Cryptography is the practice and study of techniques for secure communication in the presence of adversarial behavior. Some aspects of IT security (specifically confidentiality, integrity, authentication and non-repudiation) are directly related to cryptography. Cryptographic Algorithms You can read about encryption…
Block ciphers are cryptographic algorithms that encrypt fixed-size blocks of data A cryptographic mode of operation for a block cipher describes the different ways that cryptographic algorithm may transform data to achieve sufficient complexity that offer protection against attacks. This…
Digital certificates, also known as public key certificates or identity certificate. When I explain what a digital certificate to someone without a strong IT background I like to compare it with a seal ring, like the ones used in medieval…
Trusted Platform Module (TPM, also known as ISO/IEC 11889) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. It is used to generate a password safely in a system. It…
