Publication number: 20240136346Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.Type: ApplicationFiled: April 17, 2023Publication date: April 25, 2024Inventors: Chien Hung LIU, Yu-Sheng CHEN, Yi Ching ONG, Hsien Jung CHEN, Kuen-Yi CHEN, Kuo-Ching HUANG, Harry-HakLay CHUANG, Wei-Cheng WU, Yu-Jen WANG

Patent number: 8510831Abstract: The present disclosure generally pertains to systems and methods for protecting network resources from denial of service attacks. In one exemplary embodiment, a responder stores an access filter value used to determine whether an incoming message frame has been transmitted from an authorized user. In this regard, a user communication device includes logic for determining the access filter value stored at the responder and, includes the access filter value in a message frame transmitted from the computer to the responder. The responder compares the received access filter value to the stored access filter value. If such values match or otherwise correspond, the responder authenticates the message frame. However, if such values do not match or otherwise correspond, the responder discards the message frame. Thus, the responder processes authenticated message frames and discards unauthenticated message frames thereby preventing denial of service attacks from malicious users.Type: GrantFiled: January 19, 2012Date of Patent: August 13, 2013Assignee: Auburn UniversityInventors: Chwan-Hwa Wu, J.

Patent number: 8261350Abstract: A system for preventing successful denial of service attacks comprises a first communication device, a second communication device, and a network. The first and second communication devices establish a communication session via the network. Based on various information, such as a pre-shared secret, one of the communication devices determines a network access filter value and compares this value to at least one data frame in order to authenticate such data frame without committing significant computing resource and any memory space. By updating the network access filter over time, an unauthorized user who discovers the outdated network access filter values is prevented from successfully launching a denial of service attack.Type: GrantFiled: January 5, 2011Date of Patent: September 4, 2012Assignee: Auburn UniversityInventors: Chwan-Hwa Wu, J.
