Entered 15863 Answer Preview Result 15863 incorrect The answer above is NOT correct. (1 point) There are side channel attacks on RSA that can reveal the key based on the Square and Multiply algorithm. Suppose an adversary has control of a smart card and can analyze its power usage. During operation of the card the adversary observes power usage that suggests that the Square and Multiply algorithm performed the operations: SQ, MUL, SQ, MUL, SQ, MUL, SQ, MUL, SQ, SQ, MUL, SQ, MUL, SQ, MUL, SQ, MUL, SQ, MUL, SQ, SQ, MUL, SQ, MUL What is the private exponent d (in decimal)? 15863
Study the diagram below showing the steps for Bob to send a digitally signedmessage to Alice and then answer the questions that follow: The 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 are false.These are the steps for Bob to send a digitally signed message toAlice: StepNumber Statement 1 After creating a memo, Alice generates a hash on it. 2 Bob then encrypts the hash with a public key. Thisencryption is a digital signature of the hash. 3 Bob only sends the digital signature to Alice. 4 When Alice receives them, she descripts the digitalsignature using Bob’s public key, revealing the hash. 5 Alice then hashes the memo with the different hashalgorithm Bob used and compares the result to thehash 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…
