In the state of art technology, substantial amount of research on quantum computers is explored. Mathematical problems unsolved by classical computer are well addressed by quantum device. Such future computers are capable of breaking existing public key crypto systems very well. The strength of any cryptographic technique depends on key’s size and secure transmission. Need arises to build post quantum security algorithms to counter act the quantum attacks. This paper is intended to present generalized approach in building robust and more secure key generation unit for cryptography. Algorithms are proposed for generating private and public keys. Further paper discusses on design of proposed key generation algorithm using reversible logic to reduce the power dissipation. Paper also presents quantum resistant design approach for asymmetric public key algorithm. Functional verification and performance analysis in terms hardware requirement of reversible design is carried out and discussed.
