ConsenSGX: Scaling Anonymous Communications Networks with Trusted Execution Environments

Sajin Sasy, Ian Goldberg
2019 Proceedings on Privacy Enhancing Technologies  
This requirement is in place to avoid epistemic attacks, in which adversaries who know which parts of the network certain clients do and do not know about can rule in or out those clients from being responsible  ...  We analyse the requirements to actually deploy such a scheme today and conclude that it would only require a small fraction (<2.5%) of the relays to have the required hardware support; moreover, these  ...  The authors thank NSERC for grants RGPIN-03858 and STPGP-463324, and the Royal Bank of Canada for funding this research.  ...

Photosystem II Extrinsic Proteins and Their Putative Role in Abiotic Stress Tolerance in Higher Plants

Shina Sasi, Jelli Venkatesh, Rawya Daneshi, Mayank Gururani
2018 Plants  
PSII extrinsic proteins include PsbO, PsbP, PsbQ, and PsbR in higher plants, and these are required for oxygen evolution under physiological conditions.  ...  Abiotic stress remains one of the major challenges in managing and preventing crop loss.  ...  Gene coding for PsbR is not found in red algae or cyanobacteria. It was suggested that PsbR is designated on the PSII luminal side, but this has not been experimentally tested.  ...

In other words, the probability of zeros (ones for the OR operation) is 3 /4. The Strong Authentication and Strong Integrity (SASI) protocol was proposed by H. Chien in 2007 [15] .  ...  SASI protocol came as an improvement to UMAP, featuring a Rot() function that was not a triangular function, which is considered an interesting addition to arrive at the assumed secure protocol.  ...  This is because each message is based on random numbers that are changed in every successful authentication session.  ...
