Client Server Encryption

End-to-end encryption policies must take into account everything from input to output and storage. Encryption technology is divided into five categories: file-level or folder-level encryption, volume or partition encryption, media-level encryption, field-level encryption and communication content encryption. They can be defined further by the encryption key storage mechanism. Let's take a look at the grim forecast: According to the US Privacy information exchange, One-third of the U.S. people will encounter the loss or leakage of personally identifiable information from companies that store data electronically this year. Whether that number is not exactly right, anyway the public knows the data leaks ...

The necessity of database encryption large database management system platform is typically Windows NT and Unix, these operating system security level is usually C1, C2 level. They have user registration, user identification, Arbitrary access control (DAC), audit and other security functions. Although the DBMS on the basis of the OS added a number of security measures, such as access control based on permissions, but the OS and DBMS on the database file itself is still lack of effective protection measures, experienced online hackers will "bypass", directly using the OS tools to steal or tamper with the database files ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Windows 7 uses different forms of Windows encryption sharing with older versions, which can also create barriers to Windows sharing visits between different versions while improving network share security. Sometimes, although each other can be viewed to share files, but many times, users can only stay on the "discovery" level, ...

Encryption is one of the basic security tools for protecting data in a multi-tenant environment. For private cloud computing and public cloud computing, especially when you share a repository with different sensitive levels of data with other users. When you do not have full control over the cloud computing environment, it is invaluable that cloud computing encryption allows you to protect your data if implemented properly. But cloud computing encryption is not the same encryption technology used in a single tenant environment where you have full control. If implemented improperly, cryptographic techniques may not achieve the functions and effects you expect to achieve. Moreover, those in the traditional infrastructure ...

Data is generally protected by PKI, where data is encrypted, it creates a public key, theoretically decrypted by the private key held by the authorized person. However, this type of data protection extended to the cloud is complex. Migrating to the cloud poses a new set of complex security issues for the IT team due to the lack of direct control over data security. In addition, cloud vendors believe that data security is a common responsibility for service providers to ensure physical security, and that users must ensure their own servers and data. It is speculated that encryption and key management require a strategy, and that the key needs to be stored outside the cloud rather than inside ...

To be able to better enterprise data security, away from the growing number of experienced hacker attacks, HP's new capabilities help IT staff encrypt data from the points they create, regardless of whether the data is in the cloud or local. 　　HP Atalla Cloud Encryption protects a range of unstructured data, such as payment information, electronic health files, and core critical systems of financial institutions, and can run through their entire lifecycle. Because of the current Hacking Team collaboration, each of them has their own point of skill, able to penetrate the security central, extract key corporate assets, protect such information without ...

Research and realization of access control subsystem based on attribute encryption in cloud storage Sun Youpeng because of the complexity of the cloud environment, the various entities are not trusted, so password access control technology to prevent user data leakage is the most direct means. In recent years, the academia has introduced the attribute-based encryption system in the access control, which is a method developed on the basis of identity encryption. This paper chooses the access control technology in cloud storage as the research direction, and deeply analyzes some problems of access control technology based on attribute encryption. Including the lack of access policy expression, permission to withdraw ...

Many studies have shown that there is a big divergence between cloud service providers and their customers about who should be responsible for the security of customer data: Suppliers put their responsibilities in the hands of customers, but customers generally disagree. 　　 According to a survey conducted by the Ponemon Institute last year, seven of the 10 cloud service providers gave customers the security responsibility for their data, and only 30% of the customers agreed. Pravinkothari, chief executive and founder of cloud security provider CipherCloud, said, "The supplier is not responsible if you host the data to the cloud ...

The introduction of cloud computing makes the integration and sharing of resources increased, about cloud computing, the Internet can see the overwhelming introduction and elaboration, the word is now well-known, and slowly towards the public many areas, and we have been concerned about the data security issues, but more and more prominent. Peng Yu into security experts said that the cloud computing architecture under the mass data and traditional mode of data in different network environment, and its security protection system of course, there are very big differences. To some extent, the traditional protection in the cloud architecture has encountered bottlenecks, which also stems from the cloud era of new data security requirements, so we need a set with the time ...

Design and implementation of cloud storage system based on Homomorphic encryption Song Danxi when the encrypted data stored on the cloud server was developed to a certain scale, the effective retrieval of encrypted data will be an urgent problem, the traditional information retrieval technology has been difficult to meet the needs of massive data retrieval in cloud storage environment, The effective retrieval of cloud encrypted data becomes one of the important research topics that need to be solved at present. In the case of data encryption, the Homomorphic encryption scheme can be used to statistic, analyze and retrieve the ciphertext information, and the result of operation is automatically encrypted.
