Sir ur content is real gold. Ur channel one of most underrated channel. U should add #information and netwok security in thumbnail ....ur playlist cant be shown til i type "ins". Ur views will increase exponentially. I know u might not read this. Tnku for concept based teaching
Most IMP for tomorrow examination : All cipher techniques,active and passive attack, des, aes, diffie Hellman, rsa, application of digital signature, kerberos, DSA, public key distribution, hmac, all block cipher modes, ssh, SSL.....Share with others....
Dear AES is symmetric cipher... It provides only confidentiality... But using hash function we can achieve confidentiality, integrity and authenticity based on their different application.... But you want to apply hash function in AES.... You can do it... It is combination of public and private key cryptography...
@@sandeepsarangal3747 AES is symmetric cipher algorithm....All symmetric cipher algorithm provide confidentiality only.... Hash function provides Integrity and Authentication based on their application (Why its based on application??? If you modify some strategy then hash function also provide confidentiality but basic purpose of hash function is to serve authnetication and integrity over confidentiality.) Now as per your query, you want to apply hash function over AES.. Yes, You can apply... I hope, You are knowing about Message authentication code (MAC). it is alsmsot same to hash function...or MAC is also calle keyed hash function. Here I provide one video about MAC, which is MAC based on block cipher....In this video, I have covered MAC is applied in AES, DES, Triple DES etc... So, We also can apply hash function on all block cipher based symmetric algorithm (like AES and DES) MAC based on Block Cipher: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-usip-TmjfDQ.html Integrity, Authentication and Confidentiality: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AJTJN4wDBM8.html Hash function application (which provide integrity, authentication and confidentiality over symmetric and asymmetric cipher technique): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KexR9ylLLcQ.html I hope, all your doubts are clear. If you still have any query, you can ask me.
