Symmetric Encryption

Describes the use of unmanaged Win32apis encryption to decrypt data before. NET is a very painful thing to do. For the purpose of this cryptographic decryption. NET is configured with a set of classes (and namespaces). Now you have a lot of classes that can protect your data using each of these different algorithms. There are 3 types of encryption methods defined within the. NET Crypttography namespaces. They are asymmetricalgorithm,symmetricalgorithm and HashAlgorithm. All the ...

Q: Suppose two people use symmetric encryption to exchange information, and each time they communicate, the session key is generated, encrypting information using protocols such as SSL that process the session key. In addition, they can exchange information using PGP, a mail encryption software based on the RSA public key encryption system. Which encryption method do you think is more secure in this case, PGP or symmetric encryption? A: It depends on the degree of trust you have in your local environment. Symmetric encryption encrypts all packets between mail servers by using a shared encryption key to ensure that information between systems is not compromised. PG ...

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 ...

There is no doubt that people who understand the technology of data encryption should be able to protect the security of the source of technology. 　　Because of the direct use of data, so that data even if the security crisis lost, was stolen, encryption protection can still guarantee the real content of the data security. But the flexibility of data encryption is the place where people have been criticized. From the initial information encryption is not convenient to transparent encryption, from the beginning of a single encryption to the current Multimode encryption, encryption technology is also constantly improving to cope with the increasingly rich demand for encryption. and the development of data encryption technology is not only this, in order to deal with the more ...

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 ...

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 ...

Http://www.aliyun.com/zixun/aggregation/14111.html, an enterprise-level data analyst company for Hadoop Production management and security software, says it plans to increase encryption at the end of 2013 >zettaset Eric Murray, the security architect who works at Zettaset, says the orchestrator suite of companies managing the Hadoop cluster is being enhanced, including the creation of symmetry based on Hadoop data partition encryption ...

, as cloud technology and large data gradually permeate business and personal life and work, it is easy for people to save and access data anytime, at the same time, the cloud technology is increasing the efficiency of the data security risk, how to ensure that the data security cloud is also a modern information technology development in the "normal" problem, 　　Especially enterprise application data security needs are imminent. However, the problem is grim, but smart software developers are "no fight unprepared", has already prepared the law of protection. such as invoicing industry's Nova-the wisdom of business invoicing, for the modern information by ...

At present, cloud computing development is in full swing, in the market has occupied a large area of heaven and earth. The public cloud as the main form of cloud computing, as a supporting platform, because of its low price and powerful attractive service, more and more of the Community enterprises and institutions began to dabble in this field. 2013, China for a number of large international open the public cloud market door: Microsoft, IBM, Amazon ... While the public cloud is favored, a significant number of people stand firm in the private cloud, which they think is superior to the public cloud. It must be admitted that the public cloud is indeed ...
