Abstract

In [1], they gave the notions of security for the symmetric encryption and provided a concrete security analysis of the XOR, CTR, and CBC schemes. Among the three schemes, the CTR scheme achieves the best concrete security in their analysis. In this paper, we propose the new schemes, CTR-OFB and CTR-CFB, which have the security as same as that of the CTR scheme on the point of the concrete security analysis and achieve higher resistance against some practical attacks than the CTR scheme.
