Patent number: 11917083Abstract: This disclosure is directed to automated processes for attesting to trustworthiness of a host considered for connection to a data center network. The attestation process is performed in two attestation phases. In the first phase, attestation is performed on a smart network interface controller (“SNIC”) connected to an internal bus of the host using a first trusted platform module (“TPM”) of the SNIC. In the second phase, attestation is performed on the host by the SNIC using a second TPM connected to the internal bus of the host in response to a determination that the SNIC is trustworthy. The host is connected to the data center network in response to a determination by the SNIC that the host is trustworthy.Type: GrantFiled: February 7, 2022Date of Patent: February 27, 2024Assignee: VMware LLCInventors: Niu Bing, Jin He, Jinheng Xu, Li He, Juan Liu, Xiangjun Song
