TLDR
This paper presents a new verifiable search scheme for outsourced database supporting data update operation without any pre-computation, and shows that this work cannot be effectively adoptable in dynamic database scenario.Abstract:
The notion of database outsourcing enables the data owner to delegate the database management to a cloud service provider (CSP) that provides various services to users of the database. It is inevitably to bring in new security challenges such as data privacy and query integrity. Although the issue of data privacy can be solved by database encryption techniques, query integrity is still an important challenge in database outsourcing scenario. Recently, some researchers present a verifiable auditing scheme, which can simultaneously achieve the correctness and completeness of search results even if the CSP intentionally returns an empty set. However, it requires the data owner to count the number of each identical item before outsourcing the database, which seems that this work cannot be effectively adoptable in dynamic database scenario. In this paper, we present a new verifiable search scheme for outsourced database supporting data update operation without any pre-computation.read more

Secure outsourcing of scientific computations
TL;DR: No single disguise technique is suitable for a broad range of scientific computations but there is an array of disguise techniques available so that almost any scientific computation could be disguised at a reasonable cost and with very high levels of security.
