The summarized steps below are a description of how the protocol functions. 1. With at least two Apple devices, the user’s Apple devices create a shared private key communicated among them via end-to-end encryption. 2.

If Find My is enabled on a device, it emits its current public key via Bluetooth and other Apple devices nearby can pick up on the broadcast. 4. A device that has picked up a public key will then check its own location, encrypt the location using the public key, and upload this to Apple’s servers along with a hash of the public key. 5. With a different Apple device, a user can then query Apple’s servers with hashes of the public keys it has used to get the encrypted location associated with the hashed public key. 6.

Due Date: 10/9
Points: 15
In June 2019, at the Worldwide Developers Conference
(WWDC), Apple announced a new iOS and OSX feature called
‘Find My.’ Combining the features of Find My iPhone and Find
My Friends into a single application. The summarized steps
below are a description of how the protocol functions.
1. With at least two Apple devices, the user’s Apple devices
create a shared private key communicated among them via end-
to-end encryption.
2. Each pair of devices periodically creates a new secret key
and public key pair using a deterministic algorithm applied to
the previous secret key. This is also referred to as rotation of
keys.

2. 3. If Find My is enabled on a device, it emits its current public
key via Bluetooth and other Apple devices nearby can pick up
on the broadcast.
4. A device that has picked up a public key will then check its
own location, encrypt the location using the public key, and
upload this to Apple’s servers along with a hash of the public
key.
5. With a different Apple device, a user can then query Apple’s
servers with hashes of the public keys it has used to get the
encrypted location associated with the hashed public key.
6. Using the original secret key, the user can decrypt and get the
location of their lost device.

The questions below, consider potential attackers to include
someone who has stolen the user’s device, other users who have
Apple devices, and Apple employees with Find My database
access.
Answer the following questions:
1.) In step 2, why are the public keys periodically updated?
What security properties are provided by updating the public
key?
2.) For the encryption in step 4, what security properties must
the encryption algorithm have for this to be secure?

3. 3.) Can you come up with ways to attack the Find My protocol
even assuming that the cryptographic primitives used in the
protocol are secure? Some ideas worth considering are who are
the trusted parties/ devices in the protocol, and who generates
what data in this protocol.

SURVEY COMPLETION DATE: 09-27-2022
Many years of research conducted by The Gallup Organization
suggest that the most effective people are
those who understand their strengths and behaviors. These
people are best able to develop strategies to
meet and exceed the demands of their daily lives, their careers,
and their families.
A review of the knowledge and skills you have acquired can

4. provide a basic sense of your abilities, but an
awareness and understanding of your natural talents will
provide true insight into the core reasons behind
your consistent successes.
Your Signature Themes report presents your five most dominant
themes of talent, in the rank order
revealed by your responses to StrengthsFinder. Of the 34 themes
measured, these are your "top five."
Your Signature Themes are very important in maximizing the
talents that lead to your successes. By
focusing on your Signature Themes, separately and in
combination, you can identify your talents, build
them into strengths, and enjoy personal and career success
through consistent, near-perfect performance.
Relator
Relator describes your attitude toward your relationships. In
simple terms, the Relator theme pulls you
toward people you already know. You do not necessarily shy
away from meeting new people—in fact, you
may have other themes that cause you to enjoy the thrill of
turning strangers into friends—but you do
derive a great deal of pleasure and strength from being around
your close friends. You are comfortable
with intimacy. Once the initial connection has been made, you
deliberately encourage a deepening of the
relationship. You want to understand their feelings, their goals,
their fears, and their dreams; and you want
them to understand yours. You know that this kind of closeness
implies a certain amount of risk—you might
be taken advantage of—but you are willing to accept that risk.
For you a relationship has value only if it is
genuine. And the only way to know that is to entrust yourself to
the other person. The more you share with

5. each other, the more you risk together. The more you risk
together, the more each of you proves your
caring is genuine. These are your steps toward real friendship,
and you take them willingly.
Intellection
You like to think. You like mental activity. You like exercising
the “muscles” of your brain, stretching them in
multiple directions. This need for mental activity may be
focused; for example, you may be trying to solve a
79321197 (Zeinab Hazime)

2
problem or develop an idea or understand another person’s
feelings. The exact focus will depend on your
other strengths. On the other hand, this mental activity may
very well lack focus. The theme of Intellection
does not dictate what you are thinking about; it simply
describes that you like to think. You are the kind of
person who enjoys your time alone because it is your time for
musing and reflection. You are introspective.
In a sense you are your own best companion, as you pose
yourself questions and try out answers on
yourself to see how they sound. This introspection may lead you
to a slight sense of discontent as you
compare what you are actually doing with all the thoughts and
ideas that your mind conceives. Or this
introspection may tend toward more pragmatic matters such as
the events of the day or a conversation that
you plan to have later. Wherever it leads you, this mental hum
is one of the constants of your life.

