Abstract: ABSTRACT METHOD AND SYSTEM TO ESTIMATE RISK FOR A SOFTWARE APPLICATION DUE TO QUANTUM THREAT Conventional risk estimation techniques perform dynamic analysis of application or use models which require training data. Present disclosure provides method and system to estimate risk for a software application due to quantum threat by static analysis. A set of records pertaining to the application is received and parsed to obtain application, crypto and platform parameters. In addition, list of quantum vulnerable algorithms, number of Qubits required to break a cryptographic algorithm used by the application and a current Qubit number are also received. Then, value of Quantum Day is determined based on the current Qubit number and the number of Qubits required to break the cryptographic algorithm used by the application. Further, SOD (Severity, Occurrence, Detection) scores are calculated for each parameter, and they are multiplied to determine Risk Priority Number (RPN) for each parameter. Finally, RPNs of all parameters are summed up to estimate overall risk of the application. [
