Identity authentication method based on power distribution

Abstract

The invention discloses an identity authentication method based on power distribution, which is executed by an authentication server and comprises the following steps: receiving an authentication request instruction sent by a client, the authentication request instruction comprising a user name and a client IP address; in response to the authentication request instruction, querying whether the client is a legal user in a user database according to the IP address of the client; when it is determined that the client is a legal user, generating a random number and sending the random number to theclient as an authentication code, and calculating the user name and the random number through a preset algorithm to generate a first byte string; receiving a second byte string generated by the client in response to the authentication code, comparing the second byte string with the first byte string, determining that identity authentication of the client is passed when it is determined that the first byte string is consistent with the second byte string, sending authentication passing information to the client, and establishing a connection; otherwise, determining that the identity authentication of the client fails, sending authentication failure information to the client, and disconnecting connection.

Description

technical field [0001] The invention relates to the field of electric power distribution identity authentication, in particular to an identity authentication method based on electric power distribution. Background technique [0002] Identity verification / authentication is the process of verifying whether the real identity of the subject is consistent with the claimed identity, which can be divided into authentication between the user and the host and authentication between the host and the host. Identity authentication is the first line of defense for network security, and it is also the most important barrier. Various applications and computer systems in the network need to pass identity authentication to judge whether the current user is legal or not, and to determine the user's identity, so that legitimate users can obtain corresponding information. access rights; access is denied to illegal users. [0003] Traditional identity authentication technology includes simple p...

Problems solved by technology

However, the disadvantage of simple password authentication is that the level of confidentiality is not high, and it is easy to be cracked; the disadvantage of dynamic password is that it is complicated to implement, the application technology is not mature enough, and it is not perfect in solving synchronization problems; the disadvantage of smart card authentication is that it is inconvenient to operate and requires the authentication party It is necessary to carry a smart card, which is not conducive to operation; the disadvantage of biometric authentication is that it needs to enter the biological characteristics of the other party in advance, and only the parties who enter the characteristics are allowed to pass the authentication. Individuals are allowed to operate at the same time, which does not meet the actual business needs and is not conducive to practical applications
