Question 2
This question carries 30% of the marks for this assignment
Flexible displays are considered as one of the biggest revolutions in mobile phone designs since the advent of
the touchscreen. The research and development in this field reached an advanced stage; some prototypes have
been presented by phone manufacturers in the last years (YOUM from Samsung for instance) and even some
phones have been commercialized with some basic features of flexible displays (curved screens such as in
Galaxy Round from Samsung and G-Flex from LG). However, there are some challenges and issues that are
still to be handled before having full-flexible (bendable) screens in the mobile phone market.
Using the AOU e-library or any Internet reliable resource, you are asked to prepare a short report on flexible
displays for mobile phones. Your report should include the following information:
 Introduction to flexible displays (5 marks)
 Technologies used in flexible displays (at least one) (5 marks)

Question 3
This question carries 40% of the marks for this assignment
As you have seen in Block 2, Public Key Infrastructure is “a combination of services and encryption
techniques that together are used to protect the security of data over networks”. It includes a number of
entities such as: Registration authority, certification authority, directory services and certificate and key
management services. In this question, you are asked to better understand how a certification authority works
by using a simple CA tool named xCA [1]. In particular, you are asked to use1
this tool to:

1- Create a certification authority (CA) that has a self-signed certificate.
a. Generate RSA key pair for the CA (2048 bits)
b. Create a self-signed certificate for the CA using the pair of keys you have generated in step a.
The following fields in the certificate distinguished name should be set as follow:
i. The organization name is AOU
ii. commonName is CA-“your name”
iii. Email address: ca-“your ID”@arabou.org
2- Issue a certificate signing request as follows
a. Generate a new RSA key pairs (1024 bits)
b. Create a certificate signing requests using the pair of keys you have generated in step a. The
following fields in the certificate distinguished name should be set as follows:
i. The organization name is AOU
ii. commonName is “your name”
iii. Email address: your email address
3- Sign the certificate request using the CA certificate you generated in step 1-b

You should follow these steps using the abovementioned tool (xCA) and understand the main inputs and
choices you are asked to do in each step. The explanation of these choices should be included in your answer.
You should refer to your tutor for any help regarding the installation of the tool to avoid unnecessary delays.

The deliverables of this question are:
 A report that explains the different steps you have made. You should take screenshots of each step that
clearly show the inputs (each part can have several screenshots by showing the inputs in each tab of
the GUI). The screenshots should be clear and at the same time you should not use a very high
resolution in order to keep the size of the TMA file reasonable. In addition, you should explain for
each screenshot the different options and choices you have taken (without entering into in-depth
details: for instance when talking about extensions in a certificate, you should explain what do we
mean by extension with one example but without detailing what each extension is about).
 The two certificates you have generated during the exercise. The question will not be validated if the
files are not uploaded along with the TMA (put all TMA files in one zip file and upload it to the TMA
upload activity)
