Location-Based Cryptographic Authentication: A Coordinate-as-Key Protocol for Physical Presence Verification

Puntos clave

• This research aims to introduce a protocol that utilizes geographic coordinates as cryptographic keys for authentication.
• Developed the Coordinate-as-Key (CaK) protocol that binds keys to physical locations
• Defined and conceptualized Presence-Bound Cryptography (PBC)
• Conceived the protocol's principles at a specific GPS coordinate in Japan.
• The key is unique to physical locations and cannot be replicated remotely
• Establishes a new authentication method distinct from traditional password systems
• Introduces the concept of tying cryptographic security to geographical existence rather than knowledge.
