Abstract

Recently, Hota et al. present a Capability-based Cryptographic Data Access Control in Cloud Computing. This scheme implements data storage, user authorization, data access and integrity checking. However, we find two fatal attacks in the data exchange between CSP and User. These attacks makes a registered user can intercept another legal user’s file and decipher it. To avoid these attacks, we give an improvement to Hota et al’s scheme and can resist theses attacks. Meantime, to make Hota’s scheme be applicable, we propose a novel data access protocol in cloud computing. Our scheme guarantees data confidentiality and secure data access between User and CSP. Security analysis shows that the scheme can resist various attacks.
