Description

Security token device and RF module and method of authentication usable in smartphone and PC}

The present invention relates to a security token device, a wireless module, and an authentication method that can be used in a smart phone and a PC.

Recently, with the rapid increase of smartphones, mobile financial transactions using smartphones are attracting attention. At the same time, interest in security measures for mobile financial transactions using smartphones is increasing.

Mobile financial transactions using smart phones have the advantage that they can conveniently carry out financial transactions anytime, anywhere. It is also observed that mobile financial transactions (smartphone banking) using smartphones will outpace financial transactions on existing PCs.

Although regulations on mandatory use of accredited certificates have been eased in online financial transactions (Internet banking) recently, accredited certificates will continue to be used as an important user authentication method in domestic online financial transactions.

Smartphones can be downloaded and installed freely as the user wants the application program like a normal PC. As a result, there is a security risk that can be hacked by programs that contain malicious code like general PCs. Internet banking on existing PCs also have serious security problems that can be copied and leaked at any time. Due to these problems, the Ministry of Public Administration and Security is planning to prohibit the storing of accredited certificates on hard disks from 2013 and to implement the policy of storing accredited certificates in secure security tokens.

 A security token is a hardware device that can safely store and store secret information such as an electronic signature key, and is a hardware device that can not be leaked outside of the secret information.It has a process and cryptographic operation device that can generate an electronic signature key, generate and verify an electronic signature, etc. It is a hardware device. If the certificate is stored and used in the security token, the leakage of the electronic signature key can be blocked at the source to prevent financial security accidents caused by the leak of the certificate.

For security of smartphone banking, there are limitations in applying various security programs such as antivirus program, keyboard security program, anti-phishing program, firewall program applied to internet banking in existing PC to smartphone. In the case of smartphones, unlike general PCs with an open platform (operating system and hardware environment), the platform is independent and diverse for each smartphone manufacturer, making it difficult or fundamentally difficult to convert the various security programs applied to existing PCs for smartphones. It is often impossible to apply. In addition, it is impossible to completely prevent hacking even when the various security programs are applied to a smartphone. Unlike PCs, running multiple security programs on a smartphone with limited hardware performance has a problem of slowing down speed and greatly reducing the utility of smartphone banking. In addition, the public certificate stored in the smart phone, like the public certificate stored in the hard disk of the general PC, there is a risk that the public certificate can be leaked.

As mentioned above, due to the problem of leakage of the certificate that may occur when the Internet banking on the smart phone has become an obstacle to the spread of smart phone banking.

Storing the public certificate in the security token has the effect of preventing the leak of the public certificate. However, if the security token is only able to communicate with a smartphone and cannot communicate with a PC, laptop, tablet PC, etc., when Internet banking is performed on a PC, laptop, tablet PC, etc., the certificate stored in the security token must be copied to the outside. Since it is impossible, there is an inconvenience of having to reissue the certificate every time.

In order to solve the above-mentioned problems, the present invention connects a security token that securely stores a public certificate to a smartphone and prevents a security accident such as leaking a public certificate by using a public certificate stored in the security token when the smartphone is banked. For the purpose of

More specifically, the smart phone external device interface unit such as a microSD connector or a portable digital media interface (PDMI) connector of the smart phone that can be supplied to the outside is supplied with power required to drive a security token, and the smart phone external device interface unit Send and receive data between smartphone and security token. In addition, a smartphone banking application is installed on the smartphone and the user uses the certificate stored in the security token through the smartphone banking application when the smartphone banking. This aims to provide a security token device and authentication method that prevents the leakage of the public certificate that may occur during smartphone banking.

In addition, when internet banking on a PC, laptop, or tablet PC (hereinafter referred to as PC banking), a wireless module (Bluetooth module) is connected to a device interface such as a USB port or a serial port of a PC, laptop, or tablet PC. Wirelessly communicate with each other by Bluetooth, the smartphone and the security token communicates via the smartphone external device interface (microSD or PDMI interface), and when the PC banking, the authentication certificate stored in the security token connected to the smartphone Use Through this, it aims to provide a security token device and an authentication method that prevents the leakage of a public certificate that may occur during PC banking.

It also aims to provide a secure token device, a wireless module, and an authentication method that can be used in both smartphone banking and PC banking as a single certificate.
