S-Box Recovery via CPA (12D Chaotic Map)
The Chosen-Plaintext Attack demonstrated full reconstruction of the substitution table for the 12D chaotic map scheme, rendering the system completely insecure.
| Attack Model | Data Complexity (Required Frames) | Computational Cost | Success Rate |
|---|---|---|---|
| CPA (12D Chaotic Map) | 256 | < 1 s | 100% |
| KPA (12D Chaotic Map) | Content Dependent | Real-time | Asymptotic |
| CCA (12D Chaotic Map) | 256 | < 1 s | 100% |
Case Study: Video Cryptosystem Breakdown
The analysis revealed that the target video cryptosystem, despite using chaotic maps, failed to adhere to fundamental cryptographic principles. Specifically, its CBC diffusion lacked key dependence and the S-boxes were static and publicly exposed. This allowed for full reconstruction of the S-box layer, leading to complete decryption of video content without the secret key, as validated by CPA, KPA, and CCA experiments.
