Digital Archive Obfuscation via Fake Headers and Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional encryption methods are vulnerable because the existence and number of encrypted files are not hidden, making them susceptible to targeted attacks and security breaches.
Innovation Solution
A digital archive system is developed with a header section containing a mix of real and fake headers, and a body section with real and fake content, where the number of fake entries significantly exceeds the real ones, making it difficult for unauthorized users to identify and extract encrypted data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional encryption methods are used, then encryption functionality is provided, but the existence and number of encrypted files are visible, making them susceptible to targeted attacks
Solution Approach 1:
The patent creates fake headers and fake content that copy the structure and appearance of real encrypted files. These fake entries are inserted into the digital archive alongside real encrypted files, creating an indistinguishable mixture. Attackers cannot tell which entries are real and which are fake, thereby hiding the true number and existence of encrypted files from targeted attacks.
Solution Approach 2:
The patent introduces fake headers and fake content as intermediary elements between the real encrypted files and the attacker. These fake entries act as a mediator that obscures the relationship between the attacker and the real encrypted files, making it difficult to identify and target the actual encrypted data without exposing the entire archive structure.
2Reliability
If fake headers and fake content are added to hide real encrypted files, then security against targeted attacks is improved, but the size and complexity of the digital archive increases
Solution Approach 1:
The patent changes the parameters of the digital archive structure by introducing a fixed ratio between fake and real entries. By maintaining this proportional relationship, the system achieves effective obfuscation while controlling the growth of archive complexity. The fake headers and fake content are generated with specific cryptographic properties that allow for efficient creation and storage.
Solution Approach 2:
The patent applies different qualities to different parts of the digital archive. The header section contains both real and fake headers with specific structural differences, while the body contains real and fake content with varying cryptographic properties. This localized differentiation allows the system to maintain security without uniformly increasing complexity throughout the entire archive.
Data Source
AI summary
A digital archive for storing encrypted content includes a header section and a body. The header section includes real headers, wherein at least a portion of each real headers is encrypted, and fake headers, wherein each of the fake headers is filled with cryptographically random bytes, wherein the fake headers are substantially more than the real headers. The body includes real contents, wherein at least a portion of each real content is encrypted, and fake contents in the rest of the body, wherein the fake content contains additional cryptographically random bytes, wherein the amount of the fake content is substantially greater than the amount of the real contents, wherein each of the real headers refers to a corresponding real content in the body and contains decryption information for the corresponding real content.
