Why in crypto(graphy) good?
Last Updated: May 07, 2019 19:22

Modern cryptography concerns itself with the following four objectives:

 

Confidentiality: the information cannot be understood by anyone for whom it was unintended

Integrity: the information cannot be altered in storage or transit between sender and intended receiver without the alteration being detected

Non-repudiation: the creator/sender of the information cannot deny at a later stage his or her intentions in the creation or transmission of the information

Authentication: the sender and receiver can confirm each other's identity and the origin/destination of the information
