基于ARM安全摄像头设计
Design of security camera based on ARM
摘要
Abstract
For information security problems existing in video surveillance,ARM Cortex-A8,USB camera,AES encryption module and TPM are used to design a security video surveillance module. AES is adopted to encrypt video data collected by the video capture terminal. The ciphertext is transmitted to the server through network. For transmission security issue of AES key, the binding function of TPM is utilized for asymmetric encryption on the basis of the trusted computing. The hybrid encryption scheme of symmetric cryptography and asymmetric cryptography is used to achieve symmetric key encryption data and the en-cryption function of symmetric key encrypted asymmetric key. The composition of security video surveillance is briefly intro-duced. AES encryption algorithm and TPM encryption are expounded. The encryption and decryption was verified in the experi-ments.关键词
