In order to detect a replay attack in a speaker recognition system, at least one feature is identified in a detected magnetic field. It is then determined whether the at least one identified feature of the detected magnetic field is indicative of playback of speech through a loudspeaker. If ...
Under replay attack to a part of network, we provide conditions on the stability of the under attack system in which, the attack cannot be detected by none of the agents. Next, a detection method is proposed which is based on using a watermarked control strategy, in which watermarking ...
A method of detecting a replay attack comprises: receiving an audio signal representing speech; identifying speech content present in at least a portion of the audio signal; obtaining information about a frequency spectrum of each portion of the audio signal for which speech content is identified; ...
In response to the issues above, this paper proposes an Efficient Parameter Transfer Learning method based on ERes2Net, named EPTLENet, to enhance the accuracy and generalization of replay attack detection. Firstly, the robustness of the algorithm is enhanced by utilizing the ERes2Net model. E...
In a method of operating a memory system, first security data and a first timestamp for preventing a replay attack are written by a host device to a first memory area which is an external memory area. A second timestamp is updated by the host device based on the first timestamp. The ...
A system that implements wireless communication with replay protection for lower power building control applications. In one example, a battery-powered device includes a counter value with each message transmitted to an always-on device. If the always-on device receive an invalid counter value, ...
