QUANTUM-RESISTANT CRYPTOGRAPHY: DEVELOPING ENCRYPTION ALGORITHMS TO SAFEGUARD DATA AGAINST FUTURE QUANTUM COMPUTING THREATS

Abstract

This study investigates the performance and security of quantum-resistant cryptographic algorithms, assessing their potential to protect data from quantum computing threats. The research evaluates various cryptographic techniques, including lattice-based, code-based, hash-based, and isogeny-based systems, comparing them in terms of encryption and decryption speeds, memory consumption, computational overhead, and resistance to quantum attacks.Lattice-based algorithms require increased amounts of memory and computational resources yet maintain low simulated attack success rates which makes them optimal for quantum resistance.  Research established hash-based cryptosystems operated faster but scientists proved them to be vulnerable to quantum attacks.  Scientific experts demonstrated hybrid cryptographic systems based on conventional and quantum-resistant algorithms as a viable security-speed compromise solution.  Lattice-based systems maintain the highest level of scalability for extensive systems according to scalability testing results yet multivariate poisson systems show inadequate scalability features.  Technical experts confirmed that quantum-resistant cryptographic systems function in reality but organizations require solutions to overcome operational and resource expenditure hurdles.  This research creates post-quantum cryptography systems that prove safe and effective through the presentation of algorithm optimization insights and their practical applications framework.  The study demonstrates why we need continued development and research to maintain data security because quantum computing will transform in the coming quantum era.
