摘要：Cloud computing has important idea for the privacy of personal information as well as for the secrecy of business information. The location of information in the cloud may have important effects on the privacy and confidentiality protections of information. Especially for Sensitive Areas like Hospital Management System. We provide a design and implementation of self-protecting Client medical records (CMRs) using Ciphertext-Policy attribute-based encryption (CP-ABE). However, before cloud-based CMR systems can become a reality, issues of data security, patient privacy, and overall performance must be addressed. As standard encryption (including symmetric key and public-key)techniques for CMR encryption/decryption cause increased access control and performance overhead, the paper proposes the use of Ciphertext- Policy Attribute-Based Encryption (CP-ABE) to encrypt CMRs based on healthcare providers’ attributes or credentials; to decrypt CMRs, they must possess the set of at- tributes needed for proper access. This Method is not only is it inexpensive but it also provides the flexible, wide-area mobile access increasingly needed in the modern world.
