Merkle Tree

Merkle Tree: A Merkle tree, named after Ralph Merkle, is a data structure in cryptography and computer science that consists of a hierarchical series of cryptographic hashes. Each non-leaf node is a hash of its respective children, and the hashes are organized into a binary tree. Merkle trees are used to efficiently and securely verify […]

Monolithic operating system architecture

Monolithic operating system architecture: A monolithic operating system architecture is one where the entire operating system, including the kernel, device drivers, and system services, operates in a single memory space. This traditional architecture can offer fast performance due to its direct access to system hardware, but it may be less flexible and more vulnerable to […]

Message Authentication Code (MAC)

Message Authentication Code (MAC): A short string of characters used to verify the integrity and authenticity of a message. It is generated by applying a cryptographic hash function to the message along with a secret key shared by the sender and receiver, ensuring the message’s integrity and authenticity during transmission.

Multipart Or Multipartite Viruses

Multipart Or Multipartite Viruses: A type of malware that can simultaneously infect both program files and system sectors, activating at every system startup. This dual infection approach makes it difficult to completely remove, as it can re-infect cleaned parts of the system.

Message Digest 5 (MD5)

Message Digest 5 (MD5): A widely-used cryptographic hash function that produces a 128-bit (16-byte) hash value from input data. It’s commonly used to verify data integrity. However, MD5 is considered to be broken and unsuitable for further use as it’s vulnerable to hash collisions, where different inputs produce the same output hash.

Message Digest

Message Digest: A short, fixed-length value that is generated from a longer message by a cryptographic hashing algorithm. It is used to verify the integrity of the message and to provide authentication. Examples of message digests include SHA-256 and MD5.
