:  Yao´s Millionaire Problem and Oblivious Transfer. Detailed concept of chosen protocols and their implementation process are described in this work.
Oblivious transfer
Mach, Martin ; Tůma, Jiří (advisor) ; Krajíček, Jan (referee)
This work examines the part of an asymmetric cryptography called an oblivious transfer. Our goal is to bring a comprehensive overwiew about particular variants of an oblivious transfer and to describe construcions of these variants. A component of the work is an introduction of definitions needed for proving the security of protocols which implements the schemes. We are examining the security of protocols in a semi-honest model. There is informatively explained Rabin's oblivious transfer, but we mainly focused on so-called 1-2, 1-n and m-n alternatives of an oblivious transfer. We mention at least one scheme for each alternative, which we have proven that it is secured. Powered by TCPDF (www.tcpdf.org)
