Method for automatically issuing secret key of self-service machine tool

Abstract

The invention provides a method for automatically issuing a secret key of a self-service machine tool. After qualification testing is past, a public key downloading transaction is initiated at a self-service machine tool side, a server side calls a public key interface of an encryption platform to acquire a public key, after the self-service machine tool successfully imports the public key, a keyword keyboard randomly generates a session key and enables the public key to encrypt the session key, the server side calls a main secret key interface of the encryption platform and sends the sessionkey and ciphertext to the encryption platform, the encryption platform generates a master key for the self-service machine tool, the master key is encrypted by using the session key, then the encrypted master key is sent to the server side and then is sent to the self-service machine tool side, and the self-service machine tool side decrypts the master key and the ciphertext by using the session key and stores the master key to the keyword keyboard of the self-service machine tool, so that corresponding information can not be interpreted even if a third party intercepts the master key and theciphertext, safety of a master key issuing process is guaranteed, manpower resources and time are saved, and master key issuing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a method for automatically issuing keys of self-service machines. Background technique [0002] At present, the bank's self-service machine keys are mainly issued by the staff through the key application function of the key management system to generate the key, and then use the key printing function to print out the master key component envelope, and then go to the site manually. The key is injected. [0003] In the process of manual on-site key filling, there are processes such as multi-person distribution of key component envelopes, multi-person entry, and envelope destruction. Therefore, this process requires high management standards and implementation methods, and the process is cumbersome. One machine tool It often takes several days to complete the key distribution, which consumes manpower and time. Contents of the invention [0004] The present i...
