Enhancement MD5 depend on multi techniques

الملخص EN

Hash algorithms are critical part in many cryptography applications and security protocol suites.

This research works on enhancement MD5 algorithm.

The enhancement method depended on multi techniques such as DNA coding, non- Linear Feedback Shift Register (NLFSR), and Logistic function of Chaos theory.

It will expand of input MD5 algorithm to 1024 bits instead of 512 bits, and change output to 160 bits instead of 128 bit.

The complexity try's increase of data input by preprocessing before entrance MD5 operation, where, will use NLFSR and DNA coding in addition the use Logistic function of Chaos theory with each rounds of MD5.

The efficiency of the modified method had proved by several comparative examples.
