Cryptography

3 November 2023 by Phillip Johnston • Last updated 29 November 2023Elliptic Curve Cryptography (ECC) is an alternative to prime-number based cryptographic algorithms like RSA. ECC is especially interesting to embedded developers due to its efficiency gains. ECC provides higher security with shorter key lengths (a 256-bit ECC key is roughly equivalent to a 3072-bit RSA key in terms of security) It requires less computational power and memory Elliptic curves are applicable for key agreement, digital signatures, and pseudo-random generators. ECC is more often used for signature generation than full-on encryption, but it can be used for such purposes by …
