Abstract
Methods and systems are provided for reducing detectability of encryption keys, which may be used to encrypt messages transmitted in a network (e.g., between a base station and a mobile station, such as over the air). Random bit errors may be introduced into the messages to artificially lowering transmission quality, thus makes it harder to detect the encryption key from well-known messages. The random bit errors may be introduced by inverting one or more randomly selected bits in the encrypted message prior to transmitting.
