摘要
针对现有视频监控的信息安全问题,采用ARM Cortex-A8,USB摄像头,AES加密模块,以及可信计算芯片(TPM)设计了视频监控安全模块。用AES对视频采集端采集的视频数据进行加密,通过网络将密文传输到服务端。对于AES密钥的传输安全问题,以可信计算为基础,通过TPM的绑定功能进行非对称加密,采用对称密码和非对称密码配合使用的混合加密方案,实现对称密钥加密数据,非对称密钥加密对称密钥的加密功能。简要介绍了安全视频监控的组成,对AES加密算法和TPM加密做了阐述,最后通过实验验证加密解密。
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 encryption function of symmetric key encrypted asymmetric key.The composition of security video surveillance is briefly introduced.AES encryption algorithm and TPM encryption are expounded.The encryption and decryption was verified in the experiments.
