I. Preface: With the vigorous development of the Internet network, the application of various networks continue to be new, in our daily life, whether it is a routine or office business, the network for you and I, is already an indispensable part of life! There are many times when we need to use the help of the Internet to disseminate messages or to get the information we want through the Internet. The network is so convenient and easy to use, but have you ever worried: if it is important and extremely confidential information, in the vast network of the sea, how to ensure the security and confidentiality of information? Yes, information security is a very important subject. Internet ...

As a basic technology, data encryption is the cornerstone of all communication security. The process of data encryption is implemented by various encryption algorithms, which provide great security protection at a very small cost. In most cases, data encryption is the only way to ensure information confidentiality. According to incomplete statistics, so far, the public has published a variety of encryption algorithms up to hundreds of kinds. These encryption algorithms can be divided into conventional cryptographic algorithms and public-key cryptography if they are classified according to the same key. In a regular password, the recipient and originator use the same key, that is, the encryption key and decryption key is ...

Design of HDFs hybrid encryption protection Scheme Liang Sheng Qin Song Lei How to solve the security problems in cloud computing effectively is the key to the development of cloud computing industry. Aiming at the security problem of the Hadoop cloud computing system in data sharing, a hybrid encryption protection scheme based on RC4 and RSA is adopted, which is closely combined with the characteristics of the Hadoop cloud computing system in the process of cloud storage data sharing, and it can realize the security sharing of the data, and both the confidentiality and the efficiency. Design of HDFs hybrid encryption protection scheme

According to IDC data, the growth rate of cloud storage services is expected to exceed all other IT cloud services by 2013. Over the next four years, the market for cloud services will grow from $17.4 billion trillion today to $44.2 billion trillion, with the market share of cloud storage growing from 9% to 14%, meaning that the market for cloud storage will be close to $6.2 billion trillion. In China, cloud storage has become a new growth point in the network economy seems to have become a consensus, the current based on the concept of cloud storage network disk market has gathered such as NetEase, Tencent, Dbank (Huawei background) 、...

Recently, the user account of a certain electric dealer website is stolen brush once again to push the information security question to the Thunder wave above. In fact, the need for information security, not only individuals, enterprises more. 　　Concerns about security rules and data leaks have become an important obstacle for companies to adopt cloud storage platforms. Network disk, as a convenient and efficient cloud storage tools, although increasingly subject to the attention and affirmation of enterprise users, but security has always been the most important factor for enterprise users. Therefore, when the enterprise considers using the network disk to manage the data, it is necessary to examine the selected network disk from different angles.
