What security goal(s) besides confidentiality can be achieved by private key cryptographic algorithms, and how? Security Goals Achieved by Private Key Cryptographic Algorithms

Safety Targets Achieved by Non-public Key Cryptographic Algorithms 

Non-public key cryptographic algorithms can be utilized to attain numerous safety targets apart from confidentiality. Authentication is a crucial safety objective the place a sender and recipient can confirm one another’s identification, which is achieved by way of the usage of digital signatures. Integrity is one other safety objective that may be achieved by way of personal key algorithms. Integrity is to make sure that knowledge will not be corrupted or tampered with throughout communication; that is achieved by way of message authentication codes (MACs) and hash features. Moreover, personal key algorithms also can present non-repudiation, that means {that a} sender can not deny having despatched a message after it has been despatched, by way of the usage of digital signatures. Lastly, personal key algorithms can be utilized for key trade and key wrapping, to securely negotiate and transport secret keys over an insecure communication channel.
