Abstract. Chosen-message attack on RSA is usually considered as an inherent property of its homomorphic structure. In this paper, we show that nonhomomorphic RSA-type cryptosystems...

We present a new type of fault attacks on elliptic curve scalar multiplications: Sign Change Attacks. These attacks exploit different number representations as they are often emplo...
The isogeny for elliptic curve cryptosystems was initially used for the efficient improvement of order counting methods. Recently, Smart proposed the countermeasure using isogeny f...
