Within this philosophy of religion, the theory concerning the attributes of God, in Unification Thought, is called the Theory of the Original Image. The original Image refers to the attributes of God, the causal being. These attributes consist of form and function including nature, character, ability, creativity and virtues. Within this framework the idea of Logos is explored.
The attributes of God are expressed in various ways by various religions. Unification Thought examines God’s character and attributes as The Divine Character and The Divine Image. These form as the Original Image, the hallmarks of God’s traits. In this, the first presentation of three, a ground of being is established by examining the fundamental properties of creator and created. It is from this first proposition that a ‘theory of resemblance’ can also be formed where humankind might come to resemble the nature of the creator and by doing so, sustain the virtues evident throughout such a cosmology.
Friedrich Schiller suggested that a culture in chaos cannot perceive principles. By examining the nature of the creator as a ground of being, self can then be viewed as an authentic or true self holding to innate properties and virtues; it is these qualities which affirm principles. From these universal qualities and creative and cultural dynamics, Schiller’s question can then be answered. Principles placed on the ground and rooted in harmony are examined in this presentation. It is only through a correct and full understanding of the Divine Image, as well as the Divine Character, will we be able to fundamentally solve the problems of human life, society, history, and the world. This presentation is followed by Ontology and The Theory of The Original Image, which together present a clear picture of a ground, of being and healthy cultural expressions.

The History of Cryptography
It must be that as soon as a culture has reached a certain level, probably measured largely by its literacy, cryptography appears spontaneously--as its parents, language, and writing probably also did. The multiple human needs and desires that demand privacy among two or more people in the midst of social life must inevitably lead to cryptology wherever men thrive and wherever they write (Kahn, 1996, p. 84).

. New York, NY: Scribner.
Cryptography:
Cryptography is a discipline that embodies principles and methods for the transformation of data to hide its meaning, establish its authenticity; and prevent its undetected modification, repudiation, and unauthorized use. Cryptography is an old art. We know that the ancient Egyptians were using cryptographic techniques in 1900 B.C. The oldest known example is on the tomb of the Egyptian nobleman Khnumhotep II. For more of this history, you might find a tour of the National Security Agency's National Cryptologic Museum interesting, but this is not required for this class. The National Cryptologic Museum tour can be accessed at the following link:

Forms of cryptography:
There are two basic forms of cryptography:
secret-key cryptography
and
public-key cryptography
. These forms of cryptography are different because they use
cryptographic keys
in different ways.
Secret-key cryptography:
Secret key cryptography is the original form of cryptography. Let us deal with text at this point, and think of text as a string of characters. An understandable string of characters is called a
plaintext
. If we have a plaintext and we want to hide its meaning, there are basically two things we can do: We can rearrange the letters in the plaintext, or we can substitute the letters in the plaintext with other letters. These are the two forms of
secret writing
. They are called
transposition
and
substitution
methods, respectively. The text that results from encryption, which is the application of cryptography, is called the
ciphertext
.

