Talk Title: Encrypted Non-volatile Main Memory Systems
Abstract: Non-volatile memory (NVM) technologies are considered as promising candidates of the next-generation main memory. However, the non-volatility of NVMs leads to new security vulnerabilities. Memory encryption can be employed to mitigate the security vulnerabilities, but it increases the number of bits written to NVMs due to the diffusion property and thereby aggravates the NVM wear-out induced by writes. To address these security and endurance challenges, we propose DeWrite, a secure and deduplication-aware scheme to enhance the performance and endurance of encrypted NVMs based on a new in-line deduplication technique and the synergistic integrations of deduplication and memory encryption. Specifically, it performs low-latency in-line deduplication to exploit the abundant cache-line-level duplications leveraging the intrinsic read/write asymmetry of NVMs and light-weight hashing. It also opportunistically parallelizes the operations of deduplication and encryption and allows them to co-locate the metadata for high efficiency. DeWrite was implemented on the gem5 with NVMain.

CCI presents Blockfinity's "Bringing Cities on to the Blockchain - Los Angeles"
Thu, Oct 04, 2018 @ 07:00 PM - 09:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Receptions & Special Events
Blockchain is a fast-growing technology with the intent to decentralize bureaucratic processes, create transparent transactions between multiple parties, and optimize enormous databases. The applications are endless when it comes to government, and municipalities, but our goal is to bring the community together to discuss theory, implementation, and case studies of how cities may work with Blockchain.
Let's imagine the changes in social, economic and environmental by ridding of bureaucracy in city infrastructure such as piles of papers, giant traffic jams, documentation errors and double transactions. Join our discussion to understand which cities around the world are implementing blockchain and how, what can be improved, and how would this help us here in Los Angeles.
