摘要:
无线通信技术的飞速发展推动移动终端间的数据业务日益增多,如何解决数据的传输安全显得尤其重要。 为解决数据传输的安全问题,提出一种基于音频载体的特定信息隐藏算法。 首先对特定信息进行随机密钥混沌加密和 CRC 编码处理来提高传输的安全性,之后对音频载体进行离散小波变换,取低频分量进行特定的分段处理,然后对每段数据进行SVD 分解得到奇异值,对所有奇异值进行大小排序,将加密后的特定信息通过奇偶量化方法嵌入到较大的奇异值中。 通信接收方收到音频数据后,通过对音频数据进行离散小波变换与 SVD 分解提取出嵌入的信息,之后进行 CRC 解码校验和混沌解密即可得到特定信息。 实验结果验证了该隐藏算法在嵌入信息后具有不错的透明性,并且可以较好地抵抗常规攻击。
Abstract:
The rapid development of wireless communication technology has promoted the increasing number of data services for mobile terminals,so how to solve the problem of data transmission security is particularly important. An information hiding algorithm based on audio carrier is proposed. Firstly, random key chaotic encryption and CRC encoding are performed for specific information to improve transmission security. Secondly, discrete wave-let transform is carried out on the audio carrier, and the low-frequency component is selected for specific segmentation processing. Then SVD deco-mposition is carried out on each data segment to obtain the singular value,and the size of all singular values is sorted. The encrypted specific infor-mation is embedded into the large singular value through the parity quantization method. After the communication receiver receives the audio data, the embedded information is extracted by discrete wavelet transform and SVD decomposition of the audio data,and then the specific information can be obtained by CRC decoding and chaos decryption. The experiment verifies that the proposed hidden algorithm has excellent transparency after embedding information and can resist normal attacks.
