With the development of IoT (Internet of Things) technology, the application area has been diversified and the number of users using this service also has increased greatly. Real time big data generated by many IoT devices is no longer suitable for processing in a cloud computing environment. To solve this issue, fog computing is suggested which minimizes response time and makes real time processing suitable. However, security requirement for new paradigm called fog computing is not established until now. In this paper, we define models for fog computing, and the security requirements for the defined model.

“…Despite the effort invested in improving the existing de-duplication algorithm to provide users with adequate privacy, thus far there is no work that has a solution for an effective and secure combination of the two [18]. Current systems rely primarily upon three main data de-duplication strategies [20], [17] as follows: Firstly, Whole File strategy typically utilises a file's cryptographic hash value as an identifier. If two or more files hash are of the same value, they are assumed to have identical content and only stored once.…”

“…According to [17], the location at which data de-duplication is performed is also very important; if the data are deduplicated at the client side, then it is known as the source-based de-duplication or otherwise, target-based deduplication. In source-based de-duplication, the client will perform hash functions on each data segment that needs to be uploaded.…”

Abstract-The cloud storage services bring forth infinite storage capacity and flexible access capability to store and share large-scale content. The convenience brought forth has attracted both individual and enterprise users to outsource data service to a cloud provider. As the survey shows 56% of the usages of cloud storage applications are for data back up and up to 68% of data backup are user assets. Enterprise tenants would need to protect their data privacy before uploading them to the cloud and expect a reasonable performance while they try to reduce the operation cost in terms of cloud storage, capacity and I/Os matter as well as systems' performance, bandwidth and data protection. Thus, enterprise tenants demand secure and economic data storage yet flexible access on their cloud data.In this paper, we propose a secure de-duplication solution for enterprise tenants to leverage the benefits of cloud storage while reducing operation cost and protecting privacy. First, the solution uses a proxy to do flexible group access control which supports secure de-duplication within a group; Second, the solution supports scalable clustering of proxies to support large-scale data access; Third, the solution can be integrated with cloud storage seamlessly. We implemented and tested our solution by integrating it with Dropbox. Secure de-duplication in a group is performed at low data transfer latency and small storage overhead as compared to de-duplication on plaintext.

“…Pasqualepuzioet. al [5] proposedClouDedup, a secure and efficient storage service that assured block-level deduplication and data confidentiality at an equivalent time. Even whenbased on convergent encryption, ClouDedup remained secure because of a component that implemented an additional encryption operation and an access control mechanism.…”

Cloud storage is one of the services provide in cloud computing which has been increasing in reputation. With the growing data size of cloud computing, a decrease in data volumes could help provider reducing the costs of running large storage system and saving energy use. So data de-duplication techniques have been brought to recover storage competence in cloud storages. In this paper, we suggest a dynamic de-duplication system for cloud storage, which aim to advance storage competence and maintain redundancy for fault acceptance.
