- 19. Solutions(Cont’d) Cryptographic Algorithms ECC - Elliptic Curve Cryptography public-key Cryptography supports authenticated key exchange protocols smaller keys, cipher text and signature very fast key generation fast encryption and decryption uses less memory and CPU cycles An elliptic curve is a plane curve defined by an equation of the form y2 = x3 + ax + b 19 / 25
- 20. Solutions(Cont’d) Cryptographic Algorithms HMAC - Hash Based Message Authentication Code hash function and a secret key verify both the data integrity and the authentication of a message strength depends upon the cryptographic strength of the underlying hash function, the size of its hash output, and on the size and quality of the key. less affected by collisions HMAC(K, m) = H((K ⊕ opad)||H(K ⊕ ipad)||m) 20 / 25
- 23. Conclusion Billions of devices are connected to the Internet Companies behind these devices are not designing them with security in mind Leaving IoT devices unsecured, is like leaving the back door to your house unlocked Various solutions to security challenges were discussed Cryptographic encrytpion techniques like ECC and HMAC can be used to provide better protection 23 / 25
