Abstract
The introduction of 6G networks and the ongoing advancement in wireless and mobile technologies pose several security issues which need to be addressed for privacy-sensitive information or conversations. The assurance of Data confidentiality, integrity and authenticity is majorly based on Public Key Cryptography (PKC) especially in case when Digital signatures, key distribution and secure communication channel are required. The PKC security, however, is limited due to the dynamism of wireless and mobile contexts as well as constrained device resources that are facing constantly changing attack vectors. This study examines the existing practices (for asymmetric key management, distribution and creation) in these scenarios to find out potential vulnerabilities that are exploitable by attackers. To address these difficulties, the review proposes an original crossover cryptosystem that joins different cryptographic methods, including lattice-based encryption, quantum-resistant algorithms, and Elliptic Curve Cryptography (ECC), to upgrade protection from different dangers. The discoveries and commitments of this examination have critical ramifications for the improvement of secure and solid cryptographic conventions in 6G organizations, defending confidential data and correspondences in remote and versatile conditions.
