Researchers are attempting to develop new forms of cryptography that could not be cracked by powerful quantum computing devices that are in the works.

That requires devising public key cryptosystems based on computational problems that are difficult to break even using quantum algorithms, says Divesh Aggarwal, principal investigator at Singapore's Center for Quantum Technologies.

"The essential idea is you have to come out with a computational problem that you can base public key cryptosystems on and for which we don't know how to solve these problems using quantum algorithms," Aggarwal says in an interview with Information Security Media Group.

The National Institute of Standards and Technology in the U.S. is working on standardized quantum proof cryptographic keys, he notes.
