Title: Sudha Krishnakumar: Innovator in Audio Data Protection
Introduction
Sudha Krishnakumar is a notable inventor based in Portland, OR (US). She has made significant contributions to the field of audio data protection, holding 2 patents that showcase her innovative approach to cryptographic technologies.
Latest Patents
Her latest patents focus on technologies for protecting audio data with trusted I/O. These technologies involve a computing device equipped with a cryptographic engine and an audio controller. A trusted software component can request an untrusted audio driver to establish an audio session with the audio controller associated with an audio codec. The trusted software component verifies that a stream identifier associated with the audio session matches a stream identifier received from the codec. The cryptographic engine is programmed with a DMA channel identifier associated with the codec, ensuring that the audio data is cryptographically protected during the session. Additionally, the audio controller locks the controller topology after establishing the audio session to prevent any re-routing of audio during a trusted audio session.
