A secure order-preserving indexing scheme for outsourced data

Somayeh Sobati Moghadam, Gerald Gavint, Jerome Darmonti

We enable this by encrypting IoT data with a set of cryptographic schemes such as order-preserving and partially homomorphic encryptions.  ...  To achieve this on resource-limited devices, our system relies on optimized algorithms that accelerate partial homomorphic and orderpreserving encryptions by 1 to 2 orders of magnitude.  ...  For instance, the UDF for an ordering-related query (e.g., order by, MAX, MIN) is aware of the order-preserving encryption and computes the result without access to the plaintext values.  ...
