CNXSoft: This is a guest post by Avishay Shraga, Sr. Director (CTO), Head of Security Technologies at Sony Semiconductor Israel, discussing IoT security as quantum computing draws near. The key to modern asymmetric cryptography is to create an equation that is easy to solve in one direction but difficult to reverse by an adversary in the other direction. Traditionally, this was done through modular arithmetic, where a large prime modulus and a generator were used to generate a key, although there are multiple methods to do so. The strength of this one-way function is measured by the time and computing power needed to reverse it. ECC 256, considered by many to be one of the gold standards in modern cryptography, would take millions of years to crack using current computing and capabilities. Today’s encryption standards are more than adequate in securing real-time and historical data in IoT devices. However, as […]
