Genetic Algorithms _AND_ Cutting Wood AlgorithmA NEW PROPOSED SYMMETRIC KEY ALGORITHM FOR MODERN CRYPTOGRAPHIC
A NEW PROPOSED SYMMETRIC KEY ALGORITHM FOR MODERN CRYPTOGRAPHICijsrd.com
Ìý
This document describes a new proposed symmetric key encryption algorithm. It begins with background on cryptography and then describes the new algorithm. The algorithm encrypts text by taking the ASCII value of each character, reversing the 8-bit binary representation, dividing this by a 4-digit key, and storing the remainder in the first 3 digits and quotient in the next 5 digits to form the ciphertext. It provides an example of encrypting the character 'T' using this process. The document suggests this algorithm is easy to implement and more secure than existing algorithms due to using a reversal operation during encryption.

The document discusses the 8051 microcontroller. It describes the basic components of the 8051 including 4K bytes of internal ROM, 128 bytes of internal RAM, four 8-bit I/O ports, two 16-bit timers/counters, and one serial interface. It provides a block diagram of the 8051 and discusses important pins such as the I/O ports, PSEN, ALE, EA, RXD, TXD, and XTAL1 and XTAL2. It also gives examples of how the 8051 is used in embedded systems and describes methods for connecting an external clock source to the 8051.Idea (international data encryption algorithm)

Caesar cipher
Caesar cipherRamadhi Irawan
Ìý
The Caesar cipher is one of the earliest known substitution ciphers. It works by shifting each letter in a plaintext message by a set number of positions (the key) in the alphabet to encrypt it. For example, with a key of 3, A would be replaced by D, B by E, and so on. Decryption simply requires shifting letters in the opposite direction by the same key. While simple, the Caesar cipher has some mathematical properties and was allegedly used by Julius Caesar to communicate with his army. However, it is also easy to break through brute force by trying all 26 possible keys.

The document discusses the International Data Encryption Algorithm (IDEA). It was developed in 1990 as a replacement for the Data Encryption Standard. IDEA is a symmetric block cipher that uses a 128-bit key to encrypt 64-bit blocks of plaintext into ciphertext. The key is divided into 52 subkeys that are used in 8 rounds of encryption/decryption operations involving XOR, addition, and multiplication. IDEA was used in PGP v2.0 and can encrypt sensitive data for applications like financial services, broadcasting, and government use.Cipher techniques

The document provides an overview of cipher techniques including:
- Classical techniques like transposition ciphers, substitution ciphers including the Caesar and Playfair ciphers, and polyalphabetic ciphers like the Vigenere cipher.
- Modern techniques like stream ciphers which encrypt bits one at a time using a pseudorandom keystream, and block ciphers which encrypt blocks of text.
- It also discusses cryptanalysis techniques for analyzing ciphers and discusses how to build more secure systems using techniques like the one-time pad or combining multiple ciphers.Cryptography
CryptographyDarshini Parikh
Ìý
Cryptography is the practice and study of securing communication through techniques like encryption. It has evolved through manual, mechanical, and modern eras using computers. Cryptography aims to achieve goals like authentication, confidentiality, integrity, and non-repudiation. Common attacks include brute force, chosen plaintext, and differential power analysis. Symmetric cryptography uses a shared key while asymmetric uses public/private key pairs. Digital signatures and watermarks can authenticate documents. DRM and watermarks control digital content distribution.Cryptography

Cryptography is the science of using mathematics to encrypt and decrypt data.
Cryptography enables you to store sensitive information or transmit it across insecure networks so that it cannot be read by anyone except the intended recipient.

This document provides an overview of cryptography. It defines cryptography as the science of securing messages from attacks. It discusses basic cryptography terms like plain text, cipher text, encryption, decryption, and keys. It describes symmetric key cryptography, where the same key is used for encryption and decryption, and asymmetric key cryptography, which uses different public and private keys. It also covers traditional cipher techniques like substitution and transposition ciphers. The document concludes by listing some applications of cryptography like e-commerce, secure data, and access control.Computer Application in Business (commerce)

This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.
