These are usually the encryption of a message digest with the senders private key. In order to verify them, the recipient uses the senders public key. They are considered good if they provide the following. Authentication Integrity Non-repudiation - Answer- Digital Signature It is a digi...

The same key is used to encrypt messages as well as decrypt messages. These algorithms are always faster but have an issue with exchanging keys. - Answer- Symmetric Cryptography Modern cryptography began when Claude Shannon publish "Communication Theory of Secrecy Systems" in 1949. He focused o...

Consists of public and private keys The public key is made public by publishing to a directory or installed on a computer. The private key is kept secret Does not involve exchanging a secret key or key exchange The public key is used to encrypt messages only the recipients private key can decryp...
