In the following scenario, we will compare the security services that are given by digital signatures (DS) and message authentication codes (MAC). We assume that James can read all messages send from Chan to Badrul and the other way around, too. James has no knowledge of any keys but the public one in the case of DS. State whether and how (i) DS and (ii) MAC protect against each attack. The value auth(x) is calculated with DS and MAC’s algorithm, correspondingly. i) (Message integrity) Chan sends a message x = “Transfer RM200 to Darren” in the clear and also sends auth(x) to Badrul. James intercepts the message and replaces “Darren” with “James”. Will Bob detect this?. ii) (Replay) Chan sends a message x = “Transfer RM200 to James” in the clear and also sends auth(x) to Badrul. James observes the message and signature and sends them 100 times to Badrul. Will Badrul detect this? iii) (Sender Authentication with the cheating third party) James claims that he sent some…
Hence, organizations with established IAM practices can rapidly adopt cloud services while maintaining the efficiency and efficacy of their security controls.We are aware that a digital signature serves to guarantee the validity and purity of data. a) Since checksums add up all the message's bits (or blocks), are they a viable method to build digital signature schemes? Consider a hash function, such as Sign(M)=h(M).b) If we create a signature using a hash in a trickier manner, as in Sign(k,m) = = h(k) XOR m XOR h(m), then m, will be transmitted. Would this warning be trustworthy? Describe in detail. Please refrain from using chegg or other AI tools like chat GPT.
If e = 241015, employ the low-exponent attack to determine d. please do it by hand and take care to keep many decimal places.) However, there is an important part of thisattack: if she hasn’t intercepted any ciphertexts from Alice and doesn’t already know φ(n) and is simply working with Bob’s (n,e), then how can Eve know when she has succeeded at finding d? (Note: this is cryptography, so please do it in math way)

Show that the Caesar cipher is not secure in the IND-CPA game. That is, give at least one example of messages M0 and M1 that the adversary can generate, that will provide the adversary with a non-negligible advantage in winning the IND-CPA game against the challenger. The messages M0 and M1 should be different from the ones given in lass for other cryptosystems.
Show that the El Gamal public key cryptosystem is malleable. (Hint: Showthat an adversary having the El Gamal ciphertext of a message m (but not m itself), can construct the El Gamal ciphertext of the message 2m).
