The RSA algorithm is a widely-used public key cryptosystem that enables secure data transmission through asymmetric encryption, relying on the computational difficulty of factoring large integers. It ensures confidentiality and authenticity by using a pair of keys: a public key for encryption and a private key for decryption, making it foundational for modern secure communications.

Asymmetric encryption is a cryptographic system that uses a pair of keys, a public key for encryption and a private key for decryption, ensuring secure communication over an insecure channel. It enables secure data transmission and authentication by allowing only the intended recipient with the private key to decrypt the message encrypted with the public key.

Confidentiality refers to the ethical and legal duty to protect private information from unauthorized access, ensuring that sensitive data is only accessible to those with the necessary permissions. It is a cornerstone of privacy rights and is crucial in fields like healthcare, law, and information technology to maintain trust and compliance with regulations.

confidentiality

Authenticity refers to the alignment of one's actions with their true self, values, and beliefs, fostering genuine connections and personal integrity. It is crucial for personal fulfillment and is often regarded as a cornerstone of ethical behavior and psychological well-being.

Encryption is the process of converting information or data into a code to prevent unauthorized access, ensuring confidentiality and data integrity. It is a fundamental technology in cybersecurity, used in various applications such as securing communications, protecting sensitive data, and verifying identities.

A private key is a cryptographic tool used in asymmetric encryption that allows the owner to decrypt messages and sign transactions, ensuring confidentiality and authenticity. It must be kept secret to maintain the security of the encryption system, as anyone who possesses the private key can impersonate the owner.
