secp256k1 was almost never used before Bitcoin became popular, but it is now gaining in popularity due to its several nice properties. Most commonly-used curves have a random structure, but secp256k1 was constructed in a special non-random way which allows for especially efficient computation Authenticated secp256k1 ECDH with Python. Authenticated secp256k1 ECDH. Elliptic Curve Diffie Hellman using secp256k1 with Python, and where we use a long-term key for Bob and Alice to create a shared session key. The secp256k1 curve is in the Weierstrass curve form (y²=x³+ax+b) Bitcoin uses the Elliptic Curve Digital Signature Algorithm (ECDSA) based on elliptic curve cryptography.The particular elliptic curve is known as secp256k1, which is the curve. y² = x³ + 7. over a finite field (a.k.a. Galois field) to be described shortly.. Addition on elliptic curves in the plane is defined geometrically in terms of where lines intercept the curve A few days ago I blogged about the elliptic curve **secp256k1** and its use in Bitcoin. This curve has a sibling, secp256r1.Note the r in the penultimate position rather than a k. Both are defined in SEC 2: Recommended Elliptic Curve Domain Parameters.Both are elliptic curves over a field z p where p is a 256-bit prime (though different primes for each curve) Actually secp256k1 is defined over a Galois field, not a ring of integers modulo a prime. Now, it turns out that the secp256k1 field is a prime field and therefore isomorphic to a ring of integers modulo a prime, but this is not true for all ECDSA curves -- in fact, the sectXXXyZ curves (for which much faster hardware exists than the secpXXXyZ curves) cannot be described using rings of.

Secp256k1 kommer från den öppna standarden SEC2 (läs även här). När någon ska överföra BitCoins till en annan person så används ECDSA: Alice signerar transaktionen med sin privata nyckel och publicerar denna signatur för andra på Bitcoin-nätverket att kontrollera med sin publika nyckel. Dock så. Security secp256k1 = $\log_2\sqrt{\frac{{\pi}n_{secp256k1}}{12}}=127.03$ Which are comparable. Then, considering rigidity, secp256k1 is more rigid than secp256r1. So it is theoretically possible that secp256r1 was chosen to belong to a secret class of elliptic curves that are not as secure as we think secp256k1 2.4.1 128 256 3072 k secp256r1 2.4.2 128 256 3072 r secp384r1 2.5.1 192 384 7680 r secp521r1 2.6.1 256 521 15360 r Table 1: Properties of Recommended Elliptic Curve Domain Parameters over F p The recommended elliptic curve domain parameters over F p have been given nicknames to enable them to be easily identiﬁed Elliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners. It is dependent on the curve order and hash function used. For bitcoin these are Secp256k1 and SHA256(SHA256()) respectively.. A few concepts related to ECDSA * Replace secp256k1 in the above with whichever curve you are interested in*. Keys can be generated from the ecparam command, either through a pre-existing parameters file or directly by selecting the name of the curve. To generate a private/public key pair from a pre-eixsting parameters file use the following

Bitcoin Trust System vs Centralised Trust Systems Bitcoin fundamentally inverts the trust mechanism of a distributed system secp256k1 ECDSA signing/verification and key generation. Additive and multiplicative tweaking of secret/public keys. Serialization/parsing of secret keys, public keys, signatures. Constant time, constant memory access signing and public key generation. Derandomized ECDSA (via RFC6979 or with a caller provided function.) Very efficient. For the secp256k1 curve, the private key is 256-bit integer (32 bytes) and the compressed public key is 257-bit integer (~ 33 bytes). ECDSA Sign. The ECDSA signing algorithm (RFC 6979) takes as input a message msg + a private key privKey and produces as output a signature, which consists of pair of integers {r, s} secp256k1 has characteristic p, it is defined over the prime field ℤ p. Some other curves in common use have characteristic 2, and are defined over a binary Galois field GF(2 n), but secp256k1 is not one of them. As the a constant is zero, the ax term in the curve equation is always zero, hence the curve equation becomes y 2 = x 3 + 7

Functions. Program executes scalar multiplication on a provided point, G (input) and a provided 256-bit randomly generated private-key, d (input). The program defaults to the secp256k1 base point. Inputs should be in big-endian hexidecimal. Program has only been tested on a few points using a variety of private-keys So I thought to try halving the secp256k1 generator. Unfortunately, the constant is 166 bits long-- too long to be a sha1 output alone! I found that several other curves use the same constant (224k1 and the 160k1, IIRC)

** The issue is why Satoshi chose to use the elliptic curve known as secp256k1 as the basis for the elliptic curve digital signature algorithm (ECDSA) proving ownership of coin in BTC, and why I chose to use a different curve (prime256v1 aka X9_62_prime256v1 aka P256)**.

* The elliptic curve C is the secp256k1 curve*. EC crypto is based on modular arithmetic. In this overwhelming context, our only input is the private key. The public key is uniquely derived from the private key, be it uncompressed or compressed. First, we'll use OpenSSL to generate a sample keypair from the command line ECC crypto algorithms can use different underlying elliptic curves.Different curves provide different level of security (cryptographic strength), different performance (speed) and different key length, and also may involve different algorithms..

More specifically, it uses one particular curve called secp256k1. Now, this curve has an order of 256 bits, takes 256 bits as input, and outputs 256-bit integers. And 256 bits is exactly 32 bytes.
