Problems solved by technology

[0005] The inventor found that the security domain management method provided by the prior art has at least the following problems: since the key of the auxiliary security domain created on the smart card is provided by the operator and the key appears in the operator server in plain text, Moreover, the operator's server can obtain the ciphertext of the key so that the plaintext can be deduced from the key and ciphertext. Therefore, this security domain management method has potential security risks.

Abstract

The invention discloses a security domain management method and a security domain management device, which relate to the technical field of data security and aim to solve the problem of relatively lower security in the mobile payment of a user in the prior art. The technical scheme provided by the embodiment of the invention comprises that: an operator server establishes au auxiliary security domain in a smart card to establish connection between the smart card and a third-party server; the third-party server generates an initial key of the auxiliary security domain, and encrypts the initial key by using a communication key of the auxiliary security domain to obtain a cipher text, wherein the communication key is preset in the smart card and the third-party server, or the communication key is temporarily generated by the smart card and the third-party server; the third-party server transmits the cipher text to the smart card; and the smart card decrypts the cipher text by utilizing the communication key to obtain the initial key. The embodiment of the invention is applicable in the field of mobile payment.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a method and device for managing a security domain. Background technique [0002] The continuous development of financial payment technology and the large-scale commercialization of the third-generation mobile communication technology (3rd-generation, 3G) have accelerated the cross-integration of the financial payment industry and the mobile communication service industry, and mobile payment has gradually emerged. The current mobile payment mainly refers to mobile payment by mobile phone, that is, commercial activities such as payment, shopping, bank transfer and so on carried out wirelessly with the help of mobile phones. Smart cards are recognized by operators for their open architecture and good business expansion capabilities, and are widely used in the field of mobile payment. [0003] Multiple applications can be installed on the smart card. In order to ensur...
