| Summary: | A few dynamic design stream ciphers have been described in a number of papers. Moreover, the
majority of these papers are just focused on dynamic polynomial switching in the Linear Feedback
Shift Registers. This paper proposed a novel stream cipher with dynamic structure, which is based on
using dynamic parameters to increase the complexity of the cipher. In the proposed cipher, the
dynamic parameters are the number of registers, the length of registers, clocking system, initialization
procedure, confusion and diffusion method, and output function. These parameters are specified using
bits from the secret key. The National Institute of Standards and Technology (NIST) suite is used to
evaluate the randomness of the proposed design, and the results are encouraging. |
