Consider the Elgamal signature scheme with Bob’s private keyK_pr=d=67 and the corresponding public key K_pub=(p,alpha,beta)=(97,23,15).Calculate the Elgamal signature (r,s) and the correspondingverification for a message from Bob to Alice with the followingmessages x and ephemeral keys k_E:
x=17 and k_E=49: r=____mod 97; s=____mod 96; and for theverification: t=____mod 97; alpha^x=____mod 97. Is the signatureverified?____Yes (Y) or No (N)
x=17 and k_E=49: r=____mod 97; s=____mod 96; and for theverification: t=____mod 97; alpha^x=____mod 97. Is the signatureverified?____Yes (Y) or No (N)
