Question # 5.

a. Pretty Good Privacy (PGP) is broadly used to secure email communication. Explain the steps needed prior to exchanging email messages with privacy and authenticity guarantees for a pair of users using PGP.

b. Estimate the time required to crack a 56-bit DES key by a brute-force attack using a 3000 MIPS (million instructions per second) computer, assuming that the inner loop for a brute-force attack program involves around 15 instructions per key value, plus the time to encrypt an 8-byte plaintext. Perform the same calculation fora 128-bit IDEA key.

Extrapolate your calculations to obtain the cracking time fora 300,000 MIPS parallel processor (or an Internet consortium with similar processing power).

Question options:

Will iron(III) hydroxide precipitate from a pH = 1.00 solution with [Fe3+] = 1.0 x 10-5? Ksp Fe(OH)3 = 6.3 x 10-38

A 5.171 g sample of a solid, weak, monoprotic acid is used to make a 100.0 mL solution. 26.00 mL of the resulting acid solution is then titrated with 0.09671 MNaOH. The pH after the addition of15.00 mL of the base is 5.51, and the endpoint is reached after the addition of 47.85 mL of the base.

(c) What is the pK_a of the acid?

1. Creep is one of deformation that occurred in concrete structure. Give one example that can be associated with creep problem in concrete structure. Define what is creep and discuss on how the creep occurred in choosen example.

2. Moisture movement in concrete is one of the factor that influencing shrinkage and creep. Elaborate this effect and how to differentiate between these properties.

3. With coastal and offshore concrete structures directly exposed to seawater, why does most of the deterioration occur in the tidal zone? From the surface to the interior of concrete, what is the typical pattern of chemical attack in sea structures? Discuss the mechanism for the chemical attack in the structures.

4. Concrete has been used since ages. In your opinon, how is relavant the advanced knowledge in concreting for the construction industries.

Why does a particular codon represent only one specific amino acid?

Write a function template sort that takes two references to generic objects and switches them if the first argument is larger than the second. It is only assumed that operator<() and a default constructor are defined for the objects considered.
