    Some information might be mistleading in this video.
    Digital signatures, can specifically ensure that the sender is authenticated [not the other way around as you have mentioned it in the video]. Digital signatures are used to authenticate the sender of a message or document. When a sender signs a message with their private key, it provides assurance that the message has indeed come from the claimed sender, as only the sender possessing the private key can create a valid digital signature.
    About non-repudiation, meaning that the sender cannot later deny having signed the message, as the signature is unique to the message and created using the sender's private key. [not the other way around as you have mentioned it in the video]

    Digital Signature is the opposite of RSA. For RSA, we use receiver's public key for encryption and receiver's private key for decryption. But in Digital Signature, its the opposite. We use SENDER'S private key for encryption and SENDER'S public key for decryption.

    Helpful content.. Good job... Guys she may not have given 100 percent complete info on Digital signature.. But what she explained was good enough to get basic idea.. Try watching other videos on Digital signature.. It will give broader aspect clarity... Once again thank you for creating this content.. & it has helped me

    In encryption we use public key and in decryption we use private key.
    But in this lecture you told opposite.
    Did someone else notice?

      If u use public key at sender then private at receiver or else private key at sender and public and receiver ...asymmetric alg ...any condition would work

    • @joansome951
      @joansome951 Год назад +2

      creating a digital signature is the opposite, you use the private key for encryption and public key for decryption

    how does authentication apply to the receiver if the decryption key is public?

  • @vatsparvesh
    @vatsparvesh 10 месяцев назад

    Mam u r speaking too fast😮. Some information may be corrected as authentication is at the sender end but not at the receiver end. In addition only in case of digital signature private key is used for encryption and public key for decryption.
