Abstract
The disclosed technology provides a system and method of securely communicating data. An encryptor located at a transmitter can provide encrypted data to the transmitter. The transmitter can maintain a packet number indicating a particular packet for carrying the encrypted data and a sub-packet number indicating a position within the packet where the encrypted data is to be stored. The encryptor can produce the encrypted data using an encryptor seed generated based on the packet number and sub-packet number. A receiver can maintain a receiver packet number indicating a number of previously received packets and can compute a receiver sub-packet number. The receiver can receive a packet containing encrypted data and can decrypt the encrypted data using a decryptor seed generated based on the receiver packet number and sub-packet number.
