  1. Research and teaching activities in the CrySyS Lab Levente Buttyán Laboratory of Cryptography and System Security (CrySyS) Budapest University of Technology and Economics Department of Telecommunications www.crysys.hu

  2. Current members faculty: Boldizsár Bencsáth, PhD, AssistantProfessor Levente Buttyán, PhD, Associate Professor (head of the lab) Márk Félegyházi, PhD, Assistant Professor István Vajda, DSc, Professor post doc researcher: Amit Dvir, PhD (from Israel) PhD candidates and PhD students: Tamás Holczer (privacy in RFID systems, vehicular networks, sensor networks) Gergely Kótyuk (privacy in social networks, applications of machine learning) Áron Lászka (robustness of network toplogies) Gábor Pék (security of virtualized systems, code attestation, verification of code execution) Ta Vinh Thong (formal verification of security protocols) + ~10 students working on diploma and semester projects

  3. Mission internationally recognized, high quality research on security and privacy in computer networks and systems problem driven, project oriented research  we are committed to establish and participate in R&D projects, in which we collaborate with industrial and other academic partners teaching network and system security, privacy, and cryptography in the context of university courses, laboratory exercises, and semester projects provision of consulting services without compromising the general academic objectives

  4. Research main research domains economics of security and privacy (incentive design, quantitative risk management, cyber insurance) security of cloud computing (vulnerability analysis of virtual machines, malware analysis techniques) security and privacy in wireless networked embedded systems (sensor networks, body area networks, vehicular communications, RFID systems) funding international projects funded by the European Commission Ericsson through the HSN Lab national funding agencies (OTKA, NKTH)
