Explanation:A digital signature is a cryptographic mechanism used to verify the authenticity and integrity of a digital message or document. Digital signatures use asymmetric encryption algorithms, where the sender signs the message using their private key, and the receiver verifies it using the sender’s public key. Digital signatures are widely used in secure email communication,…
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: 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…
