Information-Theoretic Security for the Masses
This work addresses the challenge of making information-theoretic security accessible to non-experts, though it appears incremental as it builds on existing cryptographic and physical layer techniques.
The paper tackles the problem of establishing information-theoretically secure channels from memorizable secrets by combining interactive zero-knowledge protocols and weak physical layer randomness, resulting in a protocol that tolerates component failures while preserving security properties for regular users.
We combine interactive zero-knowledge protocols and weak physical layer randomness properties to construct a protocol which allows bootstrapping an IT-secure and PF-secure channel from a memorizable shared secret. The protocol also tolerates failures of its components, still preserving most of its security properties, which makes it accessible to regular users.
