Definition: Hybrid Cryptosystem A hybrid cryptosystem is a cryptographic system that combines the efficiency of symmetric encryption with the security advantages of asymmetric encryption. It utilizes the best features of both encryption methods to secure data transmission over potentially insecure networks. In a hybrid cryptosystem, data is encrypted with a

Definition: SSL (Secure Sockets Layer) SSL (Secure Sockets Layer) is a cryptographic protocol designed to provide secure communication over a computer network. It is the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems, preventing criminals from reading and

Definition: Off-the-Record Messaging (OTR) Off-the-Record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR ensures that messages are not only encrypted but also authenticated, meaning that the identities of the participants can be verified. Additionally, it provides forward secrecy and plausible deniability, making it a

Definition: Key Agreement Scheme A key agreement scheme is a protocol used in cryptography that allows two or more parties to agree on a shared secret key, which can then be used to encrypt and decrypt messages between them. This scheme ensures that the key is generated in such a

Definition: Transport Layer Security (TLS) Transport Layer Security (TLS) is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used for internet security, ensuring that the data transmitted between web browsers and servers remains private and integral. TLS is the successor to the Secure

Definition: Secure Shell (SSH) Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. It provides a secure channel over an insecure network in a client-server architecture, enabling users to log into another computer over a network, execute commands in a remote machine,

Definition: Broadcast Encryption Broadcast encryption is a cryptographic technique that allows the secure transmission of digital content to a group of recipients. It is designed to efficiently manage access to broadcasted data, ensuring that only authorized users can decrypt and view the content. This technology is pivotal in scenarios where

Definition: Public Key A public key is one half of a cryptographic key pair used in public key cryptography, which enables secure data exchange over insecure communication channels. It works alongside a private key to encrypt and decrypt messages, ensuring confidentiality, integrity, and authentication. Public key cryptography is fundamental to

Definition: Message Digest A message digest is a cryptographic hash function output that provides a fixed-size string of characters from an input of any size. It serves as a digital fingerprint of the input data, ensuring data integrity and security. Cryptographic hash functions are designed to be one-way functions, making

Definition: Cisco Packet Tracer Cisco Packet Tracer is a comprehensive, cross-platform network simulation software that allows users to design, build, and configure virtual networks. Developed by Cisco Systems, it serves as an educational tool for Cisco Networking Academy students and instructors, enabling the practice of networking, troubleshooting, and simulation of

Definition: Python Pygame Python Pygame is a set of Python modules designed for writing video games. It adds functionality on top of the excellent SDL library, enabling the creation of fully featured games and multimedia programs in the Python language. Pygame is highly portable and runs on nearly all platforms

Definition: MongoDB MongoDB is a NoSQL database management system known for its flexibility, scalability, and performance. It uses a document-oriented data model, which allows for varied data types and structures within a single database. Unlike traditional relational databases that use tables and rows, MongoDB stores data in JSON-like documents with
