Data Security in Internet of Things

This case study highlights the research assistance provided by TEQ Research Solution for a Ph.D. research project titled “Data Security in Internet of Things” in the domain of IoT Security, Encrypted Databases, and Secure Query Processing. The research focused on developing a secure encrypted query processing framework named IoTCryptDB to enhance data confidentiality, secure query execution, and privacy protection in Internet of Things (IoT) environments.

Problem Statement

IoT applications continuously generate and store sensitive data in cloud and distributed environments. Existing encrypted database systems such as:

·         CryptDB

·         MONOMI

·         SDB

·         TrustedDB

·         Cipherbase

faced several limitations including:

·         Limited query support

·         High execution overhead

·         Poor analytical query handling

·         High latency

·         Resource constraints in IoT devices

·         Weak support for secure aggregation and sub-queries

The implementation of heavy cryptographic schemes on IoT devices also caused challenges related to CPU, memory, bandwidth, and energy consumption.

Proposed Solution

TEQ Research Solution assisted in developing an advanced encrypted database architecture called IoTCryptDB.

The proposed system provided:

·         Secure encrypted query processing

·         Strong data confidentiality

·         Efficient analytical query execution

·         Secure cloud database integration

·         Access control and authentication

·         Improved query response performance

The architecture integrated advanced encryption mechanisms such as:

·         Elliptic Curve Cryptography (ECC)

·         Hash Encryption

·         Aggregation Encryption

·         Analytical Encryption

·         Sub Query Encryption

·         Homomorphic Encryption

The solution enabled efficient encrypted SQL query execution without compromising security performance.
