Abstract

The invention relates to an encrypted method and system of the digital wireless data communication networks (10, 11) for encrypting the data encryption to one-time pad, which is characterized in that: the data communication networks (10, 11) comprise at least two terminal devices (A, B), terminal devices (A, B) are used for managing the index encrypted key (S_N) set, wherein, the first terminal equipment (A) is at least an engine, and the second terminal equipment (B) is at least a receiver. The data encryption is suitable for grading processing in the first terminal equipment, wherein, the encrypted key index (N) (302-306, 702) is selected, the encryption key defined by the selected encrypted key index (N) is utilized to encrypt (308, 704) for the data wait for sending, and is used to send the encrypted data (RM) to the second terminal equipment (B) (309, 705), wherein, the encrypted data (RM) (401, 706) is received on the second terminal equipment (B), and the key (S_N) indicated bythe selected encrypted key index (N) is utilized to decrypt (404, 709) the encrypted data (RM). The encrypted key index (N) except the encrypted data (RM) is sent to the terminal equipment (B). The data communication networks (10, 11) also comprise a particular server terminal equipment (13.1) which is planned into a management index encrypted key (S_N) set and is distributed to the terminal devices (A, B). The invention also relates to a piece of corresponding server terminal equipment (13.1).

Description

technical field

[0001] The present invention relates to a method for arranging data encryption as a one-time pad garbled encryption method in a digital wireless data communication network, wherein the data communication network includes at least two terminal devices, the terminal devices are used to control the index encryption key set, and the first in the terminal device A terminal device is at least a transmitter, a second terminal device is at least a receiver, and data encryption is suitably performed in stages in the first terminal device, wherein

[0002] - select the encryption key index,

[0003] - encrypt the data to be sent by encrypting the data to be sent with the encryption key defined with the selected encryption key index, and

[0004] - Send encrypted data to the second terminal device

[0005] and correspondingly in the second terminal device

[0006] - receive encrypted data, and

[0007] - Decrypt the encrypted data by using the selected key indicated b...

Embodiment Construction

[0038] Figure 1 is a schematic diagram of an example of an embodiment of a system according to the invention. The system and method according to the present invention involves arranging data encryption in a digital wireless data communication network 10, 11 according to a one-time pad encryption model. The data communication network 10, 11 may be a wired network, such as an IP network (eg Internet, Intranet, Local Area Network), or wireless (eg WLAN, CDMA, TDMA, FDMA, Bluetooth).

[0039] The data communication network 10, 11, wireless in the case shown as an example, comprises at least two terminal devices A-D communicating with each other, wherein one terminal device A is used at least as a transmitter and the other terminal device B is used at least as a receiver machine. The communication between the terminal devices A, B may eg be directly in a data format, such as SMS messages, or e-mail, or indirectly in a data format, such as encoded speech.
