Indifferentiable Hashing to Barreto–Naehrig Curves

WebIn practice, the input of a given cryptographic algorithm will be a bitstring of arbitrary length, denoted {0, 1}^*. Hence, a concern for virtually all protocols involving elliptic curves is how to convert this input into a curve point. Note that the number of points on an elliptic curve E is within 2*sqrt(p) of p by Hasse's Theorem. WebKeywords: Elliptic curve cryptography, BN curves, hashing, random oracle. 1 Introduction Many elliptic curve-based cryptographic protocols require hashing to an elliptic curve group G: they involve one or more hash functions H: {0,1}∗ → Gmapping arbitrary values to points on the elliptic curve. untitled test

WebHashing to curves. Sometimes it is useful to be able to produce a random point on an elliptic curve E p / F p corresponding to some input, in such a way that no-one will know its discrete logarithm (to any other base). This is described in detail in the Internet draft on Hashing to Elliptic Curves. WebGenerate a non-random private key. Any random 256-bit integer is suitable as private key for this curve so generating a private key is extremely fast compared to, e.g., RSA. import hashlib private_key = hashlib.sha3_256 (b"Led Zeppelin - No Quarter").hexdigest () print (private_key) This is the same as in your question.
