Method and system for secure product delivery using cryptography

Abstract:

A method for opening a secured lockbox through a digital signature includes: storing, in a memory of a computing device in a lockbox, a public key of a cryptographic key pair; receiving, by an input device of the computing device, a digital signature from an external communication device; validating, by a processing device of the computing device, the digital signature using the public key of the cryptographic key pair; and transmitting, by a transmitter of the computing device, a signal to an electronic locking mechanism of the lockbox interfaced with the computing device; and opening, by the electronic locking mechanism of the lockbox, an electronic lock granting access to contents of the lockbox upon receipt of the signal.
