Juan Tena Ayuso earned a Ph.D. in number theory from the University of Grenoble (1973) and in mathematics from the University Complutense of Madrid (1973). During the period 1973-82 he was a professor at the universities of Valladolid, Complutense of Madrid and Santander, and since 1983 he is a professor of algebra at the University of Valladolid.
His areas of research include cryptography, number theory and error correcting codes and he currently focuses on the study of elliptic curves arithmetic and geometry and their cryptographic applications. He has published numerous books about these issues and scientific articles and taught courses, conferences and seminars. He has advised six doctoral theses in the field of cryptography and correcting codes and has been the principal investigator and researcher of research projects funded by different Spanish ministries (education, education and science, science and technology, science and innovation, economy and competitiveness), Junta de Castilla y León, European Union and Spanish-French integrated actions. He has been the organizer and a scientific committee member of various conferences related to these subjects as well as referee, reviewer and evaluator of scientific papers and research projects.
Dr. Moti Yung. Google Inc.
Moti Yung is a cryptographer and computer scientist with Google Inc. He earned his Ph.D. from Columbia University in 1988, and worked in the past at the IBM Thomas J. Watson Research Center, been vice president and chief scientist at CertCo and been director of Advanced Authentication Research at RSA Laboratories. He has also held adjunct and visiting faculty appointments at Columbia, through which he has advised several Ph.D. students. In a 1996 publication with Adam Young, Yung coined the term "cryptovirology" for the use of cryptography as an attack tool by computer viruses and other malware (which predicted ransomeware attacks). Young and Yung are the authors of the book Malicious Cryptography: Exposing Cryptovirology (John Wiley & Sons, 2004). They also introduced the notion of "Kleptography" to describe the employment of cryptographic systems inside other cryptographic systems as attack tools by designers and manufacturers where the embedded malicious cryptologic has strong security properties against reverse-engineers, (also such attacks were predicated and have allegedly been employed).
Dr. Yung has contributed extensively to the foundations of basic cryptographic systems and protocols (such as to the notion of chosen-ciphertext security which is currently a major requirement from public-key encryption schemes operating on the Internet), to many areas of research in cryptography and data security, as well as to constructions leading to practical use and implementations in systems and networks. He was the annual "Distinguished Lecturer in Cryptography" of the International Association for Cryptologic Research (IACR) at Eurocrypt 2010. In 2013 he became a fellow of the Association for Computing Machinery (ACM), and in 2014 he became a fellow of the IACR.
