Gursimar Singh, Kiranpreet Kaur, Hrishikesh Hazarika, Manjot Singh, Abhinav Vashist · 2025
Conventional cryptographic approaches face increasing insecurity because quantum computing and attacks enabled by AI operate at a rapid speed of technological advancement. The review analyzes IEEE research activities on progressive cryptographic methods consisting of post-quantum cryptography (PQC) and fully homomorphic encryption (FHE) in addition to zero-knowledge proofs (ZKP) and AI-augmented cryptographic models. We explore both advantages and limitations in addition to applicable uses for protecting modern digital frameworks which include blockchain, IoT and 5G networks. Standardization efforts as well as hybrid crypto framework trends receive analysis in the article to establish long-lasting secure systems.
