Answer & Explanation:
Secure System: Computer systems are usually protected through the use of special hardware and software, policies, and practices against data corruption, destruction, interception, loss, or unauthorized access. Five essential services provided by a secure system are: Authentication; Authorization; Integrity; Privacy; and Non-repudiation. So, in general terms, a secured system provides: A reasonable security from unauthorised access and misuse; A reasonable level of reliability and operation; Reasonably performing as per the intended functions; A general adherence to accepted security norms. Public Key: In Public key encryption, two keys are used: one for encryption and another for decryption. This key is used for the encryption of the plain text to convert it into cipher text and another key (private key) is used by receiver to decrypt the cipher text to read the message. Private Key: In Private Key encryption, the same key meaning the secret key, is used for encryption and decryption. This key is symmetric because the only key is copy or share by another party to decrypt the cipher text.
