In а blоckchаin, Alice wаnts tо send a transactiоn 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?
