Uses Of 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 ...

Data encryption, database encryption technology Status quo and future trends? Can the product solutions in this area meet the needs of industry and enterprise users? Firewall is not a problem all of the anti-intrusion network security technology represented by the firewall is not equal to all information security. In the vast majority of information systems, the core data and data are stored in the way of the database, no encrypted database is like a locked file cabinet, for those with ulterior motives, plagiarism, tampering is a breeze. Therefore, the security of database should not be neglected. Database encryption system is to enhance the common relational database ...

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 ...

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 ...

Every day, the world due to software piracy caused by the loss of not less than 50 million U.S. dollars, even in the so-called legal system of the most perfect in the United States, piracy rate of up to 21 (data from IDC). Software piracy has become a major test of the survival of the software industry, and encryption has become a helpless choice. If the anti-virus technology update is driven by the virus manufacturer, then, the software encryption industry is a game with the decryption, but also promote the market demand for the development of the industry. In the initial encryption process, most of the software used by the soft encryption method, the main ...

E-Mail has become the most convenient way of communication in the Internet age, because of the freedom of the Internet, so the security of the mail is becoming more and more prominent. Today, with the popularity of the Internet, e-mail is becoming more and more popular, open a book or magazine newspaper, have an e-mail address, even the ads are marked with e-mail address; this has become a fashion, the most convenient way to communicate in the Internet era, save money, fast. It is because of the freedom of the Internet, so the security of the message is increasingly prominent. e-mail Message delivery, general ...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

The following article is mainly about wireless encryption is commonly used in wireless network encryption protocol, in the actual operation of the widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol two. The widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol. WEP protocol is also called Wired Equivalent encryption protocol, this kind of wireless communication protocol is often those who are eager to produce and sell wireless equipment in a relatively short period of time to put together the informal wireless encryption communication standards, from the current view of this wireless network encryption protocol There are quite a lot of security ...

PGP is a mail encryption software based on RSA public key encryption system. You can use it to keep your emails secret to prevent unauthorized reading, and it can also digitally sign your emails so that the recipient can be sure you sent them. It allows you to safely communicate with people you've never met before, and you don't need any confidential channels to pass the keys. It uses: Prudent Key management, a RSA and traditional encryption of the hybrid algorithm for digital signature of the message digest algorithms, encryption, and so on, there is a good ergonomics design. It's powerful and fast. And...

In modern society, e-mail and file transfer on the network has become a part of life, the security of the message is increasingly prominent. It is well known that the data transmitted over the Internet is usually unencrypted, and if you do not protect your important information, the third party will easily gain your privacy. Another problem is information authentication, that is, how to convince the recipient that the message has not been tampered with by a third person, which requires digital signature technology. PGP is such a product. Pgp--pretty is a Privacy based RSA public key encryption ...
