of the tremendous development in the field of information technology and the internet and exposure to a
flood of violations to circumvent and steal information organized and unorganized. The urgent need for
the emergence of data protection technologies and data encryption techniques one of these methods, The
Salsa20 encryption stream and all of its reduced versions Salsa20 / 7 and Salsa20 / 12 are among the fastest
stream ciphers today. In this paper, the Salsa20 method is therefore improved by adding a new variable by
using chaos theory which can achieve faster propagation than the original Salsa20 and has been applied by
encrypting medical images that need confidentiality because some patients do not want anyone to know
about a disease so the patient’s medical data is encrypted and no one can access it. This method has been
tested and measured with the original Salsa20 with a series of tests. Most tests show that the proposed messy
salsa is faster than the original salsa.
