Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0027] like figure 1 As shown, a mobile terminal payment password transmission system includes a mobile payment module 1, a security payment module 2, a payment platform 3 and a password keyboard module 4, and the security payment module 2 has a built-in authentication module 21 and a financial payment module 22. The payment platform 3 has a built-in encryption module 31 . The mobile payment module 1 is used to call the PIN pad module 4 to generate an authentication request message of the secure payment module 2 . The payment platform 3 is used to receive the authentication request message from the password keyboard module 4, and authenticate the secure payment module 2, wherein the encryption module 31 generates and encrypts an authentication script according to the authentication request message. The secure payment module 2 rechecks the pa...

Abstract

The invention discloses a mobile terminal?payment password?transmission system and a method, and relates to the field of mobile payment. The payment password?transmission system comprises a mobile payment?module,?a payment platform, a safety payment?module, and a password keyboard module for inputting a payment password. According to the payment password?transmission method, the safety payment?module and the payment platform are mutually authenticated and an authentication key is generated; the payment password is inputted via the password keyboard module and uses the authentication key for encryption; decryption and encryption again are carried out via the safety payment?module, a payment password ciphertext is formed to be transmitted to the password keyboard module, and the password keyboard module transmits the payment password ciphertext to the mobile payment?module for use. During the payment password use process, the mobile payment?module can not touch a payment password plaintext, and the risk that the payment password is leaked can thus avoided.

Description

technical field [0001] The invention relates to the field of mobile payment, in particular to a mobile terminal payment password transmission system and method. Background technique [0002] How to implement a secure payment process on a mobile terminal, especially to protect the secure transmission of a user's payment password, has always been an important research topic in the field of mobile payment. Generally speaking, using a secure payment device to encrypt and protect the payment password has high security. After the payment password is entered through the software keyboard of the mobile terminal, the mobile terminal transmits the payment password to the secure payment device for encryption and generates relevant transaction messages. Generally, the mobile terminal software keyboard will use the built-in keyboard of the mobile terminal operating system to allow the user to input the password. At this time, the password is in plain text without any encryption. Due to ...
