This will be the second of six cryptography primer sessions exploring the basics of modern cryptography. In this session, we’ll explore symmetric ciphers, primitives, and protocols – including AES, cipher modes, hash functions, and message authentication. Subsequent sessions (on alternating Fridays) are expected to include the following topics. Depending onContinue Reading

This will be the third of six cryptography primer sessions exploring the basics of modern cryptography. In this session, we’ll explore integral asymmetric functions including Diffie-Hellman and RSA with an emphasis on how and why they work and the properties they enjoy. Subsequent sessions (on alternating Fridays) are expected toContinue Reading

This will be the fourth of six cryptography primer sessions exploring the basics of modern cryptography. In this session, we’ll explore primality testing, elliptic curve cryptosystems, and lattice-based cryptosystems. Subsequent sessions (on alternating Fridays) are expected to include the following topics. Depending on the interests of the participants, other topicsContinue Reading

CryptArithmetic Problem. CryptArithmetic or verbal arithmetic is a class of mathematical puzzles in which the digits are replaced by letters of the alphabet or other symbols. #ArtificialIntelligence #CryptArithmeticProblem Follow me on Instagram 👉 https://www.instagram.com/ngnieredteacher/ Visit my Profile 👉 https://www.linkedin.com/in/reng99/ Support my work on Patreon 👉 https://www.patreon.com/ranjiraj source

Modern cryptography in general, and asymmetric cryptography in particular derive their efficacy from the hopeful assumption that our adversary shares our mathematical insight. And hence, if it would take us a long time to crack these ciphers, it will also take our adversary such long time. Alas, a smarter attackerContinue Reading
