摘要： The invention disclosed techniques for enhancing a security level of a communication signal, comprising the following steps:
• receiving a message m as input data;
• adding artificial noise of a level NArt according to a function f-1(m) to the message m so that
o after a transmission of the communication signal x over a communication channel T with a noise level NT to a receiver that transforms the communication signal x to the communication signal y, the message remains readable to the receiver;
o after a transmission of the communication signal x over a communication channel E with a noise level NE to an eavesdropper that transforms the communication signal x to the communication signal z, the message gets unreadable to the eavesdropper.

摘要： The invention disclosed a Security module SMs of a sending unit for providing a security level in data communication, wherein the security module SMs is configured to receive a message m as input data and configured to transform it to a communication signal x comprising the message m, wherein the security module SMs comprises an encryption-based security module SMS, enc and an PLS-based security module SMS, PLS, wherein
• the encryption-based security module SMS, enc encrypts the message by using a key, and
• the PLS-based security module SMS, PLS comprises an artificial-noise-generating component configured to add artificial noise of a level NArt according to a function f-1 to the message so that
o after a transmission of the communication signal x over a communication channel T with a noise level NT to a receiver that transforms the communication signal x to the communication signal y, the message remains readable to the receiver.
