Accelerating Encrypted Deduplication via SGX

Explore a conference talk on accelerating encrypted deduplication using Intel SGX technology. Delve into the innovative approach of SGXDedup, which leverages Intel SGX to enhance the performance of encrypted deduplication based on server-aided message-locked encryption (MLE). Learn about the secure interfaces implemented for MLE key generation and proof-of-ownership operations within SGX enclaves, as well as the various designs proposed to support secure and efficient enclave operations. Discover the significant speedups achieved by SGXDedup and its ability to maintain high bandwidth and storage savings, as demonstrated through evaluations on both synthetic and real-world workloads. Gain insights into outsourced storage, encrypted deduplication, MLE-based implementation, SGX basics, design goals, enclave management, renewable blinded key management, and SGX-based speculative encryption.
