    • The motivation behind a PKI is to encourage the protected electronic exchange of data for a scope of system exercises, for example, e-business, web managing an account and secret email. It is required for exercises where straightforward passwords are an insufficient verification system and more thorough evidence is required to affirm the parties' personality included in the correspondence and to accept the data being exchanged.
