Our team worked on a Cryptography project. Our project was designed to convert a normal message or text to private and secure cipher text to maintain confidentiality and security in both corporate and national security. Here the plain text is converted into cipher text through a web platform where the user submits the confidential plain text and get the cipher text for the corresponding plain text.

Encryption is a process of converting a message, image, or any other .pdfrachanaprade
Encryption is a process of converting a message, image, or any other form of data into encoded
data that can only be decoded by someone who can decrypt the message (usually with a key or
the like). The science of writing secret codes is called cryptography For thousands of years,
cryptography has made secret messages that only the sender and recipient could read, even if
someone captured the messenger and read the coded message. A secret code system is called a
cipher. A good encryption algorithm should produce output that looks random to a bystander but
is easily decipherable with the correct key. Thus, encryption algorithms make use of pseudo-
random encryption keys. Let's start with some definitions: - Encryption or Enciphering: the
process of encoding messages to make them unreadable. This algorithm has two inputs: a
plaintext and a secret key. - Decryption or deciphering: making encrypted messages readable
again by decoding them (recovering the plaintext from ciphertext). - Cipher: an algorithm for
performing encryption and decryption. - Plaintext: the original message. - Ciphertext: the
encrypted message. Note: a ciphertext still contains all of the original message information, even
if it looks nonsense. - Secret key; the same key used for encryption and decryption. -
Cryptography, the science of studying ciphers. For this project, you need to develop a game that
converts normal English words into secret codes. In order to convert, the program randomly
applies an encryption algorithm to any given message. The algorithms you need to implement
include Substitution, Playfais Caesas Transposition, Product, and RSA ciphers. 1. Substitution
cipher, replacing each letter of the alphabet in the plaintext with a different letter in the
ciphertext. For example, if you want to encrypt the word 'Cat', you need to come up with a
substitution for each plaintext letter to a ciphertext letter. For example, you may substitute the
letter ' a ' with the letter ' o '. The rule is that the letter we substitute can only be used once. So,
the letter 'o' is crossed off as it has already been used. The same would be applied to all
alphabetic letters.

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).

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
.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

PROJECT DESCRIPTION
CAESAR CIPIHER: -
It is a platform where the users enjoy the various types of cipher
codes from the noob level to the pro level. In this people will find
various algorithms to encrypt and decrypt the code. like
alphabetic, polyalphabetic substitution, alphanumeric, etc.
3. 3
Important points; -
Encryption-Decryption: -
encryption is the process of converting
data, within a database, in plain text
format into a meaningless cipher text by
means of a suitable algorithm.
decryption is converting the
meaningless cipher text into the original
information using keys generated by the
encryption algorithms
Plaintext: -
Let’s start with the most basic term to
know, which is simple but just as
important as the others: plaintext is a
readable, plain message that anyone
can read.
Cipher text: -
It is the result of the encryption
process. The encrypted plaintext
appears as apparently random strings
of characters, rendering them
useless. A cipher is another way of
referring to the encryption algorithm
that transforms the plaintext, hence
the term cipher text.
Keys: -
The encryption process requires
a cryptographic key that tells the
algorithm how to transform the
plaintext into cipher text
Hash: -
Hashing is generating a value or
values from a string of text using
a mathematical function.
5. Our project shows the power of security at its peak . With the help
of cryptography now one can make their conversation private that
other will never be knowing.It can help in keeping one’s important
information safe.
We have completed our project in three stages like noob,
intermediate and ended it with the creation of our own very cipher
text.
1. The noob level comprises of the ancient cipher text name
before the great Julius Caeser, he used this method of
communication so no other but the person he is sending the text
will only understand it.
2. the intermediate level is a polyalphabetic cipher because it
uses two or more cipher alphabets to encrypt the data. In other
words, the letters in the Vigenère cipher are shifted by different
amounts, normally done using a word or phrase as the encryption
key .
3. And it ended with the creation of our own cipher text with our
own algorithm. Where the plain text is getting converted into
alphanumeric cipher text.
After that we created a website in which we uploaded our
cipher’s. So one can enjoy the benefit from any part of their world
at their finger tips.
This project is just not about encryption but at this stage
where nothing is secure cryptography is the only solution so that
we can protect our valuable documents safe and protect it from
getting vulnerable which in turn reduces the breech of security.
