Measurements of Cryptographic Primitives Execution on Android Devices

The primary data related to the collected data is located in folder Measurement and each device has the corresponding subfolder with the measurement file. The dataset consists of JSON files, each containing measurements of available devices' security primitives execution times. The data was gathered in a span of multiple 250 iterations. Each measurement was taken with a 50 repetitions interval for every primitive. We define the main components of the dataset in the following:

1)    context[] – provides the details about the device and OS including device name, model, battery-related information, Software Development Kit~(SDK) version, and basic technical specification.

2)    benchmarks[] – provides entries per primitive, such as:

i)      name – the overall identification title of the primitive, including paddung and other optional fields;

ii)     params – additional parameters unilized for the execution if any;

iii)   totalRunTimeNs – the overall time of the primitive's execution time;

iv)   metrics[] – provides entries per execution, such as:

(a)   timeNs[] – the collected/processed information of the collected data inluding entries per execution in runs[] and statistical parameters in maximum, minimum, and median.

(b)  warmupIterations – number of iterations of warmup before measurements started;

(c)   repeatIterations – the number of iterations;

(d)  thermalThrottleSleepSeconds – the duration of sleep due to thermal throttling.
