Embodiment Construction

[0017] In the following, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] exist figure 1 In the dual operating system smart card architecture shown, the application data related to the network application of the virtual machine connected to the JAVA card has to be transmitted to the security domain and processed with the participation of the security domain. Therefore, the transmission of application data is delayed , and due to the limitation of its own conditions in the security domain, the computing power is not high, which limits the performance of the entire smart card.

[0019] Considering that the connected version of the JAVA card virtual machine is mainly oriented to network applications, it has high performance requirements such as computing power and storage capacity, but does not have high requirements for security. On the basis of separation of applications with different performance re...

Abstract

The invention relates to a smart card and an application data processing method. The smart card comprises a security domain and an application domain, wherein the security domain comprises an on-chip operating system, a standard-version JAVA card virtual machine operated on the on-chip operating system, a JAVA card runtime library and a standard-version JAVA card application program; and the application domain comprises an operating system, a virtual machine operated on the operating system, a JAVA card runtime library and a connection-version JAVA card application program. The smart card and the application data processing method can reduce the transmission waiting time and the communication delay of application data and improve the application performance of the smart card under the condition that the system safety of the smart card is not reduced and an extra cost is not increased.

Description

technical field [0001] The invention relates to smart card technology, in particular to a dual operating system smart card and an application data processing method. Background technique [0002] As an important tool for identification and security authentication, smart cards have been widely used. In particular, the combination of JAVA technology and smart card technology makes smart cards more and more widely used. This kind of smart card is often called a JAVA card because it can support JAVA virtual machines and various operating platforms. The traditional JAVA card only supports the JAVA card virtual machine of the Standard Edition (Classic Edition), which is mainly used for security authentication and identification. [0003] With the launch of the 3.0 Connected Edition (Connected Edition) JAVA card virtual machine specification, the JAVA card begins to carry more services and realize more functions. The connection version is completely different from the standard ve...
