Notes - Computer Security MT24, Elliptic curve cryptography
Flashcards
@Define an elliptic curve.
An equation of the form
\[y^2 = x^3 + ax + b\]What is the basic idea behind elliptic curve cryptography?
Rather than considering the discrete logarithm and factorisation over the integers, instead use an elliptic curve group consisting of solutions to
\[y^2 = x^3 + ax + b \pmod{n}\]and a corresponding group operation.
Show where the product $p \otimes q$ would be on this diagram:
