5th Workshop on Current Trends in Cryptology (CTCrypt’2015)

5th Workshop on Current Trends in Cryptology (CTCrypt’2015)
June 06–08, 2016 (Russia, Yaroslavl)

Organized by

  • Russian Technical Committee for Standardization TC 26 «Cryptography and security mechanisms»
  • Academy of Cryptography of the Russian Federation
  • Steklov Mathematical Institute of Russian Academy of Science

The scope of the workshop includes, but is not limited to the:

  • Design and analysis of cryptographic algorithms; analysis of internationally standardized cryptographic algorithms;
  • Efficient implementation of cryptanalytic techniques;
  • Security evaluation of Russian cryptographic algorithms;
  • Efficient implementation of Russian cryptographic algorithms.

Invited speakers:

  • Xiaoyun Wang (China)
  • Markku-Juhani Olavi Saarinen (UK)

Special topic of this year: – “The future of asymmetric cryptography”:  Whether the recent theoretical results in elliptic curve discrete logarithm problem can affect elliptic curve cryptography in practice? 

CTCrypt 2016 gives the unique opportunity to get answer on this question first hand, because authors of these newest results have confirmed their participation in the discussion:

  • Claus Diem (Germany)
  • Igor Semaev (Norway)
  • Christoph Petit (UK) – online participation
  • Steven Galbraith (New Zealand) – online participation

The Workshop program also includes discussions practical aspects of ensuring information security with the use cryptographic facilities (will be held in Russian):

  1. Discussion of the project of open Requirements for encryption (cryptographic) facilities. For the first time such document will be discussed in an open session with participation of the regulatory authority representative.
  2. Cryptography in the internet of things.
