Provably Secure Disambiguating Neural Linguistic Steganography
Statystyki
Recent research in provably secure neural linguistic steganography has overlooked the sender's need to detokenize stegotexts to avoid suspicion.
SyncPool method groups tokens with prefix relationships to eliminate uncertainty among ambiguous tokens.
The method ensures synchronization between sender and receiver for token selection from ambiguity pools.
Cytaty
"The sender must detokenize stegotexts to avoid raising suspicion from the eavesdropper."
"SyncPool does not change the size of the candidate pool or the distribution of tokens within the pool."
How does SyncPool ensure synchronization between sender and receiver for token selection
SyncPool ensures synchronization between the sender and receiver for token selection by utilizing a shared cryptographically secure pseudorandom number generator (CSPRNG). Both parties share an initial seed or symmetric key, allowing them to generate synchronized pseudorandom numbers. These numbers are used to select tokens from the ambiguity pools during the steganographic process. By using the same random numbers for token selection, the sender and receiver can ensure that the same token is chosen from the ambiguity pool, eliminating segmentation ambiguity and ensuring accurate message extraction.
What are the implications of segmentation ambiguity in neural linguistic steganography
Segmentation ambiguity in neural linguistic steganography refers to the uncertainty that arises when detokenizing and retokenizing text, leading to potential decoding errors. This ambiguity occurs when multiple tokens can represent the same text, causing confusion during the extraction of the embedded message. If the sender and receiver do not synchronize their token selection processes, decoding errors can occur, impacting the reliability and security of the steganographic communication. SyncPool addresses this issue by grouping ambiguous tokens and synchronizing the sampling process, ensuring accurate message extraction.
How can the SyncPool method be applied to other forms of steganography beyond linguistic steganography
The SyncPool method can be applied to other forms of steganography beyond linguistic steganography by adapting the concept of ambiguity pools and synchronized sampling to different data types and embedding techniques. For image steganography, for example, ambiguity pools could be created based on pixel values or color channels, and synchronized sampling could ensure that the same pixel or color is selected for embedding and extraction. Similarly, in audio steganography, ambiguity pools could be formed based on audio segments or frequencies, with synchronized sampling ensuring consistent message extraction. By incorporating the principles of SyncPool into various steganographic methods, the reliability and security of the communication can be enhanced across different data formats.
