A complete IEEE 802.1x-based authentication system consists of three parts: the authentication client, the authenticated user, and the authentication server (role.

the IEEE 802 protocol set. It is all called Port-based access control protocol. Based on the advantages of IEEE 802 LAN, it provides a method to authenticate and authorize users connected to the LAN, so as to accept access from legitimate users and protect network security.
802.1x protocol and LAN are seamlessly integrated. 802.1x uses the physical features of the switched LAN architecture to implement device authentication on the lanport. During the authentication process, the lanport either a

Now the project has been on the line for some time, and I want to be able to notify the relevant developers after an exception occurs in the project. I've been looking for a lot of third-party interfaces from the Internet (which costs money) and sending emails to demo. Finally, we chose an implementation that only needs to introduce a jar package and a tool class, no configuration files, and the following tool class code:Packagecom. Evan. Mail;Import Java. Util.

Shiro frame composition to illustrate the processing order within the Shiro certification:1. After the application constructs an Authenticationtoken instance of the end user authentication information, the Subject.login method is called.2. An instance of Sbuject is typically an instance object of the Delegatingsubject class (or subclass) that, at the beginning of authentication, delegates the SecurityManager instance set by the application to invoke the Securitymanager.login (token) method.3, S

When you call axis2 wsdl2java to generate service stubs, if the remote service requires NTLM authentication, the following error occurs:

Realm is a bridge between security and data. It encapsulates configuration information such as Dao, you can specify the connected data source, or you can use other authentication methods, such as LDAP.
Then let's take a look at the detailed architecture diagram:

This article describes how to use javamail to send HTML-format emails through the SMTP server to be authenticated.First, download the implementation of javamail on the sun website, and add your classpath to the implementation of JAF (I don't know why I don't want to put it together.
The code first inherits a class from authenticator, such as smtpauthenticator, which is used for authentication when connecting to the SMTP server.

question (preferably 16 bytes) and transmits it to the user, the user returns a chap response with the chap ID and chap username. NAS then transmits a request to the RADIUS server. In the request packet, the chap user name replaces the user name (User-name), chap ID and encrypted response value replace chap password (chap-password) (attribute 3 ). A random question can be included in the chap-challenge attribute, or if it is 16 bytes long, it can be put into the request authentication code (req

It supports mainstream browsers such as chrome, Firefox and IE, as well as mobile devices such as iPhone, Android, and blackberry, and Google authenticator (GoogleAuthenticator) to import existing accounts and passwords in the browser to the lastpass database.
When you log on, the browser plug-in of lastpass will automatically fill in the information required for logon

In addition, the public key system can also be used for authentication , the following:1, a to b before sending a message, first use a 's private key to encrypt the message, because B only with a 's public key to decrypt the message, so the message can be used for authentication source and data integrity. This can be improved because authentication encryption for the entire message is too computationally time-consuming and storage space. Only a small block of data called a

say, for us, the simplest of a Shiro application: 1, the application code through the subject for authentication and authorization, and subject entrusted to SecurityManager; 2, we need to give Shiro SecurityManager to inject realm, so that SecurityManager can get legitimate users and their rights to judge. as can be seen from the above, Shiro do not provide maintenance users/ permissions, but through Realm let the developers inject themselves. Let's take a look at the Shiro architecture from
