Signcryption is the technology that protects confidentiality and authenticity, seamlessly and simultaneously.

One case in point is when you log in to your online bank account, signcryption prevents unauthorized individuals from seeing your username and password. At the same time, it confirms your identity for the bank.

After nearly a three-year process, University of North Carolina at Charlotte professor Yuliang Zheng’s research efforts have been formally recognized as an international standard by the International Organization of Standardization (ISO). Zheng invented the new technology and he continues his research in the College of Computing and Informatics.

News of the ISO adoption comes amidst daily reports of cyber attack and cyber crime around the world. Zheng said the application will also enhance the security and privacy of cloud computing.

“The adoption of signryption as an international standard is significant in several ways,” he said. “It will now be the standard worldwide for protecting confidentiality and authenticity during transmissions of digital information.”

Known as the father of the signcryption technology, Zheng has published more than 200 scholarly articles and books on security and holds several patents in cyber security. His most recent publication “Practical Signcryption” is currently on sale worldwide.

“This will also allow smaller devices, such as smartphones and PDAs, 3G and 4G mobile communications, as well as emerging technologies, such as radio frequency identifiers (RFID) and wireless sensor networks, to perform high-level security functions,” he said. “And, by performing these two functions simultaneously, we can save resources, be it an individual’s time or be it energy, as it will take less time to perform the task.”
