From: A secure cross-domain authentication scheme based on threshold signature for MEC
Symbol | Definition |
|---|---|
E | Exponential operation in \(\mathbb {G}\) |
P | Bilinear pairing operation |
n | Number of signature nodes |
t | Size of threshold |
\(\left| \mathbb {G} \right|\) | Bit length of the element in \(\mathbb {G}\) |
\(\left| {{\mathbb {Z}}_{p}} \right|\) | Bit length of the element in \({{\mathbb {Z}}_{p}}\) |
\(\left| m \right|\) | Bit length of the authentication message m |
