Simulation of Security Protocol in Contiki

Time needed: 5 minutes

Follow from Step 1 to Step 7 in order to create Contiki projects. Quick guide to create Security Protocol in Contiki . Reach us , if you want an customize Contiki projects works for scholars.

1. Symmetric encryption

   Symmetric encryption is one of a type of encryption. By use where only one key is used to both encrypt and decrypt electronic information. For make a secure purpose we make a communication between the entities/nodes via symmetric encryption . During the process must exchange the key so that it can be used in the decryption process.
   Some examples of symmetric encryption algorithms include:
   • AES (Advanced Encryption Standard)
   • DES (Data Encryption Standard)
   • IDEA (International Data Encryption Algorithm)
   • Blowfish (Drop-in replacement for DES or IDEA)
   • RC4 (Rivest Cipher 4)
   • RC5 (Rivest Cipher 5)
   • RC6 (Rivest Cipher 6)

2. Asymmetric cryptography

   Asymmetric cryptography is a process of cryptography where a secret key can be divided into two parts,like a public key and a private key. The public key can be access by anyone, the user may be trusted or not, while the private key must be kept secret. And also the Asymmetric cryptography has two primary use cases: authentication and confidentiality. By using asymmetric cryptography, messages are create as a signature with a private key, and then anyone with the public key is able to verify that the message .
   The sample list of sample algorithms are,
   RSA Asymmetric Encryption Algorithm
   ECC Asymmetric Encryption Algorithm

3. Hybrid Encryption: Symmetric + Asymmetric Encryption

   The hybrid encryption technique is used in applications such as SSL/TLS certificates. SSL/TLS encryption is applied during a series of perform the communications between servers and clients. During the communication we identity of both parties is verified using the private and public key. Once both parties have confirmed their identities, the encryption of the data takes place through symmetric encryption using session key.
   Protocols in the cooja tool
   for example , we will implement the AES algorithm.

4. Open the terminal and verify the installed package

   Initially,Next open the terminal by press ctrl+alt+T buttons or search from the installed software list.

5. Change the location

   Change the contiki installation location in the terminal, using the command cd contiki/tools/cooja

6. Execute the command

   For get the simulation , execute the command ant run , in the terminal

7. Open the simulation

   We open the simulation, by goto file menu and open simulation option ->Start the simulation
