We take an important step forward in making Oblivious RAM (O-RAM) practical. We pro-pose an O-RAM construction achieving an amortized overhead of 20 ∼ 35X (for an O-RAMroughly 1 terabyte in size), about 63 times faster than the best existing scheme. On the theoreticfront, we propose a fundamentally novel technique for constructing Oblivious RAMs: specifi-cally, we partition a bi...

For 6 years adult, non-synchronized Hampshire ewes (n=2,5,8,8,9 and 12) and rams (n=6,10,12,11,11 and 9) were maintained separately and released to contiguous pastures having in common a woven-wire fence about 80m long and 1.1m high. Natural estrous cycles were monitored daily by observations of ram-seeking behavior as defined as a ewe being persistent in staying at the common fence with attent...

We define the concept of and present provably secure constructions for Anonymous RAM (AnonRAM), a novel multi-user storage primitive that offers strong privacy and integrity guarantees. AnonRAM combines privacy features of anonymous communication and oblivious RAM (ORAM) schemes, allowing it to protect, simultaneously, the privacy of content, access patterns and user’s identity, from curious se...

A study was conducted to investigate the effect of season on, and to estimate heritabilities of, and genetic correlations among, semen and spermatozoa characteristics and the relationship of these characteristics with measures of testicular or scrotal size in 6-, 9- and 12-month old ram lambs of Menz and Horro sheep breeds indigenous to Ethiopian highlands. A total of 278 ram lambs with substan...

This study was conducted to evaluate maternal breed effects, direct breed effects, and individual heterosis on subsequent steer performance, carcass, and feed efficiency traits. This was a consecutive 2-yr trial using 158 steers. The same dam breeds, Angus (AN) and purebred Simmental (SM), were used both years. Also, the same AN and SM sires (n=11) were used both years. Steers were AN, SM, or A...

The study evaluated the effect of two animal protein-free extenders on ram semen cryopreservation tropical hair breeds. ejaculates were collected from 8 rams (4 Blackbelly and 4 Pelibuey), which mixed (pooled) by breed, diluted cryopreserved in three different extenders: Animal protein [Tris egg yolk (Triladyl®)], AndroMed® (lecithin soy bean) OPTIXcell® (liposome). Sperm analyses total (TM) pr...

Oblivious RAM (O-RAM) is a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. This paper proposes novel O-RAM constructions that achieves poly-logarithmic worst-case cost, while consuming constant client-side storage. Our techniques for constructing Oblivious RAM are fundamentally different from previous approache...

Garbled RAM, introduced by Lu and Ostrovsky (Eurocrypt 2013), provides a novel method to garble RAM (Random Access Machine) programs directly. It can be seen as a RAM analogue of Yao’s garbled circuits such that, the size of the garbled program and the time it takes to create and evaluate it, is proportional only to the running time of the RAM program, avoiding the inefficient process of first ...
