What are the Objectives of Cryptography? Modern cryptography follows the below objectives- Confidentiality- anyone who is out of the circle cannot understand the information between the sender and receiver. Integrity- no alteration is possible once the message is released.

Authentication- information, and sources in the cryptography system are purely authentic. Both sender and receiver can identify each other and origin or destination of the information.. Non-repudiation- none of the sender or receivers can step back of the message at a later stage. Access control- only authorized people can access the confidential data.
