Global Vision

Trusted and Resilient Cryptography

Crypto Leadership Team

The Infosec Global security leadership team has deep professional and academic expertise across the full spectrum of security and cryptography. Our experts are the original inventors of key cryptographic technologies, and designers of security protocols and standards. With extensive ‘real-life’ experience, all have held senior executive positions with both large corporations and fast-growing start-ups.

Dr. Taher Elgamal

Father of SSL, co-founder

The International nature of Infosec Global's business is most unique. Offerings around the various international cryptographic solutions are very important to our customers and provide a competitive edge over their peers. Infosec Global has the most powerful skills in the world in cryptography and will continue to be the leader in this space.
Dr. Elgamal has invented several standards in data security and digital signatures, including the design of the ElGamal discrete log cryptosystem and ElGamal signature scheme. The latter became the foundation for Digital Signature Algorithm, which was adopted as the Digital Signature Standard for the Federal Information Processing Standard by the National Institute of Standards and Technology in the United States. FIPS is a requirement for use in all computers of non-military government agencies. Dr. Elgamal also developed the Secure Socket Layer (SSL) protocol used in Internet security, including writing the patents and developing the original products using SSL. He is responsible for promoting SSL as the Internet security standard at the Internet Engineering Task Force. Within the commercial sector, he developed the RSA Bsafe cryptography products such as the first version of the VeriSign CA product. He participated in the Secure Electronic Transaction (SET) credit card payment protocol, and a number of Internet payment schemes, with efforts led by VISA and MasterCard. Dr. Elgamal has held many executive and board seats with security related companies, including Diversinet, Tumbleweed, First Information Security and Securify (now part of McAfee). He holds a Doctorate degree in Electrical Engineering from Stanford University and was recognised with a Lifetime Achievement Award from RSA in 2009.

Prof. Dr. Ueli Maurer

Head of the information security and cryptography research group Swiss Federal Institute of Technology (ETH), Zurich

Information security is a key issue for businesses and governments, positioned on the CEO's agenda. Information security makes headlines because of increasing system vulnerabilities, values at risk, and number of attacks. But security is not only about preventing attacks, security technologies are key enabling technologies for the future of IT.
Cryptography is the primary such enabling technology for new and emerging security-critical applications, including secure communication, digital signatures, digital money, e-voting, auctioning systems, etc. Cryptography is based on clear and deep mathematical principles, and the security of cryptographic protocols is usually proven rigorously by a mathematical proof. Ueli Maurer is professor of computer science and head of the Information Security and Cryptography Research Group at the Swiss Federal Institute of Technology (ETH), Zurich. His research interests include theory and applications of cryptography, information security, theoretical computer science, information theory, and discrete mathematics. One of his long-term research goals is to establish a constructive theory of cryptography and to apply it to the modular design of provably secure cryptographic protocols. He has served as editor-in-chief of the Journal of Cryptology from 2002 to 2010, as associate editor for the IEEE Transactions on Information Theory, and currently serves as associate editor for the Journal of Computer and System Sciences. He is an IEEE Fellow, an ACM Fellow, an IACR Fellow, and a member of the German Academy of Sciences (Leopoldina). He was the 2000 Rademacher Lecturer of the Department of Mathematics at the University of Pennsylvania, received the 2013 Vodafone Innovation Award for Mobile Communications and the 2016 RSA Award for Excellence in the Field of Mathematics. Maurer has served many companies and start-ups as board member and consultant.

Prof. Dr. Vincent Rijmen

Co-Designer of Advanced Encryption Standard (AES), Prof. KU Leuven (Mathematical theories for the design of symmetric cryptography primitives)

Strong cryptography is still the basis for trustworthy security.
Vincent Rijmen completed his PhD in cryptography at the University of Leuven (KU Leuven), Belgium in 1997. He is co-designer of the algorithm Rijndael, which has become the Advanced Encryption Standard (AES) in 2001, and has been included in many other standards since. Rijmen is also the co-designer of the WHIRLPOOL cryptographic hash function, which is included in ISO/IEC 10118-3. Rijmen manages the team working on symmetric-key cryptography at COSIC (since 2008). He was the leader of Symlab, the virtual lab on symmetric techniques of the European Network of Excellence ECRYPT II. He led the research team working on cryptanalysis at IAIK, Graz University of Technology (2004-2008), and was Chief Cryptographer with Cryptomathic NV (2001-2004). Rijmen is currently editor of the following journals: Journal of Cryptology (since 2013), Information Processing Letters (since 2012); Designs, Codes & Cryptography (since 2007), Journal of Universal Computer Science (since 2004). Rijmen teaches the courses “Cryptography & Network Security” and “e-Security” in the Master of Science in Electrical Engineering at KU Leuven.

Prof. Dr. Alfred Menezes

Co-Founder of the centre for applied cryptography research at Waterloo University and Co-Author of the "Handbook of Applied Cryptography"

While the core tools in cryptography are quite well understood, implementing these tools securely and efficiently in large-scale applications is extremely challenging. This is especially so for organisations with long-term security needs.
Alfred Menezes is Professor and Chair in the Department of Combinatorics & Optimisation, Faculty of Mathematics, at the University of Waterloo. His research interests are in elliptic curve cryptography, practice-oriented provable security, and algorithmic number theory. Alfred received his PhD in 1992 from the University of Waterloo. He is co-author of the widely used Handbook of Applied Cryptography and Guide to Elliptic Curve Cryptography. His work has included mathematical, engineering, and computer science aspects of public-key cryptography. He has discovered and analysed attacks on the elliptic curve discrete logarithm problem. He has developed and analysed protocols for key establishment, some of which have been standardised by the American National Standards Institute (ANSI) and the US government's National Institute of Standards and Technology (NIST). With Neal Koblitz, he has an ongoing project whose objective is to understand the practical implications of security proofs. Alfred was a co-founder of the Centre for Applied Cryptographic Research (CACR) at the University of Waterloo, and served as its Managing Director from 2005 to 2011. He has co-organised numerous workshops on elliptic curve cryptography, security, and privacy. In 2012, he was a recipient of the University of Waterloo's Distinguished Teaching Award.

Prof. Dr. Arjen Lenstra
