Abstract :
A blocking method for the RSA cryptosystem is presented. It causes no expansion in block size by encipherment. The heart of the proposed method is the encryption function which involves two RSA encryptions interleaved with a domain interchanging function. This method enables easy adoption of the RSA cryptosystem to already established systems. Moreover, this method is a simple solution to the reblocking problem.
