In a blockchain, Alice wants to send a transaction to Bob. She signs the transaction with her private key, and Bob wants to verify the authenticity of the transaction. Alice’s transaction has the following form: Transaction Data: TT Alice’s private key: kAk_A​ Alice’s public key: pAp_A​ The transaction signature is given as σA=Signk(T)  where Signk(T)\text{Sign}_k(T) is the digital signature of the transaction data TT, signed using Alice’s private key kAk_A. To verify the authenticity, Bob computes the following equation:  Verifyp(T,σA)=TrueifVerifyp(T,σA)=Decryptp(σA)==H(T) \text{Verify}_p(T, \sigma_A) = \text{True} \quad \text{if} \quad \text{Verify}_p(T, \sigma_A) = \text{Decrypt}_p(\sigma_A) == H(T)Where: Verifyp(T,σA)\text{Verify}_p(T, \sigma_A) is the verification function using Alice’s public key pAp_A. H(T)H(T)is the hash of the transaction TT. What conditions must hold for Bob to accept the transaction as valid?

Hassol argued that you should you use the word “anthropogenic” to describe climate change because it sounds more authoritative than “human-caused.”

Bob wants to store a piece of data DDD on the blockchain, ensuring its integrity. To do so, he generates a hash H(D)H(D), which is the cryptographic hash of the data DD. The hash function HH satisfies the following properties: Preimage Resistance: Given a hash hh, it is computationally infeasible to find DD such that H(D)=hH(D) = h. Collision Resistance: It is computationally infeasible to find two different data sets D1≠D2D_1 \neq D_2​ such that H(D1)=H(D2)H(D_1) = H(D_2). Now, consider that Bob stores (D,H(D))(D, H(D)) on the blockchain, and later, Alice retrieves this data. Alice wants to verify the integrity of DD. The integrity check is given by: Integrity Check =True if H(D)==H(D′)Where D′D’ is the retrieved data and H(D′)H(D’) is the hash of the retrieved data. What must Alice check to ensure the integrity of the data?

A disheveled, severely depressed patient with psychomotor retardation has not showered for several days. The nurse should:

Given a message “Hello, World!” and a hash function H, if H (“Hello, World!”) produces the hash value “5eb63bbbe01eeed0934c4f570a7d8d27”, which property of the hash function is demonstrated?

During an assessment, the patient tells the nurse that she is constantly worrying about her room and that she checks to be sure all of her things are neatly put away and in order every hour or two throughout the day. The nurse identifies this behavior as an indication of:
