INTRODUCTION
We are living in a world where the security of data has the upmost priority of all. The world
around us is evolving each and every single minute. Social networking is the powerful aspect
now. People want their life to be easy and needs a smooth movement towards the future. The
developers took this into account to create the next revolution technology – CICRET.
CICRET is the developed based on the cloud technology. Cicret is the technology of the
future. Cicret consists of 2 parts. 1 is the application part and the other is a wearable bracelet.
The Cicret App is the only intuitive, secure and free solution for those who want to chat,
share and exchange safely with no chance of being traceable. The app is an innovative
encrypted technology providing anonymity and full control on all contents you have shared,
even after sending them. It allows you to give all your personal information always with you,
on your arm. The idea came from the opinion that the cloud system is not safe and there is no
other place to protect your digital privacy than yourself. Cicret is the next level technology
that’s easy to adapt to human environment and it would make Google Glass a primitive
technology in the year 2015 when its expected to be released.

ACCELEROMETER
Accelerometers are used to detect and monitor vibration in rotating machinery.
Accelerometers are used in tablet computers and digital cameras so that images on screens
are always displayed upright. Accelerometers are used in drones for flight stabilisation. In
smart phones the display gets tilted automatically to adjust to users view due to the working
of the accelerometer.
In CICRET, when the bracelet is shook twice, it gets activated and when shooked again puts
it in a sleep mode.
MEMORY CARD
A memory card or flash card is an electronic flash memory data storage device used for
storing digital information. These are commonly used in many electronic devices,
including digital cameras, mobile phones, laptop computers, MP3 playersand video game
consoles, Tablets. Most of these can be diminutive, re-recordable, and can retain data without
power. 16 to 32GB is currently available for CICRET.
WIFI COMPONENT
The wifi component enables connection between the smart phone and the CICRET bracelet
as long as there is an internet connection available for the two devices.
MICRO USB PORT
CICRET bracelet has a micro USB port to connect to the system for data transfer between the
system and the bracelet. Exchange of information’s could include images, music, document
etc

PROXIMITY SENSOR (LONG RANGE)
Is a sensor able to detect the presence of nearby objects without any physical contact. A
proximity sensor often emits an electromagnetic field or a beam of electromagnetic
radiation (infrared, for instance), and looks for changes in the field or return signal. The
object being sensed is often referred to as the proximity sensor's target. Different proximity
sensor targets demand different sensors.
The picoprojector projects the interface to our arm. When you place your finger on your
interface, it stops one of the 8 long range PROXIMITY SENSOR. The SENSOR sends back
the information to the processor place in the CICRET bracelet.
BLUETOOTH
When internet connection is unavailable the CICRET app and bracelet can be connected via
Bluetooth and also the Bluetooth can be used to exchange data/information to other devices.
PICOPROJECTOR
It’s technology that applies the use of an image projector in an handheld device. It is a
response to the emergence/development of compact portable devices such as mobile
phones, personal digital assistants, and digital cameras, which have sufficient storage
capacity to handle presentation materials but little space to accommodate an attached display
screen. Handheld projectors involve miniaturized hardware and software that can project
digital images onto any nearby viewing surface
LED
The LED is used to show notifications and is used to show the working of a process.
SNAP BUTTON
The snap button is a power switch that turns the CICRET bracelet on and off.

WORKING
The working of CICRET could be explained in 5 steps.
STEP 1: Download CICRET
STEP 2: ID Generation
STEP 3: AES Key Generation
STEP 4: RSA Key Generation
STEP 5: Encrypted Communication
These 5 steps are explained in detail below to fully understand the proper working of the
CICRET.
STEP 1 :DOWNLOAD CICRET
The CICRET application is available on android play store. Downloading and installation
process is as easy as any app.
STEP 2 :ID GENERATION
As the app gets started for the first time, it asks for user password. When the user password is
entered and is recognized as the key.
STEP 3 :AES KEY GENERATION
The AES stands for Advanced Encryption Standard. This standard was established by the US
NIST(National Institute of Standards and Technologies). AES is based on Rjindael Cipher.
In CICRET,we use AES-256 encryption. The AES 256 has the following peculiarities:
 Key Length : 8
 Block Size : 32 Bytes
 Number of Rounds : 14
AES-256 means that there could be 2256 possible keys. A PC that uses 255keys per second
needs 149 billion years to break AES 256.
A single round in AES-256 consist of 4 stages.
1. Sub-Bytes Transformation
2. Shift Row
3. Mix Columns
4. Add Round Key
The AES algorithm operations are performed on a two dimension array of bytes called States.

AES Encryption
The above figure shows the encryption of the AES 128. Here plain text of 128 bits are copied
to a 4x4 bytes matrix states. A key of M bytes are expanded and added with the states. Based
on the type of AES used, here we use AES-128, we perform 10 rounds of encryption. Where

10. CICRET
10
each round would perform the 4 stages (as mentioned above) based on the number of rounds.
The number of rounds are based on the type of AES used.
AES-128 : 10 Rounds
AES-256 : 14 Rounds
As in the figure showed above, the AES key is expanded each round and is added during the
stage – Add Round Key. W represents the word and the parameters specify the word number.

11. CICRET
11
W[0,3] – Word 0 to Word 3. The figure below shows the key expansion during each round.
STAGE 1 :Add Round Key
In this method, the key is added with the state S to produce a new state S’.

12. CICRET
12
STAGE 2 :Sub-Byte Transformation
In Sub-Byte Transformation, byte by byte transformation takes place.
Each byte in S(row,column) is transformed to S’
(row,column) using S-Box Table. The S-Box Table
diagram is shown below.
In the table above we can see that the hexadecimal 53is replaced with ED.
The figure bellows provides a bit more detailed understanding about Sub Byte
Transformation.

13. CICRET

STAGE 3 :Shift Row
Here in this method, circular left shift happens based on the row number.
STAGE 4 :Mix Column
In this method the matrix is multiplied with a column and the result is stored in another
column in S’.

14. CICRET
14
In AES-256 encryption each method is executed 14 rounds one by one to complete the
encryption. To decrypt the content we need the same key and we need to inverse the
encryption process. Decryption without the key is practically impossible.
The example for AES encryption is shown below:
Here we can see that the message: “GOOD MORNING” is encrypted with the key – 123 and
the encrypted message generated based on its algorithm is:
/gxCvp1k7zQYnYV7MnBoLG1EjxOmLw7cUVrVxUdwQu8=

STEP 4 : RSA KEY GENERATION
RSA is stands for the names of the 3 persons who designed it :Rivest, Shamir, Adleman. RSA
is the first public key cryptosystem and is widely in use for secure data transmission. RSA
follows asymmetric cryptography, which means that we use 2 keys for encryption and
decryption. The 2 keys are:
1) Public Key
2) Private Key
A Public Key which may be known by anybody, can be used to encrypt messages and to
verify signatures. The private key is known only to the recipient to decrypt the message and
create signatures.
Digital Signature
In CICRET, a unique RSA key is generated each time you add a contact and you exchange
with the server.

Conclusion
CICRET is the technology that would revolutionize the way we use and interact with
applications. It is the safest way to exchange information and provides a firm set of data
security encryption and decryption methods that’s. It would replace Google Glass and
wouldn’t be surpassed for another 2-3 years.
