ENANCHING IOT SECURITY BY HOMOMORPHIC ENCRYPTION

BYV. MURUGESANM.K.S MAHESHM. SIDDHARTH

ABSTRACT• In general, by the concept of Internet of Things (IoT), everything real becomes virtual, which means that every person and thing has a locatable, addressable, and readable counterpart on the Internet. This scenario must be protected at most, which is less expected by the current security level of IoT. Encryption had always proven to be the best way of securing the data in any system. But the current Light weight encryption in IoT provide security only in the client side as it is end to end encryption but not in the server side. This vulnerability can be patched by the advent of Homomorphic encryption which is proven to the best encryption technique in the server side. This latest technique allows performing operations even in the encrypted, irrespective of its type of encryption.

What the Problem is

• IoT generally means connecting every living and non-living things with internet, (i.e.) with server, the data from the things are been transmitted. For security this data undergo several encryption and decryption process for securing and performing manipulation.

• This may increase the time of transmission and also results in the security lacking of the data for some moments.

Why ENCRYPTION• All data sent via the Internet of Things (IOT) needs to be secured with encryption.

Lightweight encryption• We adopt lightweight cryptography because, efficiency of end to end communication and applicability to lower resource devices.

• Application of lightweight symmetric key algorithm will lower energy consumption for end devices.

For server side privacy and security

Homomorphic encryption

Why homomorphic encryption?

Homomorphic encryption for the data shared by the things
