Attack on A New Public Key Cryptosystem from ISC'02 (LNCS 2433)
In ISC 2002, J. Zheng [8] proposed a new public key cryptosystem whose security is based upon the algebraic problem of reducing a high degree matrix to its canonical form by similarity transformations. In this paper, we show that factoring a polynomial over a finite field can be used to break down Zheng’s public key cryptosystem. The complexity of our attack is polynomial time. In other word, t...
متن کامل2433 Long term results of the krupin eye short valve shunt
Purpose: Transscleral contect-cyclophotocoagulation has been used more end more in the treatment of therapy-refractive glaucomas, in recent years. A less pain sensation, reported by the patients, during b-eatment in comparison with cycle-cryocoagulatio was one important reason for increased usuage. The dose-effect correlation for exposure time, energy used and number of the laser impacts variou...
متن کاملAT2433-A1, AT2433-A2, AT2433-B1 and AT2433-B2 novel antitumor compounds produced by Actinomadura melliaura. II. Structure determination.
The chemical structures of AT2433-A1 (2), AT2433-A2 (3), AT2433-B1 (4) and AT2433-B2 (5) were elucidated by degradation and spectroscopic studies. Compounds 2-5 are disaccharides closely related to rebeccamycin. The aglycone in 2 and 3 was determined to be 6-N-methyl-11-chloro-5H-indolo[2,3-a]pyrolo[3,4-c]carbazole and in 4 and 5 it was determined to be 6-N-methyl-5H-indolo[2,3-a]pyrolo[3,4-c]c...
متن کاملAT2433-A1, AT2433-A2, AT2433-B1, and AT2433-B2 novel antitumor antibiotic compounds produced by Actinomadura melliaura. Taxonomy, fermentation, isolation and biological properties.
Compounds AT2433-A1 (A1), AT2433-A2 (A2), AT2433-B1 (B1), and AT2433-B2 (B2) were isolated from the cultured broth of Actinomadura melliaura sp. nov. (SCC 1655). Structurally these materials are closely related to rebeccamycin (1), an indolocarbazole antitumor antibiotic. A1, A2, B1, and B2 were active against Staphylococcus aureus A9537, Streptococcus faecalis A20688, Streptococcus faecium (AT...
متن کاملHigh Weight Loss during Radiation Treatment Changes the Prognosis in Under-/Normal Weight Nasopharyngeal Carcinoma Patients for the Worse: A Retrospective Analysis of 2433 Cases
BACKGROUND Although weight loss is common in nasopharyngeal carcinoma (NPC) patients receiving radiotherapy, the prognostic influence of weight loss and its impact modified by body mass index (BMI) are still unclear. METHODS 2433 NPC patients receiving radical radiotherapy at Sun Yat-sen University Cancer Center from November, 2000 to December, 2004 were enrolled. Weight change during radiati...
