Benefits of technology

This approach eliminates the need for key storage and sharing, enabling secure and scalable encryption and decryption processes, even in environments where human intervention is not possible, while maintaining key security and randomness.

Problems solved by technology

However, knowledge of a token will not allow someone to generate the associated key without access to each of the entropy space, the one-time seed, and the random number generator.
In other words, so long as one of the random number generator, entropy space, or one-time seed is kept secret, it is not possible to derive the key from the “token”.

Embodiment Construction

[0097]Embodiments of the present invention generally provide systems and methods that perform encryption and decryption of data. In particular, embodiments of the present invention use symmetric cryptography for encryption / decryption.

[0098]Embodiments of the present invention minimize the challenges of key management by avoiding key storage and transmission altogether. This accomplished by enabling software and hardware processes to generate and re-generate keys when needed, rather than storing and / or transmitting keys through complex schemes. These embodiments provide keys that are scalably and securely generated and re-generated when needed by the processes that use the keys.

[0099]Embodiments of the present invention can generate and regenerate the same symmetric key from a token, but knowledge of the token does not provide any advantage to an attacker to derive the symmetric key. This provides advantages over conventional cryptography systems because conventional approaches to us...

Abstract

One-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 one-to-many cryptographic systems and methods include a cryptographic module being in communication with one or more remote locations. The cryptographic module is configured to encrypt data received from the remote locations and to decrypt data for receipt by the remote locations. 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.
