Investigating the Impact of Quantum Computing on Existing Encryption Methods

The development of quantum computing technologies represents a critical risk for virtually all classical encryption systems (RSA, AES, ECC) and cybersecurity will sustain immense damage. RSA and AES in total depend on modern cyber security as they use factoring and discrete logarithm problems whose solving is perilous via quantum algorithms like Shor’s and Grover’s. This study analyzes the impact of quantum computing on current encryption systems and the need for post-quantum cryptography (PQC). More precisely, its postgraduate level reads laced based cryptography and other quantum resistant algorithms as potential solutions. The paper also discusses other obstacles transitioning from classical encryption to PQC such as performance overhead, infrastructure deviation, and global standardization policies. Precedence finds and computational simulations expostulate the necessity for quantum safe encryptions and accentuated suggestions for further developments. These findings express the need for protection when quantum computing era becomes ubiquitous.
