Embodiment Construction

[0045] Below in conjunction with specific embodiment, further illustrate the present invention.

[0046] Message sender S:

[0047] Step 1: S calculates the dynamic number l required to transmit the L-bit binary ciphertext sequence m=[0, 0, 1, 1, 1, 0], the calculation formula is shown in (1-1), when L=6 , l=4.

[0048] Step 2: S calculates the forwarding order T of transmitting ciphertext m according to the arrangement rules agreed with R raw .

[0049] Specifically include the following sub-steps:

[0050] Step 2.1: S converts the ciphertext m into decimal d=14.

[0051] Step 2.2: S calculates that the transfer ciphertext m should be in T list ={t 1 , t 2 , t 3 , t 4} The number k selected in the order v in a permutation. According to the formulas (2-1) (2-2), when d=14, k=2 and v=10 are obtained, which means selecting the 10th type of permutations that can be formed by selecting 2 of the 4 dynamics.

[0052] Step 2.3: According to the arrangement rules agreed w...

Abstract

The invention belongs to the technical field of information hiding, and specifically relates to an information hiding method based on a social software user dynamic message forwarding mechanism. The method comprises the steps that a transmitter encrypts a message to obtain a binary ciphertext, selects a plurality of dynamic messages according to the length of the ciphertext, sorts the plurality ofdynamic messages according to an appointed sorting rule to obtain an initial dynamic sequence (shown in the description), and performs the replacing of the initial dynamic sequence according to a random stream generated by a shared seed to obtain an actually forwarded new dynamic sequence (shown in the description); the transmitter performs the forwarding of messages in the new dynamic sequence (shown in the description) dynamically one by one; a receiver restores the forwarded message (shown in the description) into the initial dynamic sequence (shown in the description) according to the shared random stream, restores the initial dynamic sequence (shown in the description) into a binary ciphertext according to the appointed sorting rule, and performs the decryption to obtain a message. The invention breaks through an inherent mode of information hiding, avoids the visual and statistical abnormalities caused by the embedding of information into a carrier, and can safely and effectively achieve the secret information transmission.

Description

technical field [0001] The invention belongs to the technical field of information hiding, and in particular relates to an information hiding method based on a social software user dynamic message forwarding mechanism. Background technique [0002] At present, most of the existing information hiding technologies use the information describing the objective world as the carrier. Carry out covert communication by slightly modifying the carrier data, while ensuring the perceptual fidelity and statistical fidelity of the classified information. However, in the case of new communication methods, information hiding technology should continue to develop. All kinds of information media can be used as the carrier of secret information. Only by constantly breaking through the inherent mode of information confrontation and opening up new forms of information warfare can we take the initiative in the confrontation of information security. [0003] Behavioral information hiding is the...
