Distributed Denial-of-Service (DDoS) Attack
Distributed Denial-of-Service (DDoS) Attack: A malicious attempt to disrupt normal traffic to a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of internet traffic. DDoS attacks are performed using multiple compromised computer systems as sources of attack traffic, which could include computers and other networked resources such […]
Differential Cryptanalysis
Differential Cryptanalysis: A method of analyzing and potentially breaking cryptographic systems, especially symmetric key schemes. It involves the study of how differences in an input can affect the resultant difference in the output. By observing these differences, an attacker might be able to infer the secret key used for encryption, thereby decrypting the contents without […]
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.
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.
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.
Default Password
Default Password: A pre-set password provided by the manufacturer of a hardware device or software application that is intended to be used during the initial setup process. Default passwords are often common and well-known, which can pose a significant security risk if not changed after installation or setup. It is considered a critical security practice […]
