Table 1 Parameter description

From: Data processing scheme based on blockchain

Parameter Description
\(\lambda_{p}\) Discrete logarithmic secure parameter (1024 bit)
\(\lambda_{q}\) Discrete logarithmic secure parameter (257 bit)
\(p\) Random prime number \(\left| p \right| = \lambda_{p}\)
\(q\) Random prime number \(q|p - 1,\left| q \right| = \lambda_{q}\)
\(\beta\) Data block size (16 kB)
\(m\) Number of subblocks contained in each block \(m = \left\lceil {\frac{\beta }{{\lambda_{q} - 1}}} \right\rceil \left( {512bit} \right)\)
\(g\) Generate the \(1 \times m\) row vector, randomly selected from the \({\mathbb{Z}}_{p}\)
\({\mathbb{G}}\) Hash parameters, including \({\mathbb{G}} = \left( {p,q,g} \right)\)
\(n\) Block number
Seed Seed of keystream generator
MAXRAND Maximum possible output of \(rand( \cdot )\)
MINRAND Minimum possible output of \(rand( \cdot )\)
