Abstract
Methods and systems are provided for enhancing security of encrypted messages. One or more bits may be selected in an encrypted message, with the one or more bits being selected such that there is no sequence of consecutive bits in the message, having a length that is greater than or equal to a defined threshold value, that is free of bit errors. An adjustment may be applied to the encrypted message prior to transmitting the message to introduce bit errors in the message, with the adjustment being configured to affect the one or more selected bits. The adjustment may include inverting the one or more selected bits. The one or more bits may be selected and/or adjustment may be configured to reduce detectability of an encryption key used in encrypting messages.
