Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. ECC allows smaller keys compared to non-EC cryptography (based on plain Galois fields ) to provide equivalent security Elliptic Curve Cryptography Definition. Elliptic Curve Cryptography (ECC) is a key-based technique for encrypting data. ECC focuses on pairs of public and private keys for decryption and encryption of web traffic. ECC is frequently discussed in the context of the Rivest-Shamir-Adleman (RSA) cryptographic algorithm Elliptic curve cryptography is used to implement public key cryptography. It was discovered by Victor Miller of IBM and Neil Koblitz of the University of Washington in the year 1985. ECC popularly used an acronym for Elliptic Curve Cryptography

1. With elliptic-curve cryptography, Alice and Bob can arrive at a shared secret by moving around an elliptic curve. Alice and Bob first agree to use the same curve and a few other parameters, and then they pick a random point G on the curve. Both Alice and Bob choose secret numbers (α, β)
2. ant RSA/DSA systems. Elliptic curves offer major advances on older systems such as increased speed, less memory and smaller key sizes. As digital signatures become more and more important in the commercial world the use of elliptic curve-based signatures will become all.
3. Elliptic curve cryptography is based on the fact that certain mathematical operations on elliptic curves are equivalent to mathematical functions on integers: Adding two points on an elliptic curve is equivalent to multiplication; Multiplying two points on an elliptic curve is equivalent to exponentiation ; These operations are the same operations used to build classical, integer-based.

Elliptic Curve Cryptography (ECC) is a newer approach, with a novelty of low key size for the user, and hard exponential time challenge for an intruder to break into the system. In ECC a 160 bits key, provides the same security as RSA 1024 bits key, thus lower computer power is required. The advantage of elliptic curve cryptosystems is the absence of subexponentia Summary. Elliptic curve cryptography (ECC) was proposed by Victor Miller and Neal Koblitz in the mid 1980s.

Elliptic Curve Encryption Elliptic curve cryptography can be used to encrypt plaintext messages, M, into ciphertexts.The plaintext message M is encoded into a point P M form the ﬁnite set of points in the elliptic group, E p(a,b).The ﬁrst step consists in choosing a generator point, G ∈ E p(a,b), such that the smallest value of n such that nG = O is a very large prime number Elliptic curve cryptography (ECC) is arguably the most efficient public-key alternative for supplying security services to constrained environments, such as the IoT. An elliptic curve group E( F q ) is defined as the set of points that satisfy the elliptic curve model E over a finite field F q , together with a point at infinity O and an additive group operation Elliptic Curve Cryptography is particularly useful in solving such problems. There are existing protocols, called key exchange protocols, which successfully do this, but not all key exchange protocols are made equal.
