Abstract:

Cloud computing enables end-users with limited computational resources to
outsource large-scale computational problems to the public cloud, where
massive computational power can be easily utilized in a pay-per-use
manner. However, security is the major concern that prevents the wide
adoption of computation outsourcing, especially when end-user's
confidential data are processed and produced during the computation.
Therefore, enabling secure computation outsourcing mechanisms in the
public cloud becomes imperative while being challenging. In this talk, I
will present our recent research efforts on secure outsourcing of the
widely applicable linear programming computations. Our contribution is
three-fold. Firstly, the proposed mechanism protects the end-user's
sensitive input and output information from the cloud, while enabling
computation outsourcing. Secondly, the proposed mechanism provides
integrity guarantee over computation results such that any intentional or
unintentional result corruption at the cloud side can be effectively
detected. Thirdly, the proposed mechanism provides significant
computational savings at the end-user side, while imposing only marginal
security-related overhead on the cloud side. In this talk, I will also
discuss some other on-going research related to data service outsourcing
security in cloud, including secure search over encrypted cloud data and
secure and dependable storage service outsourcing.
