摘要：
The Okamoto cryptosystems1 have drawn attention for their properties of fast encryption and decryption. A probabilistic attack based on the L3 algorithm was proposed by Vallee et al. Other attacks have also been proposed. In the letter, a very simple and fast attack with continued fractions is given, which can completely break the Okamoto cryptosystems.
