and Victor S. Miller (IBM) in 1985. Although the ECC algorithm was proposed for cryptography in 1985, it has had a slow start and it took nearly twenty years, until 2004 and 2005, for the scheme to gain wide acceptance. ECC (Elliptic Curve Cryptography...

The use of elliptic curves in cryptography was suggested by both Neal Koblitz and Victor S. Miller independently in 1985; ECC algorithms entered common use in 2004. The advantage of the ECC algorithm over RSA is that the key can be smaller, resulting in improved speed and security. The disad...
But what if p is not 3 modulo 4? Well, then one way to solve the problem is by application of the Tonelli–Shanks algorithm, which you can find on Wikipedia and which is also quite straightforward. 2 Elliptic Curve Cryptography2.1 IntroductionIf you're first getting started with ECC, ...
