    Hi,

    Following are the various applications of the digital signature. Please study them carefully, Which will clear you confusion regarding digital signature:

    A. Integrity:

    The integrity of the digital signature is that, suppose a message which sender want to sent is signed digitally , if there is any change made in the original message will invalidate the digital signature.

    B. Authentication:

    It is one of the most important application of the digital signature.
    Suppose owner of a secret key of the digital signature is addhere to a particular user then digital signature tells the sender of the original message.


    I hope this may help you..
