The invention discloses an incredible cloud center batch resource sharing method based on an exclusive or operation and chaos. In the method, a client A uses an initial secure single sign-on method which is disclosed by the invention and based on a block chain zero-knowledge proof. The method disclosed by the invention is as follows: a central authentication system distributes one globally uniqueidentification for each subsystem; the central authentication system generates one set authorizing accesses to the subsystems for each user; the central authentication system generates one globally unique session token for each user passing login authentication; a user A submits a user name and a password to the central authentication system and applies for the login authentication; the central authentication system verifies the user A; and when the user A accesses a subsystem B, the subsystem B finds a corresponding account in a shared storage area according to a Hash address provided by theuser A and performs verification on the user A according to the following steps. The method disclosed by the invention utilizes the basis of the block chain zero-knowledge proof, the subsystems do notneed to acquire true user information and can judge whether a user has a sign-on right, and the single sign-on security problem in an incredible environment is solved.
