Abstract
Many-to-many cryptographic systems and methods are disclosed, including numerous industry applications. Embodiments of the present invention can generate and regenerate the same symmetric key from a random token. The many-to-many cryptographic systems and methods include two or more cryptographic modules being in communication with each other and may be located at different physical locations. The cryptographic modules are configured to encrypt and/or decrypt data received from other cryptographic modules and to provide encrypted and/or decrypted data to other cryptographic modules. Each 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 are also provided.
