Encryption/decryption system and method based on space motion

Abstract

The invention discloses an encryption / decryption system and method based on space motion. The encryption / decryption system mainly comprises a motion sensing module, a private key generation module, an encryption module, a decryption module, a control module and a private key storage module, wherein the motion sensing module is used for receiving direction data generated by a direction sensor hardware; the private key generation module is used for processing the direction data and converting the direction data into a vector which is used as a user private key; the encryption module and the decryption module are used for completing the encryption and decryption process of the information by adopting the data encryption standard (DES), AES (Advanced Encryption Standard) and other optional symmetrical private key systems; the control module is used for controlling the system and calling other modules for intentions of different users; and the private key storage module is used for storing different generated private keys according to the information of different users in a ciphertext form. By utilizing the system and the method, the quick private key generation and encryption / decryption technology is provided by utilizing the motion sensing capability of portable equipment, such as a gyroscope and an acceleration transducer, and a user can finish the encryption / decryption operations on the information by utilizing the private keys.

Description

technical field [0001] The invention belongs to the field of information security, and specifically relates to a portable device with a gyroscope and an acceleration sensor. A key is generated by detecting the motion attribute of the portable device, and a symmetric encryption algorithm is used to encrypt the key, and then recorded again The way the device moves, the verification of the key and the decryption of the information are performed according to the similarity of the attributes of the two movements.
