Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Base Excision Repair

26.1K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Lewis Acids and Bases

48.2K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Weak Base Solutions

24.9K
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Ions as Acids and Bases

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

Area of Science:

  • * Computer Engineering
  • * Cybersecurity
  • * Wireless Communication

Background:

  • * Ultra High Frequency Radio Frequency Identification (UHF RFID) is crucial for the Internet of Things, enabling batteryless wireless nodes.
  • * Security is paramount for UHF RFID due to its transmission range and data sensitivity, leading to ISO-29167 cryptographic standards.
  • * Current UHF RFID readers lack crypto capabilities, necessitating flexible solutions like Software Defined Radios (SDRs).

Purpose of the Study:

  • * To implement and evaluate the ISO 29167-19 standardized RAMON decryption on an SDR platform.
  • * To address the performance limitations of initial LabVIEW-based implementations for cryptographic operations.
  • * To develop a viable prototyping platform for secure UHF RFID systems.

Main Methods:

  • * Initial implementation of RAMON decryption using LabVIEW for SDR control.
  • * Performance bottleneck identification due to LabVIEW's limitations with large number computations.
  • * Optimized approach: LabVIEW for protocol/transceiver control, with Java handling the computationally intensive decryption.

Main Results:

  • * The initial LabVIEW-only decryption took 51 seconds, rendering it impractical.
  • * The optimized approach, offloading decryption to Java, reduced processing time to approximately 2.2 ms.
  • * This represents a speed improvement of over 23,000 times, meeting practical timing requirements.

Conclusions:

  • * The optimized Java-based decryption on SDR is suitable for realistic UHF RFID prototyping and application scenarios.
  • * This method facilitates the development and testing of new cryptographic functionalities in UHF RFID systems.
  • * It represents a significant step towards fully compliant, adaptable, crypto-enabled UHF RFID interrogators.
