Secure Data transfer in Cloud Storage Systems using Dynamic Tokens
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 1
Abstract
Cloud computing is the delivery of computing as a service rather than a product. It provides shared resources, software, and information to computers and other devices over a network. The increasing network bandwidth and reliable yet flexible network connections make it even possible that users can now subscribe high quality services from data and software that reside solely on remote data centers. We can store and retrieve the data as we like using cloud computing. To maintain the data securely in distributed environment i.e., on clouds we propose an effective and flexible distributed scheme with Token Generation algorithm for data files checking as a secure and dependable cloud storage service. A new scheme was introduced to encrypt with the user specified key parameters to make the resource more robust. We derive a new algorithm which is very light weight and easy to compute. Here we stores the encrypted blocks into cloud and perform token checking on this encrypted blocks which gives more security to data. We verify the data effectively in case of any block modifications of files before storing to Clouds by token acknowledgment. The proposed scheme is highly efficient and resilient against attacks like Byzantine server failures, malicious data modification attack. Two way verification of file blocks which results more robust and ensure that data will not be modified before reaching to clouds.
