| Abstract(in English) | Hastad showed that low exponent RSA is not secure if the same message is encrypted to several receivers.This is true even if time-stamp is used for each receiver.For example,let e=3.Then if the number of receivers=7,the eavesdropper can find the plaintext from the seven ciphertexts of each receiver. This paper shows that elliptic curve RSA is not secure in the same scinario.It is shown that Koyama′s scheme and Demytko′s sche me are not secure if e=3 Demytko′s scheme,e can take the value of 2.In this case,this syste m is not secure if the number of receiver=11. |
