Embodiment 1

[0055] figure 1 It shows a schematic flow chart of the implementation of the method for loading the key of the financial self-service device provided by Embodiment 1 of the present invention, and the executive body of this embodiment is the financial self-service device. like figure 1 As shown, the method for loading the financial self-service device key may specifically include the following steps.

[0056] Step S101: Call the PIN pad according to the logged-in account information to generate an asymmetric key pair, the asymmetric key pair includes a public key and a private key, and save the private key in the PIN pad.

[0057] Exemplarily, the administrator logs in to the self-service terminal transaction system of the financial self-service device, enters the administrator interface, and the self-service terminal transaction system invokes the password keyboard to generate an asymmetric key pair according to the logged-in account information, and the asymmetric key pair i...

Embodiment 2

[0073] figure 2 It shows a schematic flow chart of the implementation of the method for loading the financial self-service device key provided by Embodiment 2 of the present invention, and the execution subject of this embodiment is the server. As shown in the figure, the method may include the following steps:

[0074] Step S201: Receive the master key application request containing the public key sent by the financial self-service device; the public key is generated by the financial self-service device by calling the password keyboard according to the logged-in account information;

[0075] Step S202: use the public key to encrypt the master key, and send the encrypted master key to the financial self-service device.

[0076] like image 3 As shown, the use of the public key to encrypt the master key includes:

[0077] Step S301: Send a verification code to the mobile terminal corresponding to the account information.

[0078] Exemplarily, the server sends a verificatio...

Embodiment 3

[0088] Please refer to Figure 4 , which shows a structural block diagram of the device for loading a financial self-service device key provided in Embodiment 4 of the present invention. The loading device 40 of the financial self-service device key includes: a generating module 41 , a first sending module 42 , a first receiving module 43 and an importing module 44 . Among them, the specific functions of each module are as follows:

[0089] The generating module 41 is used to call the PIN pad according to the account information logged in to generate an asymmetric key pair, the asymmetric key pair includes a public key and a private key, and the private key is stored in the PIN pad;

[0090] The first sending module 42 is configured to send a master key application request containing the public key to the server;

[0091] The first receiving module 43 is configured to receive the encrypted master key sent by the server;

[0092] An import module 44, configured to import the...

Abstract

The invention is suitable for the technical field of financial self-service equipment, and provides a key loading method and device for the financial self-service equipment, financial self-service equipment and a server. The method comprises the following steps: calling a cryptographic keyboard to generate an asymmetric key pair according to logged-in account information, wherein the asymmetric key pair includes a public key and a private key; storing the private key in the cryptographic keyboard; sending an application master key request including the public key to the server; receiving an encrypted master key sent by the server; and loading the encrypted master key into the cryptographic keyboard. Through adoption of the key loading method and device for the financial self-service equipment, the financial self-service equipment and the server, the function of automatically encrypting the master key is realized; the hidden danger caused by manual import is avoided; and the security ofthe master key is ensured. The key loading method and device have relatively high practicability and usability.

Description

technical field [0001] The invention belongs to the technical field of financial self-service equipment, and in particular relates to a method and device for generating keys of financial self-service equipment, financial self-service equipment and a server. Background technique [0002] The current financial self-service equipment generally uses three sets of keys when conducting business transactions: Master Key (master key), Pin Key (Pin key is used to verify the legitimacy of transaction data) and Mac Key (Mac key). The key is used to verify the validity of the message), and the Master Key is mainly used to decrypt the Pin Key and Mac Key issued by the server, so the security of the master key is very important. There are currently two ways to generate master keys commonly used by banks: [0003] First, plaintext mode: Divide the master key into two or three groups of 16-bit or 32-bit data, and import these data into the PIN pad of the self-service device through the adm...
