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 ...

Companies are moving more data to cloud computing than ever before, covering many different types of service patterns. As the sensitivity and importance of moving into cloud computing data grows, security experts are actively seeking to use cryptography to protect such data, and the technology they use is the technology that they have been using and trusted for years in their data centers.   　　However, in some cases, this goal is not easy to implement, or you need to use a number of different methods and tools, especially for encryption key management. In this article, we will explore the current ...

From a technical point of view, the blockchain involves a variety of fields, including distribution, storage, cryptography, psychology, economics, game theory, network protocols, etc. The key technologies that are currently considered to be resolved or improved are listed below. point. Cryptographic authentication technology How to prevent transaction records from being tampered with? How to prove the identity of the counterparty? How to protect the privacy of both parties to the transaction? Cryptography is an effective means of solving these critical problems.

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 ...

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 ...

This article mainly introduces some principles and background knowledge about PGP implementation. Other documents on the installation and use of PGP refer to other documentation provided with this article. PGP pretty-Privacy 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 seen before, and you don't need any confidential channels to pass the secret.

The use of security programs does not guarantee that your communication is secure. Even if you install one of the safest locks on the front door, thieves can still crawl in through the open window. Also, even with PGP, your computer may still be vulnerable. There are many famous attacks on PGP, and the following sections describe these attacks. However, these are by no means a complete list. Future attacks are likely to compromise all public-key cryptography technologies. This checklist just gives you an idea of what you need to do to protect your communications. 1. The most direct attack on PGP by brute force attacks is the key used by brute force attacks. Because...

ASCII Armor ASCII encoding, encoding binary files with 7bits of display ASCII code, which can be passed in only 7bits-supported emails. The MIME BASE-64 encoding is used in PGP. ciphertext ciphertext; Encrypted later information, generally unrecognized. Cryptanalysis analysis of cryptography, from the point of view of cryptography to find a loophole and attack it, PGP in cryptography is still quite solid. Even Hack ...

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...
