This application relates to a resource access
system and a resource
access method. The
system includes: a network range platform, an
authentication center, and multiple business systems; each business
system, in response to a user's access request, redirects to the login interface of the network range platform; the network range platform redirects the login request to the
authentication interface of the
authentication center; the authentication center, upon successful authentication, redirects to the network range platform; the network range platform generates a service
ticket, enabling the user to access the business systems using the service
ticket; each business system, based on the service
ticket and request signature, generates and sends a
verification request to the network range platform; if the service ticket and request signature pass validity
verification, the network range platform returns
user information to the business systems, enabling the business systems to create a local session and configure access identification information based on the
user information, allowing the user to access the resources of the business systems based on the access identification information. Using this system improves resource access security.