6. Includer
“Stretch the circle wider.” This is the philosophy around which
you orient your life. You want to include
people and make them feel part of the group. In direct contrast
to those who are drawn only to exclusive
groups, you actively avoid those groups that exclude others.
You want to expand the group so that as
many people as possible can benefit from its support. You hate
the sight of someone on the outside
looking in. You want to draw them in so that they can feel the
warmth of the group. You are an instinctively
accepting person. Regardless of race or sex or nationality or
personality or faith, you cast few judgments.
Judgments can hurt a person’s feelings. Why do that if you
don’t have to? Your accepting nature does not
necessarily rest on a belief that each of us is different and that
one should respect these differences.
Rather, it rests on your conviction that fundamentally we are all
the same. We are all equally important.
Thus, no one should be ignored. Each of us should be included.
It is the least we all deserve.
Ideation
You are fascinated by ideas. What is an idea? An idea is a
concept, the best explanation of the most
events. You are delighted when you discover beneath the
complex surface an elegantly simple concept to
explain why things are the way they are. An idea is a
connection. Yours is the kind of mind that is always
looking for connections, and so you are intrigued when
seemingly disparate phenomena can be linked by
an obscure connection. An idea is a new perspective on familiar
challenges. You revel in taking the world
we all know and turning it around so we can view it from a
strange but strangely enlightening angle. You

7. love all these ideas because they are profound, because they are
novel, because they are clarifying,
because they are contrary, because they are bizarre. For all
these reasons you derive a jolt of energy
whenever a new idea occurs to you. Others may label you
creative or original or conceptual or even smart.
Perhaps you are all of these. Who can be sure? What you are
sure of is that ideas are thrilling. And on
most days this is enough.

Restorative
You love to solve problems. Whereas some are dismayed when
they encounter yet another breakdown,
you can be energized by it. You enjoy the challenge of
analyzing the symptoms, identifying what is wrong,
and finding the solution. You may prefer practical problems or
conceptual ones or personal ones. You may
seek out specific kinds of problems that you have met many
times before and that you are confident you
can fix. Or you may feel the greatest push when faced with
complex and unfamiliar problems. Your exact
preferences are determined by your other themes and
experiences. But what is certain is that you enjoy
bringing things back to life. It is a wonderful feeling to identify
the undermining factor(s), eradicate them,
and restore something to its true glory. Intuitively, you know
that without your intervention, this thing—this
machine, this technique, this person, this company—might have
ceased to function. You fixed it,

8. resuscitated it, rekindled its vitality. Phrasing it the way you
might, you saved it.

What makes great leaders great? Every leader is different, of
course, but one area of commonality is the leadership
philosophy that great leaders develop and practice. A leadership
philosophy is basically an attitude held by leaders that acts as a
guiding principle for their behavior. While formal theories on
leadership continue to evolve over time, great leaders seem to
adhere to an overarching philosophy that steers their actions.
What is your leadership philosophy? In this Assignment, you
will explore what guides your own leadership.
To Prepare:
· Identify two to three scholarly resources, in addition to this
Module’s readings, that evaluate the impact of leadership
behaviors in creating healthy work environments.
· Reflect on the leadership behaviors presented in the three
resources that you selected for review.
· Reflect on your results of the CliftonStrengths Assessment*,
and consider how the results relate to your leadership traits.
*not required to submit CliftonStrengths Assessment
The Assignment (2-3 pages):
Personal Leadership Philosophies
Develop and submit a personal leadership philosophy that
reflects what you think are characteristics of a good leader. Use
the scholarly resources on leadership you selected to support
your philosophy statement. Your personal leadership philosophy
should include the following:
· A description of your core values.

9. · A personal mission and vision statement.
· An analysis of your CliftonStrengths Assessment summarizing
the results of your profile
· A description of two key behaviors that you wish to
strengthen.
· A development plan that explains how you plan to improve
upon the two key behaviors you selected and an explanation of
how you plan to achieve your personal vision. Be specific and
provide examples.
· Be sure to incorporate your colleagues’ feedback on your
CliftonStrengths Assessment from this Module’s Discussion 2.

and for my peer feedback this is what someone responded to
me:
In reading your post, I see your results are similar to my self-
assessment results. As you mentioned, I also have quite a few
friends I have known most of my life. I enjoy meeting new
people as well and have added a couple of new people to my
circle. However, I find that people these days are not as genuine
as my long-time friends.
Like you, I enjoy learning and researching various random
topics. Learning about the past, how things happened, and the
trials we have gone through as a human race is interesting to

10. me.
What I have discovered is that much of history has been
rewritten or even hidden. However, and fortunately, many
secrets were written in very old publications, in times such as
the early 1800s and before. Those are great finds when you can
get a hold of republished books.
As with you, I am an inclusive person. I can empathize with
people’s situations and seek to comfort or include them if they
are a loner or stand-offish. These are skills that we both possess
as known qualities of a leader. It signifies that we can manage a
team and include all followers (Rath, 2007).
Part of being a great leader is how one relates to people; to
mentor, encourage, motivate and affect them positively
(Quesado et al., 2022). Inclusiveness is vital when holding a
leadership role in a team/organization (Broome & Marshall,
2021).
