Two-step authentication is used in many validations. If on the mobile client, if you use a computer, each time you have to take out the phone, manually entered. And worry about being out of date. Efficiency is not very high.
I am now dealing with

(for example, if a margin request is extracted during the nth period, and the authenticator is added to the authenticator

It may be someone who is set up for all the people on duty.So last night I was wondering why Charon can't set a password for legitimate users and services?

When the service receives a ticket from the user, it can use this passwordVerify the legality of the user.Euripides: Wait a minute. Charon How to send two copi
problem? In fact, there is no problem. Because client B claims that it is Client A, KDC uses the master key derived from the password of Client A to encrypt the session key, therefore, the party that truly knows the password of Client A will obtain the session key through decryption.
Iii. Introduce authenticator-provide evidence to prove Validity
Through the above process, the client actually obtains two sets of information: one is the session key
/session key: Because packets encrypted by long-term key cannot be used for network transfer, we use another short-term key to encrypt the data that needs to be transmitted over the network. Since this key is only valid for a period of time, even if the encrypted packet is intercepted by a hacker, the key has already expired when he calculates the key.
Second, the introduction of key distribution:kserver-client from whereAbove, we discuss the basic principle of Kerberos authentication: to a
) Identifier: A byte that is used to match the request and reply packets.(3) Length: Two bytes representing the length of the RADIUS data area (including code, Identifier, Length, Authenticator, Attributes) in bytes, minimum 20, and maximum 4096.(4) authenticator:16 bytes, used to verify the server-side response, and also for user password encryption. The shared secret of the RADIUS server and the NAS (GKFX
passwords, or providing a set of private keys pointing to the public keys on the server for authentication. By default, most Amazon EC2 instances use the following method for user authentication: when you start your EC2 instance for the first time, the system will require you to assign a key pair to it as an optional project. In addition to the user name, AWS also assigns a PEM file to the key pair to verify with the server and enable an SSH session.
In today's article, we will discuss security
service then creates a TGT that includes the user information and the logon session key. Finally, the authentication service encrypts the TGT with its own key and passes the encrypted session key and the encrypted TGT to the client.
Client from TGT Request server Access . The client decrypts the logon session key with its long-term key (that is, the password) and caches it locally. In addition, the client stores the encrypted TGT in its cache. When accessing a network service, the client sends

Betting consensus
Casper introduced a fundamentally new concept to the open economic consensus as its foundation: betting consensus. The core idea of a betting consensus is simple: provide the validator with an opportunity to bet which block will be finalized for the verification person. The betting on a block x here is a deal, in all chunks of the world where X is processed, the reward is given to the authenticator
the new "Access-Request": "Access-Accept", "Access-Reject", or "Access-Challenge ".
If all the requirements are valid, RADIUS returns an "Access-Accept" response, including the service type (SLIP, PPP, Login User, etc.) and its ancillary information. For example, for SLIP and PPP, The response includes IP addresses, subnet masks, MTU, and packet filtering information.
Data Packet Structure
The RADIUS packet is encapsulated in the Data field of the UDP datagram, And the destination port

Background: Two-factor authentication (abbreviated as: 2FA, hereinafter referred to as 2FA), where it is the second re-authentication of SSH. 2FA refers to a method of authenticating a user with both a password and a biometric symbol such as a credit card, SMS phone, token, or fingerprint. Through two different authentication procedures, can reduce the risk of password leakage, greatly improve the security of Linux system!First, pre-configuration preparation 1, to prepare a running OpenSSH serv
