SURVEY ON DYNAMIC DATA SHARING IN PUBLIC CLOUD USING MULTI-AUTHORITY SYSTEM (140371)

Abstract : The continuous development of cloud computing,seve ral trends are opening up to new forms of outsourci ng. Public data integrity auditing is not secure and efficient for shared dynamic data. In existing scheme figure out the collusion attack and provide an efficient public integrity au diting scheme,with the help of secure group user r evocation based on vector commitment and verifierĖlocal revocation group signature. It provides secure and efficient s cheme which support public checking and efficient user revocati on. Problem of existing work they used TPA (Third p arty auditor) for key generation and key agreement. Use of TPA as central system if it fails then whole system gets failed. If we are working with cloud,user identity is major conc ern because user doesnít want to reveal his persona l information to public. This concept not included in it. In this paper,based these conís we proposed a dynamic dat a sharing in public cloud using multi-authority system. The prop osed scheme is able to protect userís privacy again st each single authority. .
