Abstract
The disclosure generally relates to methods and systems for estimating risk of enterprise application for quantum cryptography migration. Conventional software risk assessment tools that assess the quantum computer related security attacks are limited. The present disclosure solves the technical problems in the art for estimating risk of enterprise application for quantum cryptography migration. The methods and systems of the present disclosure formulated the problem based on a survival function in the probability theory, where possible chances of the enterprise application crypto surviving the quantum computer are calculated, and an estimated risk value is assigned to the enterprise software application. The methods and systems of the present disclosure discloses a risk estimator which take enterprise application specific metadata as the inputs and produces the risk score associated to the enterprise application against the quantum threats using a modified cox model and a modified rule of Mosca.
