Patent number: 11748297Abstract: A hardware encryption module with reconfigurable security algorithms for randomly selecting block ciphers, stream ciphers, and their components, for internet of things (IoT) and data security applications. A corresponding system contains a hardware number generator for generating unique secrets in digital and wireless communication protocols. The system contains a cryptographically secure pseudorandom number generator for creating deterministic random sequences for the reconfigurable logic module. The system contains a multiplexing scheme to send keys and cipher texts in accordance with a wireless communication protocol. The hardware encryption module can be used to reconfigure block cipher algorithms, modes of operation, key scheduling algorithms, confusion functions, and/or round orders, based on reconfigurable logic. One type of reconfigurable logic allows stream cipher algorithms and key mixing keys to be changed at random.Type: GrantFiled: April 27, 2020Date of Patent: September 5, 2023Assignee: CSUB Auxiliary for Sponsored Programs AdministrationInventors: Reza Abdolee, Vida Vakilian

Patent number: 11165540Abstract: Space-time coded massive (STCM) and space-frequency coded (SFC) massive multiple-input multiple-output (MIMO) wireless communication systems and methods of making and using the same are disclosed. The STCM-MIMO system utilizes two massive MIMO antenna arrays that transmit data over two or more channel vectors to a user with at least one receive antenna. This configuration permits the system to use the asymptotic orthogonal qualities of massive MIMO pre-coding to eliminate the interference from other users' channel vectors and signals. The system also maintains the diversity of space-time codes to recover lost data through treating each transmitting massive MIMO array similarly to a 2×1 Alamouti space-time code. The STCM-MIMO wireless system can significantly outperform those using space-time coding techniques only. The SFC massive MIMO wireless system may be similar to the STCM-MIMO wireless system, except for the encoder block.Type: GrantFiled: January 8, 2019Date of Patent: November 2, 2021Assignee: CSUB Auxiliary for Sponsored Programs AdministrationInventors: Reza Abdolee, Jeremy J.

Vapor-Phase Deposition of Germanium Nanostructures on Substrates Using Solid-Phase Germanium Sources
Publication number: 20180251885Abstract: A method of depositing germanium on one or more substrates is disclosed. The method includes placing a source of germanium and the substrate(s) in a vapor deposition system, and heating the source of germanium in the vapor deposition system at a temperature near, at or above a melting point of elemental germanium, while flowing an inert gas over the source of germanium towards the substrate(s) for a length of time sufficient to deposit the germanium onto the substrate(s). The source of germanium is in the solid phase at ambient or room temperature. The substrate(s) may be or include one or more silicon or silicon-coated substrates, gallium nitride substrates or silicon dioxide-based substrates. The method may further include cleaning the source of germanium and the substrate(s) prior to placing the source of germanium and the substrate(s) in the vapor deposition system. The source of germanium may be elemental germanium.Type: ApplicationFiled: March 5, 2018Publication date: September 6, 2018Applicant: CSUB Auxiliary for Sponsored Programs AdministrationInventors: Yize Stephanie LI, John NGUYEN -
Publication number: 20180141037Abstract: An ion exchange column and a method of using the same are disclosed. The ion exchange column includes first interconnected chambers supporting a first portion of an ion exchange resin, second interconnected chambers supporting a second portion of the ion exchange resin, and a housing or casing enclosing the first and second interconnected chambers and the first and second ion exchange resin portions. The second chambers are physically isolated and/or separated from the first chambers. The ion exchange column is configured to cause a fluid passing through the first or second interconnected chambers to travel along a path that is longer than a height of the interconnected chambers. The present column and method improve efficiencies of fluid treatment and resin regeneration relative to a conventional dual-column design, and increase residence time between the resin and the fluid or regenerant relative to an otherwise identical single-column design.Type: ApplicationFiled: August 17, 2017Publication date: May 24, 2018Applicant: CSUB Auxiliary for Sponsored Programs AdministrationInventors: Dayanand SAINI, Usama SULTAN, Mina A.
