Alkaid: Resilience to Edit Errors in Provably Secure Steganography Via Distance-Constrained Encoding

While provably secure steganography provides strong concealment by ensuring stego carriers are indistinguishable from natural samples, such systems remain vulnerable to real-world edit errors e.g., insertions, deletions, substitutions because their decoding depends on perfect synchronization and...

Provable Secure Steganography Based on Adaptive Dynamic Sampling

The security of private communication is increasingly at risk due to widespread surveillance. Steganography, a technique for embedding secret messages within innocuous carriers, enables covert communication over monitored channels. Provably Secure Steganography PSS is state of the art for making...

From Cyber Threat to Data Shield: Constructing Provably Secure File Erasure with Repurposed Ransomware Cryptography

Ransomware has emerged as a persistent cybersecurity threat,leveraging robust encryption schemes that often remain unbroken even after public disclosure of source code. Motivated by the technical resilience of such mechanisms, this paper presents SEER Secure and Efficient Encryption-based Erasure...

DARPA Working on Provably Secure Embedded Software

DARPA is the birthplace of the network that eventually became today’s Internet, and the agency has spent the decades since it released that baby out into the world trying to find new ways defend it. That task has grown ever more complex and difficult, and now DARPA is working on a new kind of...
