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

Claim 0:
1. A method for operating a cryptographic system, comprising:
obtaining ciphertext by the cryptographic system;
performing operations by the cryptographic system to determine whether a given sequence of values exits within the ciphertext based on results from analyzing encrypted data of the ciphertext without being decrypted;
generating, by the cryptographic system, an initialization value for a cryptographic algorithm responsive to a determination that the given sequence of values exists within the ciphertext, wherein the initialization value comprises a bitrate portion including the ciphertext and a capacity portion set to zero; and
synchronizing the cryptographic system with another cryptographic system using the initialization value for the cryptographic algorithm;
wherein the cryptographic algorithm comprises an adaption of a sponge construction framework.
