Patent ID: 11870884
Assignee: HARRIS GLOBAL COMMUNICATIONS, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A communication device, comprising:
a transceiver configured to transmit and receive signals including ciphertext;
a cryptographic circuit configured to encrypt and decrypt information in accordance with a cryptographic algorithm; and
a synchronization circuit configured to synchronize the cryptographic algorithm with a cryptographic algorithm of another communication device based on a detection of a pseudo-random event during an on-going communication session;
wherein the pseudo-random event is detected via an analysis of the ciphertext; and
wherein the cryptographic algorithm is initialized using an initialization value generated response to a detection of the pseudo-random event, the initialization value comprising a bitrate portion including the ciphertext and a capacity portion set to zero;
wherein the cryptographic algorithm comprises an adaption of a sponge construction framework.
