Many scientific workflows are data intensive where a large volume of intermediate datasets is generated during their execution. Some valuable intermediate datasets need to be stored for sharing or reuse. Traditionally, they are selectively stored according to the system storage capacity, determined manually. As doing science on cloud has become popular nowadays, more intermediate datasets in sc...

Entangled cloud storage (Aspnes et al., ESORICS 2004) enables a set of clients to “entangle” their files into a single clew to be stored by a (potentially malicious) cloud provider. The entanglement makes it impossible to modify or delete significant part of the clew without affecting all files encoded in the clew. A clew keeps the files in it private but still lets each client recover his own ...

In this extended abstract, we explain a demo of the leakage-resilient authentication and data (key) management system which can be regarded as a prominent solution for secure cloud storage.

The convention of cloud computing has increased promptly in the society. Cloud computing have many benefits in terms of accessibility of data and low expenditure. A fundamental characteristic of the cloud services is that user’s data are usually processed remotely in unknown machines that users do not operate. It can be transformed into a momentous roadblock to the wide adoption of cloud servic...

Advanced Persistent Threat (APT) attackers apply multiple sophisticated methods to continuously and stealthily steal information from the targeted cloud storage systems and can even induce the storage system to apply a specific defense strategy and attack it accordingly. In this paper, the interactions between an APT attacker and a defender allocating their Central Processing Units (CPUs) over ...

In our everyday lives, we create massive amounts of data. But how much does it really cost to store data? With ever decreasing cost of storage media, a popular misconception is that the cost of storage has become cheaper than ever. However, we argue that the cost of storing data is not equal to the cost of storage media alone – rather, many often ignored factors including human, infrastructure,...

Cloud storage provides a highly available, easily accessible and inexpensive remote data repository to clients who cannot afford to maintain their own storage infrastructure. While many applications of cloud storage require security guarantees against the cloud provider (e.g., storage of high-impact business data or medical records), most services cannot guarantee that the provider will not see...

Cloud makes data storage very smart. It provides enormous amount of space to store the user’s data. These data are instantly available for the users at any time and it reduces the cost with respect to hardware support, technical experts available and license of the database. It leverages the small and medium scale enterprise straight away to start their business. Nevertheless cloud has many adv...

Cloud computing has evolved from a risky and confusing concept to a strategy that organization large and small are beginning to adopt as part of their to overall computing strategy. Cloud computing is a method of providing a set of shared computing resources that includes application, computing, storage, netorking, development and deployment platforms as well as business processes.. Research on...
