Physical smart card with virtual smart cards and configuration method of virtual smart card

Abstract

The invention provides a physical smart card with virtual smart cards and a configuration method of the virtual smart cards. The physical smart card comprises a hardware layer, an operating system layer, a virtual smart card management layer and a plurality of the virtual smart cards; and the virtual smart card management layer comprises a hardware virtual module, a virtual smart card manager, a configuration service module and a security mechanism module, wherein the hardware virtual module is used for virtualizing a hardware device; the virtual smart card manager is used for distributing hardware resources of the virtual smart cards; the configuration service module is used for providing control information for establishment and maintenance of the virtual smart cards; and the security mechanism module is used for setting the access authority of the virtual smart cards. The configuration method comprises the following steps: after the physical smart card works, running the virtual smart card management layer; judging whether the received external command is the command for establishing new virtual smart cards by the physical smart card; if yes, verifying safe information; and finally setting configuration information of new virtual smart cards in the virtual smart card manager after passing verification. By using the method of the invention, the production cost of the physical smart card with the virtual smart cards can be lowered, and parallel issuing cards from a plurality of card issuers is facilitated.

Description

technical field [0001] The invention relates to a physical smart card, especially a physical smart card configured with multiple virtual smart cards and a method for configuring virtual smart cards in the physical smart card. Background technique [0002] Smart cards have been widely used in many fields, such as SIM cards for mobile phones in mobile communication systems, debit or credit cards for bank deposits and withdrawals, bus cards for public transportation, and social security cards for recording social security information. Most of the above-mentioned smart cards can only be used as a single type of card, such as a SIM card or a bus card, which often leads to the need for individuals to carry a large number of smart cards, which is not only not conducive to people's carrying, but also not conducive to people's preservation of multiple smart cards. And management, bring a lot of inconvenience to people's use. [0003] Therefore, some existing smart cards are provided...

Problems solved by technology

Like this, the hardware equipment of physical smart card is more, has increased the production cost of physical smart card greatly

[0006] At the same time, the above-mentioned smart card can only run one virtual smart card at a time, that is, when the physical smart card is used as a SIM card, it cannot be used for a bus card at the same time, that is, the user cannot use the physical smart card to make a phone call while swiping the card on the bus. inconvenience to the user

[0007] Moreover, this kind of smart card uses hardware to safely isolate multiple virtual smart cards, that is, it is realized by using two central processing units with different purposes. The hardware device of each physical smart card is fixed, and there are compatibility and card issuance standards. The problem is that it is difficult for multiple different issuers to set their own virtual smart cards on the same physical smart card. The above-mentioned smart cards cannot solve the problem of how multiple different card issuers issue their own virtual smart cards safely, equally and independently
