实时网络信息双重加密可逆隐藏算法仿真
|
摘要
针对当前多数可逆信息隐藏算法难以抵御选择明(密)文攻击,含密信息的视觉效果差、嵌入容量小且耗时长等问题,提出基于混沌序列的实时网络信息双重加密可逆隐藏算法。运用两种置乱方式对网络信息进行双重加密,第一次加密采用混沌序列加密算法对网络信息位置进行全局置乱。第二次加密依据另一组混沌序列对目标像素值中0bit、1bit再次置乱,以保证能够防御选择明(密)文攻击。在信息双重加密域中,采用待嵌入信息构造伪像素用于替换目标像素,实现信息的快速嵌入。根据密钥计算从密文信息中直接提取已嵌入的信息。接收方对信息解密后,提取出目标像素的每个比特数据恢复出原始网络信息,实现双重加密下的可逆信息隐藏。实验结果表明,所提算法克服了当前算法难以抵御选择明(密)文攻击的缺陷,具有信息嵌入快速高效、容量大等优势。
In this article,we present a double-encrypted reversible hiding algorithm for real-time network information based on chaotic sequence. At first,two scrambling methods were used to perform double encryption of network information. The first encryption used the encryption algorithm based on chaotic sequence to globally scramble network information position. The second encryption used another group of chaotic sequence to scramble 0 bit and 1 bit in target pixel values again,so as to ensure that the chosen plain( cipher) text attack could be defended. In the double encryption domain of information,the information to be embedded was used to construct pseudo pixel for replacing target pixel. Thus,the rapid embedding of information could be realized. According to key calculation,the embedded information was directly extracted from cipher text information. After decrypting information,the receiver extracted every bit data of target pixel to recover original network information. Finally,the reversible information hiding in double encryption was achieved. Simulation results show that the proposed algorithm overcomes the defect that the current algorithm is difficult to resist the chosen plain( cipher) text attack,which has the advantages of the fast and efficient information embedding and the large capacity.
