The step of generating and sending a classical data stream from the source to the destination comprises encrypting the data stream with the repeated use of a once-seen pad. Observing the quantum data stream received at the destination, may indicate eavesdropping and if so, the classical data stream is modified and sent from the source to the destination, including stopping the repeated use of the once-seen pad. The same once-seen pad may be used a number of times provided no third party has seen data encrypted by the once-seen pad. | 2020-09-17 |

20200295932 | TIMESTAMP-BASED SHARED KEY GENERATION - Techniques for computer security, and more specifically timestamp-based key generation techniques, are described. Some implementations provide a table of key generation processes that is shared as a secret between a first computing system and a second computing system, both of which have synchronized clocks. Both computing systems use the same technique for selecting a key generation process from the table, such as based on a random number generator seeded with a timestamp. Since the computing systems have synchronized clocks, they both select and use the same key generation process, thereby generating the same encryption key without the need to communicate the key from one system to another. Furthermore, both computing systems may synchronize their clocks to a private time server that maintains a clock that runs faster or slower than standard time. Security is maintained by one or more of restricting access to the time server, using secret key generation processes, and/or using a secret random number generator. | 2020-09-17 |
20200295933 | Method and system for managing application security keys for user and M2M devices in a wireless communication network environment - Pre Shared Keys (“PSK”) for application and data session security are generated using application authentication secret values stored in a SIM device/card. The SIM internally uses the secret values as inputs to a security algorithm engine, but the secret values are not accessible outside of the SIM. The application authentication secret values cannot be used to authenticate the SIM, or a device that includes the SIM, to a communication network. Rather, symmetric keys and keying material are generated for use by applications outside of the standard and conventional wireless networking uses of a SIM device. Updated PSKs are generated at different network endpoints such that the PSKs are generated individually and separately at the endpoints; the ‘preshared’ keys are not actually shared. Thus, a client endpoint and a server endpoint, or an endpoint associated with the server, independently generate the same PSK without the PSK being transmitted between the endpoints. | 2020-09-17 |
