Cicret is an innovative product combining a mobile app and a bracelet that transforms the skin into a touchscreen, enabling features like messaging, music playback, and call answering. It employs advanced AES-256 encryption for secure communications and incorporates components such as an accelerometer, micro USB port, proximity sensor, and pico projector. This project, developed by Pranav Misra, aims to enhance user control and data privacy.

8. Cicret Bracelet – Components
*Accelerometer
Most commonly found on drones for flight stabilization

9. Cicret Bracelet – Components
*Micro USB port
Exchange information between the system & bracelet.
Data to be exchanged includes :
- Images & Videos
- Documents etc…

10. Cicret Bracelet – Components
*Proximity Sensor
Emits electromagnetic field/ beam
Looks for change in field/return signal
When hand placed : stops one of the 8 sensor and sends
information back to the processor

13. Cicret – Working
Step 1 : Download Cicret
Step 2 : ID Generation
Step 3 : AES Key Generation
Step 4 : Encrypted Communication

14. Cicret – Working
AES
- Advanced Encryption Standard
- Established by US NIST
- Cicret uses AES-256 encryption -> 2256 possible keys
Block Size : 4
Key Length : 32 bytes
No. Rounds : 14
- 14 rounds of encryption performed
- Use Symmetric Block Cipher
- Cipher?
- Symmetric Block Cipher?

15. Cicret – Working
Single Round consists of 4 Stages:
a) Add Round Key
b) Substitute Bytes
c) Shift Rows
d) Mix Columns
Since 14 rounds are used, 14 times these 4 stages are
performed one after the other sequentially.

16. Cicret – Working
AES – 128
- uses 128 bit block
- represented in 4X4 matrix
- 1 word = 16 bytes

RSA Key generation
- Creators : Rivest, Shamir, Adleman
- Follows asymmetric cryptography
- Asymmetric cryptography?
- Public & Private Keys?
- Unique RSA key generated
each time when data is
exchanged with server.
