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.

WHAT IS CICRET CICRET is the combination of two parts

1) CICRET APP

2) CICRET BRACELET

It’s the combination of two products with a single idea: to give you the control.

CICRET APP

The CICRET is the only intuitive, secure and free solution for those who want to chat, share and exchange safely with no chance of being traceable. It’s an innovative encrypted

technology providing anonymity and full control on all contents you have shared, even after sending them. The CICRET app available on Android.

Features:

Timer : Define the life time of your outbox contents, by the duration or by the

number of views.

Edit : Remotely adjust whatever you sent.

Delete : Remotely erase whatever you wrote.

Exchange whatever you want with whoever you want (Pictures, Videos, Document,

Notes, Audio etc…)

Stores a file on your computer and remotely gets it back on your smart phone via

CICRET

Only those to whom you gave your ID, CICRET can contact you and vice versa.

Data access at anywhere at any time.

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.

BATTERY

CICRET uses a battery that is to provide 8 hours of lifetime continuously.

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

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.

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’.

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.

CICRET

13

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’.

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=

CICRET

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.
