A first copy of a True Random Number (TRN) pool comprising key data of truly random numbers in a pool of files may be stored on a sender and a second copy of the TRN pool is stored on a receiver. An apparent size of the TRN pool on each device is expanded using a randomizing process for selecting and re-using the key data from the files to produce transmit key data from the first copy and receive key data from the second copy.

Cryptographic systems and methods for extending apparent size of pools of truly random numbers

Systems and methods include modifying a random number pool using one or more user-identified randomization processes to produce a modified RN pool with a user-specific modification that is unknown to or otherwise separated from a RN provider. Systems and methods also include sending and receiving encrypted messages that are encrypted and decrypted using the modified RN pool.

Cryptographic systems and methods for modification of pools of random numbers

A cryptographic system includes a host device and a cryptographic device. For encryption, the host includes an application that is configured to enable a user to compose an unencrypted message on a user interface and transmit the unencrypted message. The cryptographic device is configured to receive the unencrypted message, encrypt the unencrypted message with RCPs on a non-volatile storage to create an encrypted message, and send the encrypted message to the host, which then transmits the encrypted message through a communication channel. For decryption, the host receives an encrypted message through the communication channel and sends it to the cryptographic device. The cryptographic device decrypts the encrypted message with the RCPs and sends the decrypted message back to the host, which presents the decrypted message on a display. The cryptographic device may be configured to destroy RCPs that have been used up.

Devices and methods for enabling portable secure communication using random cipher pad cryptography by enabling communications to be passed to the device from a host, encrypted and/or decrypted, and passed back to the host

Systems and methods with multiple different modes for bidirectional data transfer of messages encrypted with Random Cipher Pads (RCPs) are disclosed. A direct mode is from one single endpoint to another endpoint in a peer-to-peer fashion. A throughput mode may be configured as a communication between endpoints with a cryptographic data server (CDS) managing communications and additional encryption between the endpoints. The CDS further encrypts the messages such that there is a peer-to-peer encryption between the source endpoint and the CDS and a different peer-to-peer encryption between the CDS and destination endpoints. The throughput mode may also be configured as a broadcast communication between a sender and multiple destinations, each with its own different RCP encryption. A router-to-router mode may be thought of as a specific type of peer-to-peer transfer where the peers on each end are routers, servers, Virtual Private Network servers, and gateways rather than user endpoints.

Systems and methods include modifying a Tme Random Number (TRN) pool using one or more user-identified randomization processes to produce a modified TRN pool with a user-specific modification that is unknown to or otherwise separated from a TRN provider. Systems and methods also include sending and receiving encrypted messages that are encrypted and decrypted using the modified TRN pool.
