Explanation:AES is a symmetric encryption standard established by the U.S. National Institute of Standards and Technology (NIST). It is widely used for securing sensitive information due to its efficiency and robustness. AES operates on fixed block sizes of 128 bits and supports key lengths of 128, 192, and 256 bits. The algorithm performs multiple rounds…
Explanation:The RSA algorithm is one of the most widely used asymmetric encryption algorithms, named after its inventors Ron Rivest, Adi Shamir, and Leonard Adleman. It secures data transmission by generating public and private key pairs. The security of RSA is based on the mathematical difficulty of factoring large composite numbers. The algorithm supports both encryption…
Explanation:Asymmetric encryption, also known as public-key cryptography, uses two keys: a public key for encryption and a private key for decryption. These keys are mathematically related but distinct. This technique provides a secure way to exchange information without requiring prior key sharing. Anyone can encrypt data using the recipient’s public key, but only the recipient…
Explanation:Symmetric encryption is a cryptographic technique where the same key is used for both encrypting and decrypting data. This method is efficient and fast, making it suitable for large volumes of data. The sender and receiver must securely share the same secret key to use symmetric encryption. Popular symmetric encryption algorithms include AES (Advanced Encryption…
Explanation: Decryption is the process of converting encrypted data (ciphertext) back into its original readable form (plaintext) using a cryptographic key or algorithm. This process allows authorized users to access secure information. Decryption plays a critical role in secure communications, as it ensures that sensitive data transmitted over networks can be safely retrieved and understood…
Explanation: Encryption is the process of converting plaintext data into ciphertext using cryptographic algorithms. This ensures that only authorized individuals can access and decipher the information. Encryption is a cornerstone of secure communications. It is used to protect sensitive data during transmission over networks and while stored on devices. Common encryption protocols include SSL/TLS for…
Explanation: Cryptography is the science of securing information by transforming it into an unreadable format using mathematical algorithms. This ensures that only authorized individuals can access and understand the information. The primary goals of cryptography are confidentiality, integrity, authentication, and non-repudiation. Cryptographic techniques are commonly used in secure communications, online transactions, and data storage. Modern…
Explanation: Cybersecurity refers to the practice of protecting networks, systems, and data from cyber threats, including unauthorized access, cyberattacks, and data breaches. As technology advances, cybersecurity becomes increasingly essential for organizations and individuals alike. A comprehensive cybersecurity strategy involves multiple layers of protection across networks, applications, and devices. Security measures include implementing firewalls, intrusion detection…
HTML is the standard markup language used to create and design the structure of web pages. It defines the content and structure of a web document using a series of elements or tags. HTML is the foundation of every website and serves as the skeleton that other technologies (like CSS and JavaScript) build upon. Key…
