摘要： A computing device includes an array of addressable elements. Each addressable element is a hardware element that generates a substantially consistent response when interrogated. The device includes a processor coupled to the array of addressable elements and configured to communicate using a communication network. The processor receives a public key, and processes the public key to produce at least a set of addresses. Each address in the set of addresses identifies one or more hardware elements in the array of addressable elements. The processor generates a set of responses by interrogating the one or more hardware elements in the array of addressable elements identified by the set of addresses according to a set of reading instructions, appends the responses in the set of responses to generate a private key, receives an encrypted message and decrypts the encrypted message using the private key to generate an unencrypted message.

摘要： Systems and methods of authentication and encrypted communication between a server and client using independently-generated shared encryption keys are disclosed. Clients with arrays of physical-unclonable-function devices respond to server-issued challenges. The clients derive encryption keys from responses to those challenges generated by measuring PUF devices specified by the challenges. The clients send messages encrypted with the encryption keys to the server. The server independently reproduces the client-generated encryption keys using information about the PUF devices. When the keys match, the clients are authenticated. It may be desirable to inject errors into the challenge responses generated by the clients to improve security. When errors are injected, attackers cannot determine correct challenge responses except by brute force. When a sufficiently large number of errors are introduced, the server has sufficient computational power to successfully authenticate the client, but is computationally infeasible for an attacker to reverse engineer the correct responses.

摘要： Methods and compositions related to molecules and formulations comprising antibiofilm materials are provide, including new formulations of Deep Eutectic Solvents (DES) that are chemically related to choline geranate. Specifically, geranic acid (a component of choline geranate DES) is a molecule from the isoprenoid/terpene family of compounds. Other members of this family as DES components include isoprenoid acids and chemical derivatives thereof.

摘要： Disclosed herein is a computing system with the capability to execute instructions in different positional notation values. The definition of a positional notation value is given by the general formula that represent a base 10 numeral in any positional notation in the following manner: . . . d3r3+d2r2+d1r1+d0r0, where d is a coefficient, r is the base of the positional number system (i.e. r=2 for binary, or r=3 for ternary), and the exponent is the position of the digit. The computing may provide a configuration which hybridizes the instructions of multiple positional notation values in variable ratios. The computing system may dynamically switch between the multiple hybridized instructions sets. Embodiments may be applied to provide security benefits.

摘要： The present invention provides a method of detecting one or more Klebsiella species within a sample from a subject, the method comprising: subjecting DNA and/or RNA from the sample to a PCR amplification reaction using primer pairs targeting species-specific canonical single nucleotide polymorphisms (canSNPs); and analyzing amplification products resulting from the PCR amplification reaction to detect the one or more Klebsiella species. The present invention also provides a kit for detection of one or more Klebsiella species, Klebsiella clonal groups, AMR genes, and/or virulence genes, the kit comprising primer pairs targeting species-specific canSNPs, K. pneumoniae genes M1 and M2, clonal group-specific canSNPs, AMR genes, and/or virulence genes.

摘要： Systems and methods of encrypted communication between a server and client devices using keyless encryption schemes are disclosed. Client devices with arrays of physical-unclonable-function devices respond to challenges from a server. Characteristics of the arrays are stored by the server during a secure enrollment process. Subsequently, the server issues challenges to the clients. The clients derive a ciphertext according to a variable cipher scheme determined using responses to the challenges issued by the server using characteristics of portions of the arrays specified by the challenges. The server and clients may independently determine encryption and decryption procedures using characteristics of the arrays.

摘要： The present disclosure describes a novel system and method for providing a fast, inexpensive and reliable diagnostic test for indicating the presence of a biological threat. This test utilizes surface-enhanced Raman spectroscopy to interrogate a sample comprising metallic plasmonic particles suspected of contamination with the biological threat. The Raman spectrum is analyzed for specific Raman shifts that are characteristic of an interaction of the biological threat with the metallic plasmonic particles to produce a diagnostic result.
