Danny Harnik: Security and Deduplication in the Cloud

Security and Deduplication in the Cloud

Danny Harnik, IBM Research

The talk will discuss security and privacy issues that arise from
deduplication in the cloud. Deduplication, is a popular form of compression
for large storage systems in which duplicate copies of files are replaced
by links to a single copy. This technique is also used to reduce the
bandwidth of incoming data to a storage cloud and has a significant effect
on the cost of maintaining such clouds (especially when deployed across
different users).

Sigurd Torkel Meldgaard : Title: Perfectly Secure Oblivious RAM without Random Oracles

We present an algorithm for implementing a secure oblivious
RAM where the access pattern is perfectly hidden in the information
theoretic sense, without assuming that the CPU has access to a random
oracle. In addition we prove a lower bound on the amount of
randomness needed for implementing an information theoretically secure
oblivious RAM.
Joint work with Ivan Damgård and Jesper Buus Nielsen
