Authentication of data transmission devices
An intermediate data transmission device arranges for mutual authentication between itself and a remote terminal to allow data to be exchanged between the remote terminal and a server through the device. The server sends first and second key codes to the intermediate device, the key codes both being derived from a shared secret known to the server and remote terminal but not to the intermediate device. In response to a challenge from the intermediate device the remote terminal uses the shared secret to generate a duplicate of the first key code and transmits the duplicate to the intermediate device. The intermediate device compares the first key code and the duplicate of the first key code received respectively from the server and the remote terminal to verify the authenticity of the remote terminal. The intermediate device then transmits the second key code to the remote terminal, to be compared by the remote terminal with a duplicate of the second key code to verify the authenticity of the intermediate device. This process allows the intermediate device to be used without itself having the shared secret. The codes generated by the server may be encoded with a network identity of the intermediate device using the shared secret, such that the remote terminal can only respond to the same intermediate device that transmitted the codes. This prevents a “man-in-the middle” attack by another intermediate device, as without the shared secret no intermediate device can modify the codes to include a different network identity. |

Controlling word line voltages to reduce read disturb in a memory device
Apparatuses and techniques are described for reducing read disturb in a memory device by reducing the channel gradient and therefore reducing the charge injection to the memory cell. Channels of unselected NAND strings are boosted before reading memory cells in selected NAND strings. The boosting involves applying a positive voltage to source ends and drain ends of the unselected NAND strings, while drain-side select gate transistors are turned on and then off and a voltage signal of non-adjacent word lines of a selected word line, WLn, increases to a read pass voltage. A voltage signal of adjacent word lines of WLn is increased to a peak level to increase the channel conduction for faster read, where the peak level is less than the read pass voltage, decreased to a reduced level to reduce a channel gradient and therefore reduce a read disturb, then increased to the read pass voltage. |

Quanton representation for emulating quantum-like computation on classical processors
The Quanton virtual machine approximates solutions to NP-Hard problems in factorial spaces in polynomial time. The data representation and methods emulate quantum computing on classical hardware but also implement quantum computing if run on quantum hardware.

A generating function embeds the indexes into a geometric object for efficient compressed representation. A nonlinear directional probability distribution is embedded to the manifold and at the tangent space to each index point is also a linear probability distribution. Simple vector operations on the distributions correspond to quantum gate operations. The Quanton provides features of quantum computing: superpositioning, quantization and entanglement surrogates. Populations of Quantons are evolved as local evolving gate operations solving problems or as solution candidates in an Estimation of Distribution algorithm.

Token-based authentication for a proxy web scraping service
Embodiments disclose a system that allows for improved generation of web requests for scraping that, because of the nature of the requests and time and manner they are sent out, appear more organic, as in human generated, than conventional automated scraping systems. The system then manages how a client request to scrape a target website is made to the site, masking the request in a manner that makes it appear to the Web server as if the request is not generated by an automated system. In this way, by appearing more organic, Web servers may be less likely to block requests from the disclosed system or may take longer to block requests from the disclosed system. By avoiding Web servers blocking requests and extending the lifetime of IP proxies before they are blocked, embodiments can use a limited IP proxy address space more efficiently. |
