One intensive week of theory, practice and discussions: 4-hour lectures and tutorials by international experts extended with practical workshops, labs and seminars, simulations, round-table discussions and working groups on hot topics

Topics of the year – the specific focus areas for 2015 edition will be:

  • Crypto for cloud – Searchable encryption and Homomorphic encryption (with practical simulations and demo-kit)
  • Crypto and security for smart devices – Internet of Things, the emerging standard of “industrial Internet”, theory and practice (semi-autonomous, robots) – specific aspect: Side channel attacks
    Dimitar Jetchev's lecture on searchable encryption, tele-presented by VGo

    Dimitar Jetchev tele-presented by VGo


  • elliptic curve cryptography (ECC), symmetric key, lattice-based cryptography
  • efficient arithmetic and integer factorization
  • functional encryption – identity-based encryption (IBE) and attribute-based encryption (ABE)
  • curve-based cryptography – theoretical and practical aspects
  • pairing-based cryptography
  • blind signatures and e-voting schemes
  • secure communications


  • personal secure devices, mobile security
  • secure architectures, “security by design” aspects
  • biometrics for security, multi-factor security (incl. “intuitive” methods)
  • e-Voting – practical realization
  • security in the cloud – searchable encryption lab
  • side-channel resistance – practical labs and simulation


  • Challenge CryptoBG*2015 participants >>> Define a problem, put it on the table on day 1 and get a short and simple solution by the end of the summer school!

Lectures and Tutorials – final program:
