Data Encryption

Data encryption is one of the key technologies to realize network security, this paper first introduces the basic concept of encryption, then focuses on two kinds of the most common encryption technology: private key encryption and public key encryption, and detailed discussion of their characteristics, development and future research direction. Because of the rapid development of Internet, the security of encryption algorithm is paid more and more attention by people. Faced with the potential threat and attack of computer network, a computer network security manager should build a powerful and safe protection means for the network that he has jurisdiction over, which can be done through the following six security levels: patching ...

Public cloud environment, data encryption has become a key means to ensure data security. But when a chip needs to send or receive data stored outside of the chip, it will give the attacker an opportunity to learn about the workload and pinpoint the target. At a MIT press release on July 2, researchers brought a system called Ascend that addresses the security flaws that involve memory access. Ascend through a series of measures to minimize the attackers get from the memory data transfer process ...

Research on storage virtualization document encryption in cloud computing environment Zhang An with the development of network technology, especially the appearance of cloud computing, data documents will be changed from traditional local data to virtualized storage in cloud environment. In this process, the traditional data document encryption method will no longer apply to the cloud computing environment for document storage encryption. Therefore, it is necessary to put forward a new data encryption method suitable for virtual storage environment. In view of the characteristics of storage virtualization in cloud computing environment, it is proposed that the intelligent dynamic encryption and decryption will become the encryption and decryption method of the data document in the virtual storage environment.

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. Be in the cause of

In the historical development of the enterprise data security protection technology, so far, has gone through three development stages. Initial intrusion detection, developed into medium-term antivirus, until now data encryption technology. Enterprise data security protection is a long and tortuous work. In the past decade, the small and medium-sized enterprises involved in the secret information system in accordance with the requirements of the implementation and operation of the security system, and achieved certain results, but there are some problems in the implementation process: the early security measures are too simple, no classification of security levels and levels, the implementation of higher costs. Now, due to the internet ...

Data encryption and decryption are very important in the security field. For programmers, storing user passwords in ciphertext in a database is important to intruders who plagiarize users ' privacy. There are a variety of front-end encryption algorithm can be used for data encryption, decryption, I recommend a simple database-level data encryption, decryption solution. Take the MySQL database as an example, it built the corresponding cryptographic functions (Aes_encrypt ()) and decryption functions (Aes_decrypt ()). Inserts encrypted data into the table insert in ...

Currently, the Hadoop-based big data open source ecosystem is widely used. At the earliest, Hadoop was considered to be deployed only in a trusted environment, and as more departments and users joined, any user could access and delete data, putting data at great security risk.

Domestic online games are no longer homogeneous at present, most of the game in the country are in the "Three Kingdoms", "through" the subject of wandering, the player aesthetic fatigue phenomenon is serious. and recently by the original Rainbow Studio research and development of "Seal God List 3" is breaking the current market situation of Shen Chaotic, Rainbow Studio is now Jinshan seven dust Zhai Division, "Seal the Gods List 3" is its 3 years of the launch of the masterpiece. "The competition is increasingly fierce, only the promotion of technology is the core competitiveness of the development of the game," said Liu Hongbo, deputy general manager of seven dust. "Seal God list 3" not only in the play to achieve innovation, contains cultural details and the quality of the game ...

Cloudera recently released a news article on the Rhino project and data at-rest encryption in Apache Hadoop. The Rhino project is a project co-founded by Cloudera, Intel and Hadoop communities. This project aims to provide a comprehensive security framework for data protection. There are two aspects of data encryption in Hadoop: static data, persistent data on the hard disk, data transfer, transfer of data from one process or system to another process or system ...

ElGamal algorithm can be used both for data encryption and digital signature, and its security depends on the problem of computing discrete logarithm on finite field. Key pair generation method. First select a prime number p, two random numbers, G and X,g, x < P, and compute y = g^x (mod p), the public key is Y, G, and P. The private key is X. G and P can be shared by a group of users. ElGamal is used for digital signatures. The signed information is M, first selects a random number k, K and P-1 coprime, calculates a = g ...
