Patent number: 11860993Abstract: A method of operating an electronic device includes generating scramble control codes. The scramble codes are generated by generating a random number, shifting the random number to produce a shifted random number, generating control signals by selecting different subsets of the shifted random number, and generating scramble control words by selecting different subsets of the random number based upon the control signals. The method further includes receiving a password comprised of sub-words and scrambling those sub-words according to the scramble control codes, retrieving a verification word comprised of sub-words and scrambling those sub-words according to the scramble control codes, and comparing the scrambled sub-words of the password to the scrambled sub-words of the verification word to thereby authenticate an external device that provided the password.Type: GrantFiled: August 6, 2021Date of Patent: January 2, 2024Assignee: STMicroelectronics International N.V.Inventor: Dhulipalla Phaneendra Kumar

Patent number: 11647949Abstract: Embodiments herein provide a method for stereo-visual localization of an object by a stereo-visual localization apparatus. The method includes generating, by a stereo-visual localization apparatus, a stereo-visual interface displaying the first stereo image of the object and the first stereo image of the subject in a first portion and the second stereo image of the object and the second stereo image of the subject in a second portion. Further, the method includes detecting, by the stereo-visual localization apparatus, a movement of the subject to align the subject in the field of view with the object. Furthermore, the method includes visually aligning, by the stereo-visual localization apparatus, the subject with the object based on the movement by simultaneously changing apparent position of the first and the second stereo images of the subject in each of the first portion and the second portion in the stereo-visual interface.Type: GrantFiled: June 7, 2018Date of Patent: May 16, 2023Assignee: Samsung Electronics Co., Ltd.Inventors: Shankar Mosur Venkatesan, Phaneendra Kumar Yalavarthy, Trivikram Annamalai

Patent number: 11281795Abstract: A system includes a random number generator generating a random number in response to an event. Control logic generates hierarchical part alignment selectors from the random number. For each secure data block to be stored in volatile storage, a physical address of a first logical address for that secure data block is set based upon the hierarchical part alignment selectors. For each data word within that secure data block, a physical address of a first logical address for that data word is set based upon the hierarchical part alignment selectors. For each data byte within that data word, a physical address of a first logical address for that data byte is set based upon the hierarchical part alignment selectors. A physical address of a logical address for a first data bit within that data byte is set based upon the hierarchical part alignment selectors.Type: GrantFiled: December 24, 2019Date of Patent: March 22, 2022Assignee: STMicroelectronics International N.V.Inventor: Dhulipalla Phaneendra Kumar

Patent number: 11227046Abstract: Disclosed herein is a method of performing a password challenge in an embedded system. The method includes receiving a password, scrambling the sub-words of the password pursuant to scramble control codes, retrieving a verification word, scrambling the sub-words of the verification word pursuant to the scramble control codes, and comparing the scrambled sub-words of the password to the scrambled sub-words of the verification word. Access to a secure resource is granted if the scrambled sub-words of the password match the scrambled sub-words of the verification word. The scramble control codes cause random reordering of the sub-words of the password and sub-words of the verification word in a same fashion, and insertion of random delays between the comparison of different sub-words of the password to corresponding sub-words of the verification word.Type: GrantFiled: December 24, 2019Date of Patent: January 18, 2022Assignee: STMicroelectronics International N.V.Inventor: Dhulipalla Phaneendra Kumar

Patent number: 10951703Abstract: Techniques of peer-to-peer email synchronization are disclosed herein. In one embodiment, a technique includes transmitting, from a first client device to an email server, a synchronization request to synchronize an email between the email server and the first client device. In response, the first client device receives a reply containing data representing a replicate identification of email content of the email and identification of a second client device at which a copy of the email content is present. Upon receiving the reply, the first client device can establish a peer-to-peer communications channel with the second client device, download a copy of the email content of the email from the second client device instead of the email server, and surface the downloaded email content in an email client on the first client device to a user.Type: GrantFiled: October 15, 2019Date of Patent: March 16, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Kushal Ghosh, Nikhil Kalu, Phaneendra Kumar Dwadasi
