Stronger security per bit

Definition

Stronger security per bit refers to the increased level of security provided by cryptographic systems for each individual bit of key or data. In the context of cryptographic algorithms, this concept emphasizes how certain systems, particularly elliptic curve cryptosystems, can offer enhanced security with shorter key lengths compared to traditional systems. This means that even a small key size in elliptic curve cryptography can provide a high degree of security against potential attacks.
