Cryptanalysis of Koyama Scheme

In this paper we analyze the security of Koyama scheme based on the singular cubic curve for some well known attacks. We provide an efficient algorithm for linearly related plaintext attack and identify isomorphic attack on Koyama scheme. Some other attacks are also discussed in this paper.
