A new academic paper in the Archive for History of Exact Sciences has detailed the discovery of advanced Sanskrit algorithms for cryptography within the 10th-century Kalyana-Kalpataru manuscript. The study demonstrates how ancient mathematicians used spherical geometry and modular arithmetic to encrypt strategic naval routes and temple coordinates into seemingly decorative verses.
The research, which utilized AI to map the metrical patterns of the Sanskrit verses to numerical matrices, found that the text employs a recursive encryption key based on planetary positions. This methodology allowed information to be hidden in plain sight, ensuring that only those with advanced knowledge of Vedic mathematics and astronomy could decipher the underlying data. The findings suggest a much earlier origin for complex data-protection systems in India.
