Did Rijndael cipher win a competition call by NIST to become the AES cryptosystem?
The Rijndael cipher did win the competition held by the National Institute of Standards and Technology (NIST) in 2000 to become the Advanced Encryption Standard (AES) cryptosystem. This competition was organized by NIST to select a new symmetric key encryption algorithm that would replace the aging Data Encryption Standard (DES) as the standard for securing

How are the standarized curves defined by NIST and are they public?
The National Institute of Standards and Technology (NIST) plays a crucial role in defining standardized curves for use in elliptic curve cryptography (ECC). These standardized curves are publicly available and widely used in various cryptographic applications. Let us delve into the process of how NIST defines these curves and discuss their public availability. NIST defines

How does AES ensure confidentiality and integrity of sensitive information during data transmission and storage?
The Advanced Encryption Standard (AES) is a widely used block cipher cryptosystem that ensures the confidentiality and integrity of sensitive information during data transmission and storage. AES achieves these goals through its secure design and implementation, which incorporates several key features and techniques. Confidentiality is achieved through AES's use of symmetric encryption, where the same
