Embodiment Construction

[0082] The encryption device 1 includes a keyboard 3, a display screen 2, a microcontroller MCU, and a power supply. The keyboard 3, the display screen 2, and the power supply are respectively connected to the microcontroller MCU, and the microcontroller MCU has a built-in memory and arithmetic unit.

[0083] The two-way authentication method for both parties in a transaction using the encryption device 1 described above, the authentication method includes identity confirmation, and identity confirmation includes the following steps:

[0084] (a) Customer service providers distribute independent encryption devices to dedicated customers;

[0085] (b) The user connects to the server via the Internet or telephone and enters the customer account K;

[0086] (c) The server retrieves the server password Mo and the encryption algorithm Fo indicating the identity of the server according to the customer account K;

[0087] (d) The server generates a random number N, calculates the encryption re...

Abstract

The invention relates to a secure communication device and a method, in particular to a device and a method for sending and receiving a code by adopting a special manner. In the question answering mutual identity and transaction confirmation method and the device adopting the method, the confirmation method comprises identity verification and transaction content confirmation, and has the characteristic of mutual authentication. An encryption device is separated from the outside completely, and has no electronic connecting interface, so that the hacker attack can be avoided, and the device canalso be used in the environment of no personal computer. In the device and the method, not only does a server identify a client in a unilateralism manner, but the client also discriminates the validity of the server through checking the validity of a quenstion and answers the quenstion after confirming the validity of the quenstion only, thereby effectively resisting fishing trap. By adopting themethod and the encryption device, identity verification and electronic transaction can be performed safely in unsafe environments such as an Internet bar, etc.

Description

technical field [0001] The present invention relates to a secure communication device and method, in particular to a device and method for sending and receiving passwords in a special way. Background technique [0002] At present, service agencies usually use three methods for identity and transaction confirmation: static passwords, dynamic passwords, USB password locks and smart cards and other hardware encryption methods. These three methods have their own advantages and disadvantages: the static password is easy to use but extremely insecure, and it is easy to be monitored and invalidated. At present, the methods of using dynamic passwords usually include dynamic passwords sent by short messages, two-dimensional password retrieval cards printed on paper, and the like. SMS dynamic passwords improve security, but there are also problems such as relying on the operator's network to send SMS, being unavailable in areas where SMS is not smooth, and requiring payment to telec...
