Data Encryption Error

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 ...

First, generally speaking, encryption is the shell we often consider, an executable file, how to encrypt to be safe? The usual means is the Packers. The working principle of the Shell tool is to encrypt the code and data of the executable file as data storage. The generated target file entry code is the anti-trace code prepared by the Packers software. After a long code, the code of the original executable file and the Data section restore, and then jump to the original entrance, continue to run. The disadvantage of this is that no matter how strong your encryption, anti-tracking code more cattle, as long as a running, in ...

First, des algorithm in 1973, the U.S. National Bureau of Standards, in addition to the Ministry of Defence of other departments of the computer system data encryption standards, on May 15, 1973 and August 27, 1974, two times to the public to solicit encryption algorithm announcements. The purpose of the cryptographic algorithm (commonly referred to as the DES cipher algorithm requirement) is the following four points: ☆ provide high quality data protection to prevent unauthorized disclosure and undetected modification of data; ☆ has a considerable complexity, so that the cost of deciphering more than possible benefits, but also easy to understand and master;

"Cloud" This word in recent years has been fired hot, in the information security sector, "cloud" is a big darling, the enterprises have been among the ranks of the cloud. Because, the advent of cloud technology does bring the modern enterprise very big convenience. However, with the benefits of the accompanying, of course, there is a reluctance to touch the information security risks. Since enterprises want to take advantage of the benefits of cloud technology, it is natural to find ways to solve the cloud security risks, reduce the risk faced by enterprises. 　　The following is to share the cloud of the server's 7 major security secrets, so that enterprises targeted security protection. Server data Security 7 big secret ...

[Guide] existing http://www.aliyun.com/zixun/aggregation/13793.html "> Cloud service Providers can provide a foundation encryption key scheme to protect cloud-based application development and services, Or they leave these protections to their users. When cloud service providers develop programs that support robust key management, more work needs to be done to overcome the barriers that are being used. The criteria under development should be resolved in the near future, but the work is still ongoing. Cloud computing ...

Compression and shelling the first section PE file format PE tutorial 1:PE file format list PE means Portable executable (portable actuator). It is the executable file format with the WIN32 environment itself. Some of its features are inherited from the Unix Coff (Common object file format) files format. "Portable Executable" (portable executable) means that this file format is cross win ...

Existing problems in the 20th century, the protection of important documents by enterprises mainly by the use of safes to save, and send people to protect. In the 2l century, enterprises began to fully implement automated office, computer networks become information processing and storage tools. However, because of the sharing and diffusion of the computer, the information can be easily leaked and stolen in the process of processing, storing and transmitting. According to the survey, up to the first half of 2007, rising company to accept the help of the injured user has reached more than 100,000 people. Then the information security technology follow-up, the Enterprise's information safety hidden more attention ...

"Data has penetrated into every industry and business functional area today, becoming an important factor in production." The excavation and application of massive data indicates a new wave of productivity growth and consumer surplus. 　　The arrival of the big data age was first proposed by McKinsey, a world-renowned consulting firm. Indeed, this is the age of large data. On Wall Street in the south of New York Manhattan District, investment banking sold shares based on popular sentiment, and hedge funds analyzed the sales of corporate products based on customer reviews at the shopping site; at the very beginning of the World Cup in Brazil, Google [micro-blog] Cloud computing flat ...

At first glance, the impact of large data on the datacenter is like another high-performance application that requires more processing power, more http://www.aliyun.com/zixun/aggregation/17325.html "> Storage space, And a more high-performance network. In short, this seems to be another burden for the datacenter. In fact, however, large data is not just a tool for business analysis, it can also be a useful tool to help improve data centers. Better IT Security ...

Teradata Company CTO Baoliming (Stephen Brobst) May 22 News, a large data maker Teradata Day of the company CTO Baoliming (Stephen Brobst) in the "2013 Teradata Big Data Summit," said Tencent Technology, Cannot blindly negate seemingly useless data, they also contain value, but have not found the value embodiment means, can use Low-cost storage server to retain. Data are valuable how to distinguish the value of large data? Baoliming said that ...
