Johann van der Merwe Director & Security Architect at Telic Consulting Johann has over 13 years of dedicated security experience spanning R&D, leading consulting teams, playing the role of a group CISO, leading security businesses and security architecture teams. He can engage on security at a business executive (board) level and also perform detailed security technical designs on complex systems. Johann was intimately involved with the drafting of ISO27001 and ISO27002 representing South Africa at ISO SC27 WG1 over a 4 year period. This year (2017) he lectured a module at the Rhodes MSc in Information Security. He has spoken at ITWeb Security Summit and a few other conferences over the years. His PhD focused on trust establishment and key management for securing distributed systems. The same mechanisms underpin block-chain and many other security controls in the enterprise. Specialities: Leading a security practice, leading security strategy development, leading security transformations, security function/organisation/capability establishment, security programme/project management, security project rescue/turnaround, enterprise security architecture, solution architecture and design, security engineering, complex technology implementations, deep technical security assessments & security analytics / threat detection. Industries: Financial Services, Telecommunications, Mining, Energy, Retail, Aviation, Public Services, Revenue, R&D, Defense, Manufacturing, Physical Security Services, Technology Services, Media & Entertainment.

Johann van der Merwe obtained his MSc and PhD degrees in Electronic Engineering within the communications research group at the University of KwaZulu-Natal. Johann performed information security and communication technology research and development under contract with ARMSCOR, the Armaments Corporation of South Africa. The research and development focused on the security of mobile ad hoc networks (MANETs) and distributed communication systems. Within the information and communication technology security field Johann considered the following areas:

• Peer-to-peer key management (public key management).
• Group key management.
• Group communications.
• Key management in vehicular ad hoc networks.
• Threshold cryptography (in MANETs and fully distributed systems in general).
• Secret sharing schemes (distributed systems).
• Secret update schemes (distributed systems).
• Secret share redistribution schemes (distributed systems).
• Multi party digital signatures (threshold multi-signature schemes).
• Security proofs within the standard model, random oracle model and generic model.
• Self-certified public key schemes.
• Mobile IPv6 security.
• Crypto-based identifiers.
• Fully self-organized security systems.
• Efficient data dissemination in mobile wireless networks.
• Elliptic curve cryptography.
• Secure routing protocols for mobile networks.
• Key Management in Peer-to-Peer Networks.  
  

During his research Johann has captured some academic security references into a database. These are in general good publications mostly in the security fields listed above. The bibtex file containing most of  the references can be downloaded here.
