Advent of quantum computing can lead to big security challenges, and Sebi is engaged in preparing the system to be safe ahead of its adoption, the capital market regulator’s chairman Tuhin Kanta Pandey said on Wednesday.

Pandey said quantum computing has the technological capabilities to make it possible for bad actors to compromise passwords, which were long presumed to be very secure and hence, it is necessary to prepare the system on this front. Sebi has prepared an “action plan” to ensure quantum readiness of all the stakeholders that it regulates, Pandey said at the annual GFF here.

There is a lot of research which is going into quantum computing, which will rely on principles of quantum mechanics to solve complex problems far beyond the capabilities of classical computers, Pandey said. The career bureaucrat-turned-regulator said there is a possibility of quantum computing coming and once it comes, the normal cryptography used to set passwords may be the first ones to break.

“We have quantum safe computing (priority) keeping 2028 or 2029 as the date (when quantum comes) on how do we prepare ourselves as an industry to go for quantum-safe cryptography based on an action plan where we discover, we prepare and then we act within the next two-three-four years,” Pandey said.

Meanwhile, answering a query on technology neutrality, Pandey said he does not see the ability to continue holding shares in a paper form continue for long in a system which has transitioned to dematerialization long back. On the concept of technological neutrality, a hotly contested issue, he chose to go public with his skepticism with a nuanced take.
