Abstract:

The visually meaningful image encryption (VMIE) scheme has attracted the attention from researchers due to its ability to conceal encrypted images in plaintext images without raising suspicion from attackers. In order to enhance the performance of the system in terms of capacity and security, many VMIE schemes based on compressed sensing have been proposed. However, it remains difficult to solve the key management problem effectively in these schemes. Therefore, a VMIE scheme based on twin physically unclonable functions and compressed sensing was proposed. First, the complete key seed was embedded in the carrier image to achieve public network key exchange while avoiding additional communication consumption. With the key seed being encrypted and encoded, both security and robustness were guaranteed. Subsequently, the key seed was iteratively extended using a hash algorithm to generate the key stream. The experimental results demonstrated that the scheme can achieve the balance of security, embedding capacity, and robustness.

Key words: visually meaningful image encryption, compressive sensing, physical unclonable function, hash chain
