Publication number: 20240098008Abstract: An anomalous behavior detector has been designed to detect novel behavioral changes of devices based on network traffic data that likely correlate to anomalous behaviors. The anomalous behavior detector uses the local outlier factor (LOF) algorithm with novelty detection. After initial semi-supervised training with a single class training dataset representing stable device behaviors, the obtained model continues learning frontiers that delimit subspaces of inlier observations with live network traffic data. Instead of traffic variables being used as features, the features that form feature vectors are similarities of network traffic variable values across time intervals. A feature vector for the anomalous behavior detector represents stability or similarity of network traffic variables that have been chosen as device identifiers and behavioral indicators.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Ke Tian, Yilin Zhao, Xiaoyi Duan, Jun Du

Patent number: 11368299Abstract: A self-encryption drive (SED) opens a communication session between the SED and a key management server. An identifier of the SED is sent to the key management server, where the identifier uniquely identifies a data structure in a database associated with the key management server and the data structure comprises a timestamp and a media encryption key (MEK). The data structure is received from the key management server, the data structure being wrapped with a shared session key associated with the communication session. The data structure is unwrapped with the shared session key and the MEK is stored only in the volatile memory of the SED based on the timestamp. Data is encrypted for storage in the non-volatile storage media of the SED based on the MEK stored only in the volatile memory of the self-encryption drive (SED). The MEK stored only in the volatile memory of the SED is erased to crypto-erase the SED.Type: GrantFiled: December 9, 2019Date of Patent: June 21, 2022Assignee: Marvell Asia Pte, Ltd.Inventors: Minda Zhang, Ke Du

Patent number: 10658003Abstract: A receiver device receives a signal via a communication channel, the signal (i) having been transmitted by a transmitter device, and (ii) corresponding to a pseudorandom bit sequence (PRBS). The receiver device correlates the received signal with a known signal to generate a correlation signal. The known signal includes the PRBS. The receiver device identifies one or more characteristics of the correlation signal, and determines one or more parameters of the communication channel using the identified one or more characteristics of the correlation signal. The receiver device i) uses the one or more parameters corresponding to the communication channel to process subsequent signals received via the communication channel, and/or ii) communicates the one or more parameters to the transmitter device to prompt the transmitter device to preprocess subsequent signals to be transmitted via the communication channel by the transmitter device.Type: GrantFiled: January 15, 2019Date of Patent: May 19, 2020Assignee: Marvell International Ltd.Inventors: Ke Du, Hongxin Song, Jun Gao
