Security Services for Protocols We want to explore security services of secrecy, integrity, authenticity, and non-repudiation can be provided by the combination of different cryptographic primitives. The original message m is being processed as described in the short protocols below. Then it is sent as data stream y from one party to another (e.g., from Alice to Bob). To realize the protocols, a hash function H(x), a message authentication code MAC(x), a digital signature Sign(x), a stream cipher EncS(x) and a block cipher EncB (x) are used. State which security services are provided by which protocol. Also give a brief explanation why security service is provided or not. When checking integrity, differentiate between random changes occurring during transmission via a noisy channel and deliberate changes introduced by an adversary. (a) y=[H(m),m] (b) y=[MAC(m),m] (c) y=[EncS(H(m)),m] (d) y=EncB(m,H(m)) (e) y=EncS(m,Sign(ml)), with ml being the last block of a message m.

Answers

Answer 1

Protocol (a) offers data integrity through the application of H(m) hash function, yet it does not deliver confidentiality, genuineness, and non-denial protection.

What is the job of Protocol B?

(b) Although the Protocol (b) ensures message authenticity and integrity through the use of a message authentication code (MAC), it falls short in providing secrecy and non-repudiation.

The (c) protocol offers confidentiality via EncS and ensures the trustworthiness and uniqueness of data through H(m). However, non-repudiation is still missing.

Protocol (d) provides confidentiality solely by means of EncB, but it does not ensure integrity, authenticity, or non-repudiation.

The Protocol (e) utilizes EncS to ensure confidentiality and utilizes digital signature Sign(ml) on the final block of message m to guarantee integrity, authenticity, and non-repudiation.

Imagine you’re interested in the effect of early childhood health interventions on adult wages. You have a panel dataset on adult individuals from age 18 to 25. What is your model? Is the panel data structure helpful in answering this question? You are especially concerned with time-invariant unobservables causing endogeneity of whether adults experienced early childhood health interventions. Is it possible to address this? What are key concerns of endogeneity? What are key concerns for validity of standard errors?

Answers

To analyze the effect of early childhood health interventions on adult wages using a panel dataset of individuals aged 18 to 25, a suitable model would be a fixed-effects panel regression model.

The panel data structure is helpful in answering this question as it allows for controlling individual-specific characteristics that may affect both early childhood health interventions and adult wages. However, concerns arise due to the potential endogeneity caused by time-invariant unobservables. To address this issue, instrumental variables (IV) or fixed-effects instrumental variables (FEIV) estimation can be employed to account for the endogeneity and obtain consistent estimates. Validity of standard errors should also be considered, and robust standard errors or cluster-robust standard errors can be used to address potential heteroskedasticity or clustering within the data.

In studying the effect of early childhood health interventions on adult wages, a fixed-effects panel regression model is appropriate. This model allows for controlling individual-specific characteristics that may influence both the likelihood of experiencing early childhood health interventions and adult wages. The panel data structure is advantageous as it captures individual variation over time and provides more reliable estimates compared to cross-sectional data.

However, a key concern in this analysis is the potential endogeneity arising from time-invariant unobservables. These unobservable factors may affect both the likelihood of receiving early childhood health interventions and future wages. To address this issue, instrumental variables (IV) or fixed-effects instrumental variables (FEIV) estimation can be employed. Suitable instrumental variables are those that are correlated with the early childhood health interventions but not directly associated with adult wages, ensuring that the IV assumptions are satisfied. Another important consideration is the validity of standard errors. Standard errors are crucial for hypothesis testing and assessing the precision of estimated coefficients. In the presence of heteroskedasticity or clustering within the data, the assumption of homoskedasticity underlying ordinary least squares (OLS) regression may be violated. To address this, robust standard errors or cluster-robust standard errors can be used, which provide more accurate inference.

Overall, by employing a fixed-effects panel regression model, addressing endogeneity through instrumental variables, and considering the validity of standard errors, it is possible to investigate the effect of early childhood health interventions on adult wages while mitigating potential biases and obtaining reliable estimates.

  The SSL (Secure Sockets Layer) data transport protocol involves two nonces and a premaster key to establish a secure and encrypted connection between a client and a server.

  Nonces are used in SSL to ensure the uniqueness and freshness of data exchanged during the handshake process. The first nonce, called the client nonce or client random, is generated by the client and sent to the server. The second nonce, called the server nonce or server random, is generated by the server and sent to the client. These nonces play a crucial role in the generation of session keys and preventing replay attacks.

  The premaster key is a shared secret between the client and the server. It is generated during the handshake process using various cryptographic algorithms and is used to derive the symmetric session key that will be used for encrypting and decrypting data during the SSL session.

Yes, it is possible for the same MAC address to appear in both ARP tables of the router in Figure 1. ARP (Address Resolution Protocol) is used by routers to map an IP address to its corresponding MAC address.

Yes, it is possible for the same MAC address to appear in both ARP tables of the router in Figure 1. ARP (Address Resolution Protocol) is used by routers to map an IP address to its corresponding MAC address. When a router receives a packet with a destination IP address that it does not know, it sends an ARP request to find the MAC address of the destination device. The response to this request is stored in the router's ARP table, which is used for future packet forwarding.
Since the router in Figure 1 has two ARP modules, it means that it can handle ARP requests for two different subnets. Each ARP module will maintain its own ARP table, which will contain the MAC addresses of devices on its respective subnet. However, it is possible for a device to have multiple IP addresses, each belonging to a different subnet. In this case, if the router receives an ARP request for one of these IP addresses, the same MAC address will appear in both ARP tables.

5) What is the execution time of one single iteration on all 3 architectures with and without forwarding?
6) What is the total execution time of the entire code on all 3 architectures with and without forwarding

Answers

The effective total number of instructions in this snippet is 6.

Hazards/dependencies in the code:

a) Data hazard between the addi instruction and the lw instruction. The result of the addi instruction is needed as an operand for the lw instruction.

b) Data hazard between the lw instruction and the first add instruction. The result of the lw instruction is needed as an operand for the add instruction.

c) Control hazard due to the branch instruction. The branch instruction depends on the comparison result of the beq instruction.
