Abstract
The significant benefits of cloud computing (CC) resulted in an explosion of their usage in the last several years. From the
security perspective, CC systems have to offer solutions that fulfil international standards and regulations. In this paper, we
propose a model for a hash function having a scalable output. The model is based on an artificial neural network trained to
mimic the chaotic behaviour of the Mackey–Glass time series. This hashing method can be used for data integrity checking
and digital signature generation. It enables constructing cryptographic services according to the user requirements and
time constraints due to scalable output. Extensive simulation experiments are conduced to prove its cryptographic strength,
including three tests: a bit prediction test, a series test, and a Hamming distance test. Additionally, flexible hashing function
performance tests are run using the CloudSim simulator mimicking a cloud with a global scheduler to investigate the
possibility of idle time consumption of virtual machines that may be spent on the scalable hashing protocol. The results
obtained show that the proposed hashing method can be used for building light cryptographic protocols. It also enables
incorporating the integrity checking algorithm that lowers the idle time of virtual machines during batch task processing.
