摘要：Designing secure and fast cryptographic primitives
is one of the critical issues in the current era. Several domains,
including Internet of Things (IoT), military and banking, require
fast and secure data encryption over public channels. Most of the
existing stream ciphers are designed to work sequentially and
therefore not utilizing available computing power. Also, other
stream ciphers are designed based on complex mathematical
problems which makes these ciphers slower due to the complex
computations. For this purpose, a novel parallel platform for
enhancing the performance of stream ciphers is presented. The
platform is designed to work efficiently over multi-core
processors using multithreading techniques. The architecture of
the platform relies on independent components that can operate
over multiple cores available on the corresponding
communication ends. Two groups of stream ciphers were
considered as case studies in our experiments. The first category
includes stream ciphers of a sequential design, while the second
category includes parallelizable stream ciphers. Performance
tests and analysis shows that the parallel platform was able to
maximize the encryption throughput of the selected stream
ciphers dramatically. The enhancements on the encryption
throughput is relative to the constructional design of the stream
ciphers. Parallelized stream ciphers (Salsa20, DSP-128, and
ECSC-128) was able to achieve higher throughput compared to
other sequentially designed stream ciphers.
