  • Publication number: 20160366805
    Abstract: The present invention relates to the development of a novel, morphologically and genetically distinct khusinol rich essential oil producing clone of vetiver [Vetiveria zizaniodes (L.) Nash. syn. Chrysopogon zizanioides (L.) Roberty; family Poacaeae} named ‘CIMAP-Khusinolika’. The plant of this clone is characterized by spreading type clump canopy in the initial stage, white feathery stigma and capable of producing >1% (v/w) essential oil containing 45-50% Khusinol (v/v) obtained after hydro-distillation from fresh roots harvested from 6 month old plantations. This clone has unique ISSR profiles that serve as DNA-fingerprints. The clone was obtained through recurrent selection in polycrossed population generated from the bulk of wild collection, and can be propagated through vegetative slips (3 to 6 month old stem with few roots) for commercial plantation as a short duration crop.

  • Patent number: 9401804
    Abstract: A garbled circuit is generated for a client in a leakage-resilient manner with a reduced memory requirement. The garbled circuit is used for secure function evaluation between the client and a server. The garbled circuit is generated with a reduced storage requirement by obtaining a token from the server; querying the token gate-by-gate, wherein for each gate of the garbled circuit, the token generates new wire garblings and stores them with the client using a Stream Cipher and interacts with the leakage-protected area to generate a garbled table for the gate; and receiving the garbled circuit from the token. The token comprises a leakage-protected area. The Stream Cipher is leakage-resilient and can be a symmetric-key cryptographic primitive that has a secret key as an input and generates an unbounded stream of pseudorandom bits as an output. The number of evaluations of the Stream Cipher is kept to a substantial minimum.
