  With the advent of Internet of Things (IoT) and the increasing use of
application-based processors, security infrastructure needs to be examined on
some widely-used IoT hardware architectures. Applications in today's world are
moving towards IoT concepts as this makes them fast, efficient, modular and
future-proof. However, this leads to a greater security risk as IoT devices
thrive in an ecosystem of co-existence and interconnection. As a result of
these security risks, it is of utmost importance to test the existing
cryptographic ciphers on such devices and determine if they are viable in terms
of swiftness of execution time and memory consumption efficiency. It is also
important to determine if there is a requirement to develop new lightweight
cryptographic ciphers for these devices. This paper hopes to accomplish the
above-mentioned objective by testing various encryption-decryption techniques
on different IoT based devices and creating a comparison of execution speeds
between these devices for a variety of different data sizes. Keywords-Internet
