USF inventors created a system to establish confidential communication channels by generating time and location-limited symmetric-cryptographic keys. This system transmits confidential information only in cipher-texts, therefore ensuring the data is secure. It never stores secret keys except temporarily in volatile memory between the generation of a key and encryption/decryption, providing additional security. This novel system also has verified authenticity and integrity because receivers can always verify message sources and detect modifications of cipher-texts. This invention has great potential to secure information transmitted between multiple devices and is applicable to a wide range of industries, especially cybersecurity and hardware security modules.
