Dr. Taher Elgamal
Recipient of TechWadi’s 2007 “Achievement in Startups” Award

Chief Technology Officer, Tumbleweed Communications.
Dr. Taher Elgamal is an Egyptian American cryptographer. In 1985, Elgamal published a paper titled “A Public key Cryptosystem and A Signature Scheme based on discrete Logarithms” in which he proposed the design of the “ElGamal discrete log cryptosystem and of the ElGamal signature scheme”. The latter scheme became the basis for Digital Signature Algorithm (DSA) adopted by National Institute of Standards and Technology (NIST) as the Digital Signature Standard (DSS). He also participated in the ‘SET’ credit card payment protocol, plus a number of Internet payment schemes.
Dr. Elgamal obtained his Bachelor of Science degree from Cairo University, and Masters and Doctorate degrees in Computer Science from Stanford University.
He served as chief scientist at Netscape Communications from 1995 to 1998 where he was a driving force behind SSL. He also was the director of engineering at RSA Security Inc. before founding Securify in 1998 and becoming their CEO. When Securify was acquired by Kroll-O’Gara he became the president of its information security group. Presently (2004), Securify is again independent and Elgamal is Chief Technical Officer & Co-Chair of the Board of Directors. In addition, Elgamal sits on the board of FaceTime Communications, a company which provides security solutions for instant messaging and peer-to-peer applications and Phoenix Technologies makers of BIOS systems. Most recently, Elgamal serves as Chairman and CEO of Ektasis, a Silicon Valley startup he founded in late 2004 with co-founders Phil Straw and Mark Chen.
In October 2006 he joined Tumbleweed Communications in a capacity of a Chief Technology Officer.
