“…A widely-available, high-throughput, low-latency TRNG will enable all previously mentioned applications that rely on TRNGs, including improved security and privacy in most systems that are known to be vulnerable to attacks [90,115,162], as well as enable research that we may not anticipate at the moment. One such direction is using a one-time pad (i.e., a private key used to encode and decode only a single message) with quantum key distribution, which requires at least 4Gb/s of true random number generation throughput [34,94,154]. Many high-throughput TRNGs have been recently proposed [12,15,31,42,48,80,82,101,110,147,154,159,162,163], and the availability of these high-throughput TRNGs can enable a wide range of new applications with improved security and privacy.…”

We propose a new DRAM-based true random number generator (TRNG) that leverages DRAM cells as an entropy source.The key idea is to intentionally violate the DRAM access timing parameters and use the resulting errors as the source of randomness. Our technique speci cally decreases the DRAM row activation latency (timing parameter t RCD ) below manufacturerrecommended speci cations, to induce read errors, or activation failures, that exhibit true random behavior. We then aggregate the resulting data from multiple cells to obtain a TRNG capable of providing a high throughput of random numbers at low latency.To demonstrate that our TRNG design is viable using commodity DRAM chips, we rigorously characterize the behavior of activation failures in 282 state-of-the-art LPDDR4 devices from three major DRAM manufacturers. We verify our observations using four additional DDR3 DRAM devices from the same manufacturers. Our results show that many cells in each device produce random data that remains robust over both time and temperature variation. We use our observations to develop D-RaNGe, a methodology for extracting true random numbers from commodity DRAM devices with high throughput and low latency by deliberately violating the read access timing parameters. We evaluate the quality of our TRNG using the commonly-used NIST statistical test suite for randomness and nd that D-RaNGe: 1) successfully passes each test, and 2) generates true random numbers with over two orders of magnitude higher throughput than the previous highest-throughput DRAM-based TRNG.

“…When the quick response is needed, a positive short pulse can be applied to the source-drain electrode, the electron will recombine the trapped hole and reset the device, this will make rapid time response. The responsivity is as high as 4.8 × 10 6 A/W at 50 K, with 4.3 × 10 −14 W laser source power at 808 nm. Additionally, at room temperature, the detector's responsivity is 461A/W with 8.25 × 10 −12 W source power.…”

“…The MC simulations showed that the performance of the device could be optimized by reducing the horizontal trench width. The fabricated QD-ASN-FET-PD exhibits responsivity as high as 4.8 × 10 6 A/W at 50 K at 808 nm, which makes the weak light detection possible. This research provides a new method for optimizing a QDFET with high photocurrent response.…”

We present a novel device for weak light detection based on self-gated nanowire field effect structure with embedded quantum dots beside the nanowire current channel. The quantum dot with high localization energy will make the device work at high detecting temperature and the nano-channel structure will provide high photocurrent gain. Simulation has been done to optimize the structure, explain the working principle and electrical properties of the devices. The nonlinear current-voltage characteristics have been demonstrated at different temperatures. The responsivity of the device is proven to be more than 4.8 × 106A/W at 50 K.

“…New protocols have recently been proposed that lift the requirement of operating a multiport and it is highly likely that future QDS test-beds will employ variations on these protocols. 35 Although 850 nm wavelength light has been successfully demonstrated in telecommunications optical fiber QKD systems [20][21][22][23]36,37 , suggesting that it could also be used successfully for QDS in the same type of fiber, true low loss long haul operation requires a system with a source wavelength that is around 1.3 μm or 1.55 μm.…”

Classical digital signatures are commonly used in e-mail, electronic financial transactions and other forms of electronic communications to ensure that messages have not been tampered with in transit, and that messages are transferrable. The security of commonly used classical digital signature schemes relies on the computational difficulty of inverting certain mathematical functions. However, at present, there are no such one-way functions which have been proven to be hard to invert. With enough computational resources certain implementations of classical public key cryptosystems can be, and have been, broken with current technology. It is nevertheless possible to construct information-theoretically secure signature schemes, including quantum digital signature schemes. Quantum signature schemes can be made informationtheoretically secure based on the laws of quantum mechanics, while classical comparable protocols require additional resources such as secret communication and a trusted authority.Early demonstrations of quantum digital signatures required quantum memory, rendering them impractical at present. Our present implementation is based on a protocol that does not require quantum memory. It also uses the new technique of unambiguous quantum state elimination, Here we report experimental results for a test-bed system, recorded with a variety of different operating parameters, along with a discussion of aspects of the system security.
