Capture the Flag (CTF) is a cybersecurity competition that is used to test and develop computer security skills. It was first developed in 1996 at DEF CON, the largest cybersecurity conference in the United States which is hosted annually in Las Vegas, Nevada. [2] The conference hosts a weekend of cybersecurity competitions, including their ...
The first mention of Alice and Bob in the context of cryptography was in Rivest, Shamir, and Adleman's 1978 article "A method for obtaining digital signatures and public-key cryptosystems." [ 2 ] They wrote, "For our scenarios we suppose that A and B (also known as Alice and Bob) are two users of a public-key cryptosystem".
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
Post-Quantum Cryptography Standardization[1] is a program and competition by NIST to update their standards to include post-quantum cryptography. [2] It was announced at PQCrypto 2016. [3] 23 signature schemes and 59 encryption/ KEM schemes were submitted by the initial submission deadline at the end of 2017 [4] of which 69 total were deemed ...

Green is an Associate Professor of Computer Science at the Johns Hopkins Information Security Institute. He specializes in applied cryptography, privacy-enhanced information storage systems, anonymous cryptocurrencies, elliptic curve ...
In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991. The algorithm was intended as a replacement for the Data Encryption Standard (DES).
The Federal Information Processing Standard Publication 140-2, (FIPS PUB 140-2), [1][2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules. Initial publication was on May 25, 2001, and was last updated December 3, 2002.
