Authentication Key Generator

Authenticated key agreement protocol based on hierarchical identity Cao Chenlei Liu Mingxi Zhang Ju Yang Yixian The current Identity-based Authentication Key agreement protocol is a trusted third party with a single private key generator (PKG), but it is difficult to meet the requirement of identity layering registration and authentication. This paper reconstructs the constituent elements of the private key based on the hierarchical Identity Encryption (Hibe) system. A authenticated key agreement protocol based on hierarchical identity is proposed by using bilinear mapping on elliptic curve multiplication cyclic group, which provides a secure session key bargaining machine for cloud entities belonging to different levels.

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 ...

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 ...

Although "cloud computing" at home by many manufacturers in the pursuit of numerous vendors, but often are wool, the security of cloud computing has become an important obstacle to development, especially some enterprises, still for the information stored in the "cloud" lack of confidence. If the issue of information security is considered a war, then in this battle to maintain information security, everyone in society becomes a cyber-security fighter guarding their own domain security. Although "cloud computing" at home by many manufacturers of the pursuit, but often are wool, cloud computing security issues become ...

In the modern information society, when the email is popular, the security problem is also very prominent. In fact, the process of e-mail transmission is the process of repeated replication on the network, the network transmission path is uncertain, it is easy to be unknown identity of the theft, tampering, and even malicious destruction, to send and receive both sides trouble. Information encryption to ensure the security of the transmission of e-mail has become an urgent demand for the vast number of e-mail users. The appearance and application of PGP solves the problem of secure transmission of e-mail well. Combining the traditional symmetric encryption with the public key method, we have two ...

Cloud computing is a new internet based computer technology, it integrates the distributed computing, utility computing, parallel Computing, grid computing, networked storage, virtualization and other traditional computer and network technology, forming a set of new standards and models, "cloud computing" concept is rapidly applied to the production environment, all kinds of "cloud computing" The scope of service is growing and its influence is incalculable. In layman's terms, cloud computing is a way for you to give all data processing tasks to the network, and the Enterprise Data Center is responsible for processing the data tasks on the client's computer so that you can pass a data ...

"Sadie Network News" Although "cloud computing" in the domestic by many manufacturers of the pursuit, but often are wool, the security of cloud computing has become an important obstacle to development, especially some enterprises, still for the information stored in the "cloud" lack of confidence. If the issue of information security is considered a war, then in this battle to maintain information security, everyone in society becomes a cyber-security fighter guarding their own domain security. It is understood that at present, China's information security areas are mainly related to things, mobile internet, cloud computing system security and the three network integration ...

Cloud computing technology to provide users with multi-functional, personalized service at the same time, it is also easy to cause the user's personal privacy data leaked. The application provider stores the data information in the data center of a third-party cloud computing service provider, and users access the data information through a variety of third-party excuses provided by the cloud services provider. In the process of data access, cloud computing service providers play a key role in the effective protection of users ' privacy data security has a direct impact. In the Cloud Computing Application service mode, the user privacy data and the traditional personal privacy information have a big difference, how to effectively protect the user's personal privacy ...
