摘　　要：Cloud environments are essential for modern computing,but are increasingly vulnerable to Side⁃Channel Attacks(SCAs),which exploit indirect information to compromise sensitive data.To address this critical challenge,we propose SecureCons Framework(SCF),a novel consensus⁃based cryptographic framework designed to enhance resilience against SCAs in cloud environments.SCF integrates a dual⁃layer approach combining lightweight cryptographic algorithms with a blockchain⁃inspired consensus mechanism to secure data exchanges and thwart potential side⁃channel exploits.The framework includes adaptive anomaly detection models,cryptographic obfuscation techniques,and real⁃time monitoring to identify and mitigate vulnerabilities proactively.Experimental evaluations demonstrate the frameworks robustness,achieving over 95%resilience against advanced SCAs with minimal computational overhead.SCF provides a scalable,secure,and efficient solution,setting a new benchmark for side⁃channel attack mitigation in cloud ecosystems.
