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 a plurality of cryptographic modules in communication over a network. A cryptographic module is configured to encrypt data to be sent to other cryptographic modules and to decrypt data received from other cryptographic modules. 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 are also provided.
