Quantum-Resistant Encryption Protocols

Abstract

The paper compares lattice-based, hash-based, and hybrid key exchange strategies for enterprise-grade cloud security migration plans.

Key Highlights

• Hybrid key exchange improved resilience without adding unacceptable handshake overhead
• Migration playbooks can phase in quantum-safe encryption alongside existing TLS stacks
• Operational guidance is tailored for regulated enterprise deployments

Methodology

1. 1Reviewed current cryptographic standards and candidate post-quantum algorithms
2. 2Prototyped secure handshakes in simulated enterprise network topologies
3. 3Measured latency, CPU overhead, and rollout complexity under mixed workloads

Findings

• Hybrid schemes are the best near-term transition path for large enterprises
• Certificate rotation policy is the largest operational bottleneck
• Incremental adoption reduces risk while preserving interoperability
