Proofs of Storage for Cloud and Blockchains

Series: Department Seminar

Speaker: Prof. Sushmita Ruj Faculty of Engineering Lead of UNSW Institute for Cybersecurity, IFCYBER, Associate Professor in the School of Computer Science and Engineering, UNSW, Sydney

Date/Time: Jan 08 11:00:00

Location: CSA Auditorium, (Room No. 104, Ground Floor)

Abstract:
Cloud service providers can act maliciously and tamper with the data. Proofs of storage were introduced to enable honest clients to verify data integrity.  In the first part of the talk, we will present the concept of proofs of storage and present some constructions.  In the second part, we will consider the setting where clients can be dishonest. In the third part, will then discuss decentralised storage and data structures to support blockchain enabled decentralised storage. We will end with many some questions.
