Encryption Using Public Key

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 ...

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 ...

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 ...

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 ...

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 ...

Certification (authentication) means that the user must provide proof of who he is, an employee, an agent of an organization, a software process (such as a stock trading system or a software process for a Web ordering system). The standard method of authentication is to figure out who he is, what characteristics he has, and what he knows to identify his things. For example, the system stores his fingerprints, and when he accesses the network, he must provide his fingerprints on an electronic fingerprint connected to the network (which prevents him from using fake fingerprints or other electronic information spoofing systems) and allows him to access the system only if the fingerprint matches. More ...

Data security has been a source of concern since 2005, when Bank of America encrypted tapes were lost, resulting in a large disclosure of customer data. Before that, some of the bank's system administrators thought that tape encryption devices were too expensive, and some administrators thought that data encryption was like insurance, not the first thing to do, and that some administrators ran aground because they didn't know whether to buy backup software or buy security software. The US bank leaked customer data in violation of local law, but the Specter-leahy Law stipulates safe data and passenger ...

As an important means of protecting information confidentiality, integrity and non-repudiation, encryption and digital signature are widely used in various information and communication situations. At present, there are many commercial encryption and digital signature products, such as commercial software PGP (pretty good Privacy). In addition, there are free encryption and digital signature software in the open source repository, the most recognized being GPG (GNU Privacy Guard). GPG is a completely free, source-code-compliant software product that is completely compatible with PGP. Today, GPG has ...
