Edge cloud environments necessitate rapid, uninterrupted service continuity to meet the demanding needs of modern applications.
Building on an existing cloud platform, we integrate post-quantum cryptographic techniques to safeguard against "store now, decrypt later" threats, while ensuring smooth service continuity through efficient TLS session resumption.
Our solution leverages a hybrid key exchange mechanism that combines traditional Elliptic-Curve Diffie–Hellman with a post-quantum algorithm recently standardized by NIST to secure session establishment.
By enabling TLS session resumption, the system reduces the overhead of repeated full handshakes and minimizes latency during client mobility. Experimental evaluations demonstrate that our approach achieves robust security enhancements with minimal performance impact, making it a viable strategy for future-proofing edge computing infrastructures.
