Publication number: 20230275923Abstract: Systems and methods for detecting a Denial of Service (DoS) attack against Internet Protocol Security (IPsec) are disclosed. In one embodiment, a method comprises retrieving a first and a second Internet Security Association and Key Management Protocol (ISAKMP) packet, where the first ISAKMP packet and the second ISAKMP packet are received in immediate succession from a shared origin; storing a unique key out of a tuple wherein a value against the unique key is a time difference between the first and the second successive incoming packets; and calculating a score for each defined packet using a deep neural network, wherein a lower score value denotes an increased probability of having a DoS attack and a higher score value denotes a lower probability of a DoS attack.Type: ApplicationFiled: January 23, 2023Publication date: August 31, 2023Inventors: Ayan Chattopadhyay, Vikram Menon

Patent number: 11465482Abstract: A support device of a vehicle battery pack of a vehicle. The vehicle battery pack includes a first battery accommodating portion disposed in a first space of the vehicle and a second battery accommodating portion, where the second battery accommodating portion is greater in a vehicle-widthwise dimension than the first battery accommodating portion, where the second battery accommodating portion is connected to the first battery accommodating portion, where the second battery accommodating portion is disposed in a second space, and where the second space is below the first space in a vehicle-heightwise dimension. A frame-side bracket is disposed at a vehicle-widthwise outer surface of a web of a side rail of a ladder frame of the vehicle and projects outward in a vehicle-widthwise direction and a connecting member elastically connects the second battery accommodating portion to the frame-side bracket to suspend the vehicle battery pack to the ladder frame.Type: GrantFiled: April 26, 2019Date of Patent: October 11, 2022Assignees: Daimler AG, AVL List GmbHInventors: Vikram Menon, Markus Uhl, Roland Macherhammer, Peter Del Negro

Patent number: 11310040Abstract: Methods, systems and computer readable media are disclosed for providing a quantum cipher based on phase inversion, A shared key is established between a first party and a second party. A Hadamard transformation is applied to a message intended for a second party from the first party to produce an equal superposition state. A key phase inversion is applied to the output of the Hadamard transformation. A multiple phase inversion transformation is applied to the output of the key phase inversion to produce an encrypted quantum state with a uniform probability and relative phase distributions. The result is sent to the second party.Type: GrantFiled: March 2, 2020Date of Patent: April 19, 2022Assignee: Parallel Wireless, Inc.Inventors: Vikram Menon, Ayan Chattopadhyay
