3.1. Study the diagram below showing the steps for Bob to send a digitally signed message to Alice and then answer the questions that follow: Q.3.1.1The statements below are the text version of the illustrated steps(step one to step five in the diagram above).Read each statement (step) and then correct all that is false.These are the steps for Bob to send a digitally signed message toAlice:StepStatementNumberAfter creating a memo, Alice generates a hash on it.Bob then encrypts the hash with a public key. Thisencryption is a digital signature of the hash.Bob only sends the digital signature to Alice.When Alice receives them, she describes the digitalsignature using Bob's public key, revealing the hash.Alice then hashes the memo with the different hashalgorithms Bob used and compares the result to the12.34hash she received from Bob.You have verified that the correct keys have been used either encrypting and/ordecrypting the digital signatures as well as the correct has algorithm is used to hashthe memo. 6 / 8187%+| E 0HashStep 1EncryptionalgorithmStep 2PlaintextalgorithmConfidential MemoHashConfidential MemoLayoffs at the Lakeviewstore will begin...Layoffs at the Lakeviewstore will begin...938276533&6%43@we DigitalQ[9}[Ox872... signatureBob (sender)Bob's private keyStep 3Transmitted toremote userEncryptionalgorithmHashAlice (receiver)algorithmConfidential MemoConfidential MemoHashLayoffs at the Lakeviewstore will begin...Layoffs at the Lakeviewstore will begin...93827653Hash 93827653Step 43&6%43@we DigitalQ[9}{Ox872... signatureBob's public keyHashes matchStep 523:04ENG2022/01/2067%21°C Mostly cloudy

Step Statement Number After creating a memo, Alice generates a hash on it. Bob then encrypts the hash with a public key. This 1 encryption is a digital signature of the hash. Bob only sends the digital signature to Alice. When Alice receives them, she describes the digital 4 signature using Bob's public key, revealing the hash. Alice then hashes the memo with the different hash algorithms Bob used and compares the result to the 2. 3,
