upon receipt of the object from the supply chain the destination point can extract the portion or portions of the encryption key and the encrypted message from the object packaging surrounding the object and or labels affixed to the object or packaging obtain the remaining portion of the encryption key directly from the source point reassemble the encryption key and decrypt the encrypted message to produce a computed message the destination point can then obtain the original message from the source point and compare the original message to the decrypted message in order to determine whether or not the shipment is authentic application_number US 10506505 A description the present invention is related to securing shipment of objects through supply chains in described embodiments of the present invention an encryption based system is employed to allow the recipient of a shipment to authenticate the shipment based on information included or incorporated within the object shipped or incorporated within or affixed to various nested levels of packaging surrounding the object first basic cryptography is reviewed in the following subsection then in a subsequent subsection embodiments of the present invention are discussed certain embodiments of the present invention employ cryptographic methodologies in order to secure shipment of objects through supply chains in this subsection an overview of a number of basic cryptographic methods is provided fig3 illustrates a basic principle underlying cryptographic methodologies cryptography is designed to transform plain text information into encoded information that cannot be easily decoded by unauthorized entities for example fig3 shows a plain text.
