Signcryption Technology Tightens Cyber Security
After nearly a three-year process, a revolutionary new technology known as signcryption has been formally recognized as an international standard by the International Organization of Standardization (ISO). Invented by College of Computing and Informatics’ professor Yuliang Zheng, signcryption is a data security technology by which confidentiality is protected and authenticity is achieved seamlessly at the same time.
When logging into an online bank account, signcryption prevents a person’s username and password from being seen by unauthorized individuals and, at the same time, confirms that person’s identity for the bank. More traditional means of cyber security make this a more time-consuming, two-step process.
News of the adoption by the ISO of signcryption as an international standard comes amidst daily reports of cyber attack and cyber crime around the world. Zheng adds that the application also will enhance the security and privacy of cloud computing.
“The adoption of signryption as an international standard is significant in several ways,” said Zheng. “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 is internationally recognized as an authority in cryptography and network security. He 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.”
