TPTVer: A Trusted Third Party Based Trusted Verifier for Multi-Layered Outsourced Big Data System in Cloud Environment
TPTVer: یک تایید کننده معتبر مبتنی بر شخص ثالث برای سیستم داده های بزرگ برون سپاری چند لایه در محیط ابری-2018 Cloud computing is very useful for
big data owner who doesn’t want to manage
IT infrastructure and big data technique details. However, it is hard for big data owner to
trust multi-layer outsourced big data system
in cloud environment and to verify which
outsourced service leads to the problem. Similarly, the cloud service provider cannot simply
trust the data computation applications. At last,
the verification data itself may also leak the
sensitive information from the cloud service
provider and data owner. We propose a new
three-level definition of the verification, threat
model, corresponding trusted policies based
on different roles for outsourced big data
system in cloud. We also provide two policy
enforcement methods for building trusted data
computation environment by measuring both
the MapReduce application and its behaviors
based on trusted computing and aspect-oriented programming. To prevent sensitive information leakage from verification process,
we provide a privacy-preserved verification
method. Finally, we implement the TPTVer, a
Trusted third Party based Trusted Verifier as a
proof of concept system. Our evaluation and
analysis show that TPTVer can provide trusted
verification for multi-layered outsourced big
data system in the cloud with low overhead.
