# what is Asymmetric cryptosystem

COMPUTER COURSE ONLINE

This is an information system utilizing an algorithm or series of algorithms

which provide a cryptographic key pair consisting of a private key and a corresponding public

key. The keys of the pair have the properties that (1) the public key can verify a digital signature

that the private key creates, and (2) it is computationally infeasible to discover or derive the

private key from the public key. The public key can therefore be disclosed without significantly

risking disclosure of the private key. This can be used for confidentiality as well as for

authentication.
