Patent number: 11402893Abstract: Described is an apparatus comprising a first interface, a second interface, a third interface, and an interconnection fabric. The first interface may transfer a first stream of data traffic. The second interface, which may be an enhanced Serial Peripheral Interface (eSPI) interface, may transfer a second stream of data traffic and a third stream of data traffic. The third interface may transfer a fourth stream of data traffic. The interconnection fabric may couple the first interface to the second interface and may couple the second interface to the third interface. The second interface may initiate a transfer of an outbound data stream from one of the second stream of data traffic or the third stream of data traffic based on an available-space credit indicator. The second interface may receive an inbound data stream based upon the outbound data stream.Type: GrantFiled: January 7, 2019Date of Patent: August 2, 2022Assignee: Intel CorporationInventors: Zhenyu Zhu, Satheesh Chellappan, Mikal Hunsaker, Karthi R.

Patent number: 10691404Abstract: Technologies for cryptographic protection of I/O audio data include a computing device with a cryptographic engine and an audio controller. A trusted software component may request an untrusted audio driver to establish an audio session with the audio controller that is associated with an audio codec. The trusted software component may verify that a stream identifier associated with the audio session received from the audio driver matches a stream identifier received from the codec. The trusted software may program the cryptographic engine with a DMA channel identifier associated with the codec, and the audio controller may assert the channel identifier in each DMA transaction associated with the audio session. The cryptographic engine cryptographically protects audio data associated with the audio session. The audio controller may lock the controller topology after establishing the audio session, to prevent re-routing of audio during a trusted audio session. Other embodiments are described and claimed.Type: GrantFiled: March 1, 2019Date of Patent: June 23, 2020Assignee: Intel CorporationInventors: Sudha Krishnakumar, Reshma Lal, Pradeep M.
