From: Efficient and secure outsourcing of genomic data storage

Parameters

Description

DATA_HASH_SIZE

Length in bits of a variant’s hash to be stored.

BITS FOR MAPPING = x

Number of bits extracted from the hash that maps to a specific index.

NUM_ENTRIES

Number of entries in the encoded VCF (=2x).

ROW_SIZE

Number of elements per row of d a t a_h a s h_s i z e bits. Indirectly defines the number of dummy elements (padding) to be added.

ENCRYPTION MODE

Cryptographic parameters for the FV scheme: FV:A:B:C:D. FV is to be used with A security bits, polynomials of degree B, polynomial coefficients of C bits and capable of absorbing a maximum of D bits per coefficient.

AGGREGATION

Number of aggregated rows. Ensures that multiple rows are concatenated resulting in a database with a lesser amount of rows (NUM_ENTRIES/AGGREGATION), which are in turn longer (ROW_SIZE × AGGREGATION).

DIMENSIONALITY

Level of recursion.
