Abstract
A method for authorizing access includes generating a public identity parameter and a private identity parameter for each server, and using the public identity parameter of a first server indicated by a first credential from a resource owner to perform identity encryption on the first credential and a first random parameter so as to generate and transmit a first request message to the first server. The private identity parameter is used to decrypt the first request message. The public identity parameter of a second server indicates by the second credential to perform identity encryption on the second credential and a second random parameter so as to generate and transmit a second request message. The second server uses the private identity parameter to perform decryption on the second request message, and the method determines, according to the decrypted second credential, a resource to be provided to the client.
