Patent number: 11947662Abstract: A uniform enclave interface is provided for creating and operating enclaves across multiple different types of backends and system configurations. For instance, an enclave manager may be created in an untrusted environment of a host computing device. The enclave manager may include instructions for creating one or more enclaves. An enclave may be generated in memory of the host computing device using the enclave manager. One or more enclave clients of the enclave may be generated by the enclave manager such that the enclave clients configured to provide one or more entry points into the enclave. One or more trusted application instances may be created in the enclave.Type: GrantFiled: September 22, 2022Date of Patent: April 2, 2024Assignee: Google LLCInventors: Matthew Gingell, Peter Gonda, Alexander Thomas Cope, Sergey Karamov, Keith Moyer, Uday Savagaonkar, Chong Cai

Publication number: 20230297697Abstract: A fork support is provided for duplicating an application running inside an enclave entity. In this regard, a request to duplicate an application running inside a first enclave may be received by one or more processors of a host computing device of the first enclave. A snapshot of the first enclave including the application may be generated. The snapshot may be encrypted with a snapshot key and copied to untrusted memory of the host. A second enclave may be generated. The snapshot key may be sent from the first enclave to the second enclave through a secure communication channel. The encrypted snapshot may be copied from the untrusted memory of the host into the second enclave. The encrypted snapshot may be decrypted inside the second enclave with the snapshot key.Type: ApplicationFiled: May 23, 2023Publication date: September 21, 2023Inventors: Keith Moyer, Uday Savagaonkar, Chong Cai, Matthew Gingell, Anna Sapek

Patent number: 11608592Abstract: The invention discloses a waterless fiber dyeing method using supercritical carbon dioxide fluid as a medium. Dry fibers are tightly loaded layer by layer in a porous yarn cage. After dyeing, the fibers are cleaned to remove unfixed dyes by an online way, thereby obtaining waterless dyed dry fiber products with good quality. With the supercritical carbon dioxide dyed by a dye, the invention can not only solve the problems of high energy consumption, high discharge, high pollution in the traditional dyeing process, but also obtain better dyeing effect. The invention has a simple process and convenient operation, which can effectively realize dry dyeing processing. The reaction is mild, avoiding the use of a large amount of water, heat and additives in high concentration, which has the features of being high efficiency and environmentally friendly.Type: GrantFiled: November 6, 2018Date of Patent: March 21, 2023Assignees: SOOCHOW UNIVERSITY, SHANDONG GAOMIAN GROUP CO., LTD.Inventors: Jiajie Long, Chong Cai, Chao Gao, Wei Gao

Patent number: 11560669Abstract: The present invention relates to a waterless fiber dyeing method using a mixed fluid medium, in which supercritical carbon dioxide fluid medium is mixed with steam to form a mixed fluid medium, so that the waterless fiber dyeing effect to natural fibers is improved. The method of the invention can effectively modify the hydrophobic supercritical carbon dioxide fluid medium and improve the polarity thereof, thereby increasing the solubility of polar dye under the dyeing condition and simultaneously expanding the fiber. Thus, the present invention significantly improves the dyeability and dyeing behavior of the hydrophilic fibers in supercritical carbon dioxide fluids. The invention has the advantages of simple process, convenient operation and low energy consumption, and avoids consuming a large amount of water resources and discharging pollutants in the traditional process, and has the characteristics of environmentally friendly and high efficiency.Type: GrantFiled: October 25, 2018Date of Patent: January 24, 2023Assignee: SOOCHOW UNIVERSITYInventors: Jiajie Long, Chong Cai
