YU Wei-chi, HE Da-ke · Jisuanji yingyong yanjiu · 2006
The conceptions of PPKC and IPKC are introduced in this paper.Secure performances of PPKC and IPKC under different attacks are contrasted.A new type of attacks,Errors Sniffing Attacks(ESA) which work on IPKC only,are presented.Because NTRU is a typical IPKC,its performance of ESA resistance should be studied.Based on NTRU decryption(failures,) an ESA algorithm can explore partial even whole information of private key f.In order to keep NTRU away from ESA,some suggestions are given at the end of this paper.
