Abstract
In this paper I present a Simple Encryption Algorithm (SEAL), by which 128-bit long blocks can be quickly encrypted/decrypted. The algorithm is designed to run efficiently in software without any specialized hardware while still guaranteeing a strong degree of confidentiality. The cipher is composed entirely of simple bit-wise operations, such as the exclusive-or and circular shift, in addition to modular addition, thereby making it exceedingly easy to implement in most programming languages as well as efficient in terms of performance.
Author Comment
The original version contained some typos in the algorithm's schematic as well as an omission of the inverse substitution box. These have now been corrected in the new version.
