Computational Analysis of Indus Script: A Stream Cipher Decipherment Model using Harmonic Frequency Mapping

This technical note presents a novel computational approach to the undeciphered Indus Valley script. By applying a 6-digit harmonic key (674056) through a Rotational Frequency Shift (RFS) model, the research identifies consistent phonetic structures across multiple Harappan seals. Empirical results from Seal 1 (NIQHJ) and Seal 2 (JRZFX) demonstrate non-random linguistic patterns, providing a new mathematical framework for the decipherment of Harappan inscriptions.

Abstract

This technical note presents a novel computational approach to the undeciphered Indus Valley script. By applying a 6-digit harmonic key (674056) through a Rotational Frequency Shift (RFS) model, the research identifies consistent phonetic structures across multiple Harappan seals. Empirical results from Seal 1 (NIQHJ) and Seal 2 (JRZFX) demonstrate non-random linguistic patterns, providing a new mathematical framework for the decipherment of Harappan inscriptions.
