Diffie-Hellman (DH or D-H)
Diffie-Hellman (DH or D-H): A cryptographic protocol enabling secure key exchange over a public channel, allowing two parties to establish a shared secret key without directly sharing private information. It is foundational for secure communications, underpinning many encryption and secure communication technologies.
Distributed Network Protocol (DNP3)
Distributed Network Protocol (DNP3): Distributed Network Protocol 3 (DNP3) is an open, standards-based protocol used primarily for communications between various types of data acquisition and control equipment. It is widely used in utilities and industrial automation systems to support the management of smart grids, SCADA systems, and other telemetry and control applications. DNP3 facilitates reliable […]
Diffusion
Diffusion: In cryptography, diffusion refers to the technique of dispersing the influence of a plaintext character across many ciphertext characters. This ensures that changing one character in the plaintext results in multiple changes in the ciphertext, making it more resistant to statistical analysis and enhancing security.
Distributed System
Distributed System: A networked computational model in which software and data components residing on multiple machines work in harmony to accomplish tasks or processes. This model optimizes the use of resources, enhances reliability and scalability, and enables the simultaneous processing of tasks, leading to faster completion times and efficient system utilization.
Digital Code Signing
Digital Code Signing: The process of using a digital certificate to sign a piece of software or code. This signature verifies the identity of the software author and assures the recipient that the code has not been altered or corrupted since it was signed. This helps protect users from installing malicious software disguised as legitimate […]
DNSSEC
DNSSEC: A security extension for the DNS protocol that uses digital signatures to ensure the authenticity of DNS data and protect it from tampering and spoofing, thereby preventing attacks such as DNS poisoning.