This is the presentation I gave at OggCamp 2009. It is a high level overview of various methods of producing trust and then using them on untrustworthy connections. It was mostly recorded (up to the last slide) at http://qik.ly/m6Be
I gave this talk again on the main stage at BarCamp Manchester 2
Cryptography is a method of securing communication and information by encoding messages in such a way that only authorized parties can access it. It involves encrypting plaintext using an algorithm and key to create ciphertext, which can then be decrypted using the same key. Common uses of cryptography include ensuring data privacy, authenticity, integrity, and non-repudiation. Symmetric key encryption uses the same key for encryption and decryption while asymmetric key encryption uses different public and private keys.
Encryption works by encoding information before it is transmitted to protect sensitive data like passwords and personal information. There are two main types of encryption: symmetric-key encryption where both computers use the same secret key, and public-key encryption which uses different keys for encryption and decryption. Encryption along with authentication, which verifies the source and integrity of information, provide security for data transmitted over the internet and between computers.
Cryptography and Symmetric Key Algorithms
Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents.
OR
The art of creating and implementing secret codes and ciphers is known as cryptography.
Cryptography is the study of encrypting information to make it unreadable without authorization. Encryption uses a cipher and key to encode data, hiding its original content. The encrypted data is transmitted and then decrypted at the destination using the same key and cipher to restore the original data. Early forms of encryption included simple substitution ciphers. Modern encryption encrypts data like ATM pins into binary and uses algorithms to encrypt it during transmission, ensuring privacy over insecure networks.
This document proposes a new 3D password authentication scheme that combines multiple existing authentication methods into a 3D virtual environment to provide stronger security. It describes how a 3D password would be composed of a sequence of actions and interactions with various objects in the virtual world. This increases the complexity of guessing passwords compared to traditional text-based passwords. The document also analyzes the potential password key space, security advantages, and applications of the 3D password scheme for critical systems that require strong authentication.
The document discusses post-quantum cryptography and the threats posed by quantum computers. It explains that quantum computers could break current asymmetric cryptographic algorithms like RSA and ECC that secure digital communications. It identifies various attack vectors like the TLS/SSL handshake and digital certificate chain of trust. It also discusses the need for quantum-safe cryptographic systems and how organizations are preparing for a post-quantum future through approaches like hybrid certificates.

Essay On My Favourite Animal Tiger In HindiLisa Long
Social categorization is the process of classifying people into groups based on characteristics like appearance, age, gender, etc. While it helps organize information and form connections, it can also lead to stereotyping. There are pros and cons to social categorization - it allows for efficient processing of information but can promote bias, while categorization based on mutable characteristics is more flexible than immutable ones. Overall, social categorization is a natural cognitive process but should be applied carefully to avoid unfair judgments of individuals.
3-D passwords combine multiple authentication methods like passwords, biometrics, and tokens into a 3-D virtual environment. To log in, a user navigates the environment and interacts with virtual objects in a specific sequence. This creates a large number of possible passwords that are difficult for attackers to guess. The document provides guidelines for designing effective 3-D virtual environments, such as making objects unique and scaling the environment based on the system's security needs. 3-D passwords could protect critical systems and are more secure than traditional text passwords.
Computer encryption uses cryptography to secure online transactions. There are two main types of encryption: symmetric-key encryption where both computers share the same key, and public-key encryption which uses different keys for encryption and decryption. Encryption encodes data during transmission while authentication verifies the identity of the sender and confirms the data has not been altered. Together, encryption and authentication create a secure online environment for sharing information.

Hardware Software
Information Communications
Laptops, Desktop PCs, CPU,
hard disk, storage devices,
cables, etc.
Operating system and software
applications
Personal identification such as
Social Security Number (SSN),
passwords, credit card numbers,
etc.
Emails, instant messengers, and
browsing activites

27. Elements of Security
Authenticity is “the
identification and assurance
of the origin of information”
Confidentiality is “ensuring
that information is accessible
only to those authorized to
have access” (ISO‐17799)
Availability is “ensuring that the
information is accessible to
authorized persons when
required without delay”
Integrity is “ensuring that the
information is accurate,
complete, reliable, and is in its
original form”
Non‐repudiation is “ensuring that a
party to a contract or a communication
cannot deny the authenticity of their
signature on a document”

