Abstract
One-to-many cryptographic systems and methods are disclosed, and a network employing the same, including numerous industry applications. The embodiments of the present invention can generate and regenerate the same symmetric key from a random token. The one-to-many cryptographic systems and methods include a central location and a cryptographic module being in communication with each other. The cryptographic module is configured to encrypt and/or decrypt data received a remote location and output encrypted and/or decrypted data. The cryptographic module includes a key generator configured to use two or more inputs to reproducibly generate the symmetric key and a cryptographic engine configured to use the symmetric key for encrypting and decrypting data. Corresponding methods, and network employing the same, are also provided.
