Understanding Digital Signatures in Cloud Computing 🔐

10.3. Digital Signature https://youtu.be/2deexiReCac The #digital #signature #mechanism is a means of providing data #authenticity and #integrity through #authentication and non-repudiation. A #message is assigned a digital signature prior to #transmission, which is then rendered invalid if the message experiences any subsequent, #unauthorized #modifications. A digital signature provides #evidence that the message #received is the same as the one created by its #rightful #sender. . Both #hashing and #asymmetrical #encryption are involved in the creation of a digital signature, which essentially exists as a message digest that was encrypted by a #private #key and appended to the original message. The recipient verifies the signature #validity and uses the corresponding #publickey to #decrypt the digital signature, which produces the message digest. The hashing mechanism can also be applied to the #original message to produce this message digest. #Identical results from the two different processes indicate that the message maintained its integrity. The digital signature mechanism helps #mitigate the #malicious intermediary, #insufficient authorization, and #overlapping trust boundaries security threats . Cloud Service Consumer B sends a message that was digitally signed but was altered by trusted #attacker Cloud Service #Consumer A. Virtual Server B is configured to verify digital signatures before processing incoming messages even if they are within its trust boundary. The message is revealed as illegitimate due to its invalid digital signature, and is therefore #rejected by #VirtualServer B. #Cloud #computing #concept(chapter 10) #Book Link :- https://drive.google.com/file/d/1ELVZhFR9lbrsru0sQD696m7TR8qjHXmY/view?usp=sharing CLOUDCOMPUTING #THEORY PLAYLIST https://youtube.com/playlist?list=PLHeKsaIQNmloJLQLvgFV0rUK6B011ANL2 CLOUD COMPUTING #PRACTICAL #PLAYLIST. https://youtube.com/playlist?list=PLHeKsaIQNmlrtj6yxcuD7hQ7mvo3MY1Fq #Subscribe the Channel Link :- #bansodetechsolution #ajupgrading https://www.youtube.com/c/AjUpgradingBANSODETECHSOLUTION?sub_confirmation=1 IF any Query or Doubt DM on #Instagram :- #bansode_ajay_2102 https://www.instagram.com/bansode_ajay_2102?r=nametag @bansode_tech_solution Link for slides, code samples and text version of the video #blogger https://bansodetechsolution.blogspot.com/2022/08/105-identity-and-access-management-iam.html