28. Peran Sandi dalam
Keamanan Informasi
you can’t discuss information security without discussing cryptography
29. SANDI
- Rahasia
- Merahasiakan berita/informasi
PERSANDIAN
- Segala sesuatu tentang rahasia
- Segala sesuatu tentang cara merahasiakan
berita/informasi
- Sandi = Kriptografi (Cryptography)
33. Sistem Sandi Caesar
— Salah satu sistem sandi tertua didunia, skema
sandi sederhana dimana huruf digeser /
disubstitusi dengan huruf ke 3 huruf ke kanan
( A jadi D atau Ts = Tt + 3 )
— Dipakai oleh Julius Caesar untuk
berkomunikasi dengan tentaranya
34. Sistem Sandi Caesar
— Caesar Shift Code
Plain : ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher : DEFGHIJKLMNOPQRSTUVWXYZABC
35. Contoh ENKRIPSI DEKRIPSI
Teks Terang Teks Sandi
— P
— E
— S
— A
— N
— P + 3 = S
— E + 3 = H
— S + 3 = V
— A + 3 = D
— N + 3 = Q
36. Sistem Sandi ROT13
• Menggeser huruf sebanyak 13 huruf
• Karena jumlah huruf ada 26, maka
algoritma (geser13) bisa digunakan
untuk enkripsi dan dekripsi
• Lihat situs http://www.rot13.com
• Dapat digunakan untuk tebak-tebakan
37. Contoh ROT13
Apa bedanya handphone
dan monyet?
Jawaban:
Xnynh unaqcubar, abxvn. Xnynh zbalr, ah
xvrh
39. Confidentiality = kerahasiaan
— Sandi/Kriptografi membuat pesan hanya
dapat dimengerti oleh pihak-pihak yang
berwenang saja.
— Dengan sandi penyadapan masih dapat
dilakukan, namun pesan tidak dapat
dimengerti oleh penyadap.
40. Kerahasiaan Pesan : tidak disandi
To Bob : Halo Say..
Jiah..
dia lagi
Pacaran
…
42. Integritas Pesan
— Sandi memastikan agar pesan yang diterima
sama dengan pesan yang dikirim.
— Teknik sandi yang digunakan biasanya hash
function
— Contoh Md5
43. Integritas Pesan : modifikasi
Pergi yuk
Say..
Gw
kerjain
loe…
To Bob :
Pergi yuk
Say..
From Alice
:
Putus yuk
Say..
Putus yuk
Say..
44. Integritas Pesan : verifikasi
Pergi yuk
Say..
(xxy)
Gw
kerjain
loe…
To Bob :
Pergi yuk say..
(xxy)
From Alice
:
Putus yuk
Say..
Putus yuk
Say..
Ga ada
(xxy)..
Ini mah
bukan
dari
Alice..
45. Otentikasi
— Sandi menghambat pihak tidak berwenang
untuk mengakses pesan/informasi.
— Password untuk proteksi data biasanya
disimpan dalam bentuk tersandi.
51. lSteganografi (steganography)
àilmu dan seni menyembunyikan pesan
rahasia (hiding message)
lBerasal dari Bahasa Yunani yang berarti
“tulisan tersembunyi” (covered writing).
52. lSteganografi membutuhkan dua properti:
wadah penampung
data rahasia yang akan disembunyikan.
lSteganografi dapat dipandang sebagai
kelanjutan kriptografi
53. Sejarah
lYunani à Herodatus,
Rambut prajurit dibotaki, lalu pesan rahasia
ditulis pada kulit kepala prajurit tsb.
lBangsa Romawi
menggunakan tinta tak-tampak (invisible ink).
Tinta tersebut dibuat dari campuran saribuah,
susu, dan cuka.
54. jika aku menangis
selalu aku teringat upayamu
memang akan lebih afdol melihatmu
bolehkah orang mengetahui?
mengapa embun luluh, embun di atas kota
apa pesan
tersembunyinya?

61. “Kekuatan sebuah rantai terletak pada anak
rantai yang paling lemah”
— Secanggih apapun sistem anda..
— Sesulit apapun kriptografi anda..
— Akan percuma apabila…
Passwordnya mudah ditebak!
62. Tips memilih password yang kuat!
— Jangan memilih password dari kata yang ada
di Kamus!
— Jangan pilih password dari Hari Ultah, Nama
Pacar/Ortu, dlsb.
— Campurlah Huruf dan Abjad, dan apabila
memungkinkan karakter khusus (contoh * &
^ ! @ )
— Gunakan campuran huruf besar dan huruf
kecil
— Semakin panjang semakin baik!
