Problems solved by technology

[0004] In the existing technology, the dynamic token does not need to be connected to a computer, but it is easy to be peeped by others or used by phishing websites; the USB Key has a digital certificate to participate in the use process. Although it has certain security, the encrypted data transmission process is still difficult. It may be tampered with by hackers, revealing user privacy, and there are security risks for online shopping and payment

Embodiment 1

[0068] Embodiment 1 of the present invention provides a working method of a multifunctional smart key device, the smart key device includes a smart key module (USBkey module) and a dynamic token module (OTP module), such as figure 1 As shown, the method of this embodiment includes:

[0069] The smart key device is connected to the host computer and powered on for initialization:

[0070] see figure 1 , when the OTP module is awakened, perform step 101 to step 103:

[0071] Step 101: The OTP module waits to receive the PIN code input by the user, and judges whether the PIN code is received within the preset time, if yes, then executes step 102, otherwise the OTP module state is set to the unverified PIN code state, and the OTP module sleeps. waiting to be awakened;

[0072] In this embodiment, when the smart key device is reconnected to the host computer or when the smart key device receives the trigger information that the power button is pressed, the OTP module is woken up...

Abstract

The invention discloses a working method of a multi-functional intelligent secret key device and belongs to the field of information security. The multi-functional intelligent secret key device comprises an OTP (One Time Password) module and a USB (Universal Serial Bus) key module. After the multi-functional intelligent secret key device is electrified, the OTP module waits to receive a PIN (Personal Identification Number) a user inputs and performs verification when the PIN is received and the USB key module waits to receive instructions which are sent from an upper computer, communicates with the OTP module according to the received instructions, returns communication results to the upper computer and continues to wait to receive instructions. The multi-functional intelligent secret key device is independently utilized as an OTP when being offline. According to the scheme of the working method of the multi-functional intelligent secret key device, one time verification can be automatically achieved, the using trouble is avoided, and the safety of equipment is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a working method of a multifunctional intelligent key device. Background technique [0002] As the Internet is more and more widely used, online banking, also known as online banking, has become an integral part of the overall strategy of financial institutions. In recent years, the number of users of online banking has increased dramatically, and has maintained a stable momentum of development. While it provides convenient services for the majority of users, it also exposes potential safety hazards that cannot be ignored. [0003] Banks have taken actions to address security risks. At present, there are generally two methods for user identity authentication in multi-channel applications. One is to use dynamic tokens as a password generation device for logging in to online banking and completing data transmission; the other is an application comparison. The most widely used o...
