Secure cloud storage with data dynamic using secure network coding technique
The document presents the design of secure cloud storage protocols for dynamic and append-only data, leveraging secure network coding techniques. It introduces two protocols, DSCS I for dynamic data and DSCS II for append-only data, detailing their construction, performance evaluation, and security definitions. Additionally, the document outlines the challenges and considerations in developing efficient and secure cloud storage solutions from secure network coding protocols.

We explore the possibility of providing a generic construction of a DSCS protocol from any SNC protocol. We discuss the challenges for a generic construction in details and identify some SNC protocols suitable for constructing efficient DSCS protocols. We construct a publicly verifiable DSCS protocol (DSCS I) from an SNC protocol . DSCS I handles dynamic data, i.e., a client can efficiently perform updates (insertion, deletion and modification) on the outsourced data. We discuss the (asymptotic) performance and certain limitations of DSCS I. We provide the formal security definition of a DSCS protocol and prove the security of DSCS I. As append-only data are a special case of generic dynamic data, we can use DSCS I (which is based on ) for append-only data. However, we identify some SNC protocols that are not suitable for building a secure cloud storage for generic dynamic data, but efficient secure cloud storage protocols for appendonly data can be constructed from them. We construct such a publicly verifiable secure cloud storage protocol (DSCS II) for append-only data by using an SNC protocol proposed by Boneh et al.. We discuss the (asymptotic) performance of DSCS II which overcomes some limitations of DSCS I. We implement DSCS I and DSCS II and evaluate their performance based on storage overhead, computational cost and communication cost. System Architecture:
