This paper presents a secure integer arithmeticcode that owns the capabilities of compression and encryption simultaneously. It is quite different from the randomized arithmeticcode, the interval splitting arithmeticcode, and the secure arithmetic code. All of them are applied to float-point arithmetic coding. Instead of float-point implementation, integer implementation is more popular since it can decrease the computational cost of arithmetic coding without inducing significant compression loss. During the implementation of integer arithmetic coding, we find that it is possible to lower the instantaneous entropy through the adjustment of interval size. Hence, we can design a secure integer arithmeticcode (SIAC) with high security, and the compression efficiency of this code is almost the same or even higher than that of the traditional integer arithmeticcode (TIAC).
