(40%) A bank wants to store the account number of its customers (an 8-digit number) in encrypted form on magnetic stripe ATM car

ds. Discuss the security of the following methods for storing the account number against an attacker who can read the magnetic stripe: (1) store a cryptographic hash of the account number; (2) store the ciphertext of the account number encrypted with the bank's public key using a public-key cryptosystem; (3) store the ciphertext of the account number encrypted with the bank's secret key using a symmetric cryptosystem.

Answer:

e_{ab} =  4.18*10^(-3)

Explanation:

This question will be solved with the help of diagram (see attachment)

Given:

Δ∅ = 0.50 degrees (correction)

BC = 800 mm

AC = 600 mm

Solution:

We use coordinate system with point C as origin (0,0)

Hence,

Point A = (600,0)

Point B = (0,800)

The change in length or displacement can be calculated BB' :

BB' = BC * tan (Δ∅) = (800 mm) * tan (0.5) = 6.9815 mm

Hence, Point B' = (-6.9815,800) and we calculate distance A and B

AB = \sqrt{600^2 + 800^2} = 1000 mm

We calculate distance A and B'

AB' = \sqrt{(600 - (-6.9815))^2 + (0-800)^2} = 1004.2 mm

Normal Strain in AB is:

e_{ab} = \frac{AB' - AB}{AB} \\\\= \frac{1004.2 - 1000}{100}\\\\= 4.18 * 10^(-3)

The solution is :

e_{ab} =  4.18 * 10^(-3)
