Silaghi, Ph.D. Elliptic Curve Cryptography (ECC) has positioned itself as one of the most promising candidates for various applications since its introduction by Miller and Kolbitz in 1985 [53, 44]. The core operation for ECC is the scalar multiplication [k]P where many efforts have addressed its computation speed. -

Rational space curves through a given set of points It is a classical result of enumerative geometry that there is precisely one twisted cubic through a set of six points in general position in P3. Several proofs are available in the literature; see, for example [15, §11, Exercise 4; or 12, p. 186, Example 11]. The present paper is devoted to the generalization of this result to rational curves of higher degrees. < Let m be a positive integer; we denote by €m the Chow variety of all curves with ( degree m in PQ. As is well-known (cf. Lemma 2.4), €m has an irreducible component 0im, of dimension Am, whose general element is the Chow point of a smooth rational curve. Moreover, the Chow point of any irreducible space curve with degree m and geometric genus zero belongs to 0tm. Except for m = 1 or 2, very little is known on the geometry of this variety. So we may also say that the object of this paper is to undertake an enumerative study of the variety $%m. -

Minerva: the Curse of ECDSA Nonces Systematic Analysis of Lattice Attacks on Noisy Leakage of Bit-Length of ECDSA Nonces
Minerva: The curse of ECDSA nonces Systematic analysis of lattice attacks on noisy leakage of bit-length of ECDSA nonces Ján Jančár1, Vladimír Sedláček12, Petr Švenda1 and Marek Sýs1 1 Masaryk University, 2 Ca’ Foscari University of Venice {j08ny,vlada.sedlacek}@mail.muni.cz;{svenda,syso}@fi.muni.cz Abstract. We present our discovery1 of a group of side-channel vulnerabilities in imple- mentations of the ECDSA signature algorithm in a widely used Atmel AT90SC FIPS 140-2 certified smartcard chip and five cryptographic libraries (libgcrypt, wolfSSL, MatrixSSL, SunEC/OpenJDK/Oracle JDK, Crypto++). Vulnerable implementations leak the bit-length of the scalar used in scalar multiplication via timing. Using leaked bit-length, we mount a lattice attack on a 256-bit curve, after observing enough signing operations. We propose two new methods to recover the full private key requiring just 500 signatures for simulated leakage data, 1200 for real cryptographic library data, and 2100 for smartcard data. The number of signatures needed for a successful attack depends on the chosen method and its parameters as well as on the noise profile, influenced by the type of leakage and used computation platform. We use the set of vulnerabilities reported in this paper, together with the recently published TPM-FAIL vulnerability [MSE+20] as a basis for real-world benchmark datasets to systematically compare our newly proposed methods and all previously published applicable lattice-based key recovery methods. The resulting exhaustive comparison highlights the methods’ sensitivity to its proper parametrization and demonstrates that our methods are more efficient in most cases. For the TPM-FAIL dataset, we decreased the number of required signatures from approximately 40000 to mere 900. -

Abstract Elliptic curve cryptography is a public key cryptography which contains two different keys for encryption and decryption. The points on elliptic curves are represented in affine coordinates, the arithmetic on elliptic curves contain the expensive inverse operation in modular arithmetic, which increases the computation time, memory etc. Hence to avoid the inverse operation the points are represented in projective coordinate system. In this paper the different projective coordinates for different elliptic curves are derived and the number of operations for point addition in EC arithmetic are compared. Keywords: Elliptic curves, Projective coordinates, Affine coordinates, Point addition,Point doubling 1 Introduction Elliptic curves finds application in wide areas of mathematics, they are applied in various fields from cryptography to mathematical physics. Elliptic curves 2236 M. Lavanya and V. Natarajan with points in finite field are called finite groups. Elliptic curve cryptography (ECC) is a public key cryptographic system. It is based on the algebraic structure of elliptic curves over finite fields. Elliptic curve cryptography was proposed by Miller and Koblitz in 1980's. -
