发明名称 Method and system for generating a signature
摘要 <p>The process for generation of an electronic signature includes calculation of an exponential, A = Bh (5). The value of A is calculated according to the this equation, with h being a 78-digit decimal number. The process for generation of an electronic signature includes application of an SFLASH algorithm. The message which is to be electronically signed is subject to a series of transformations. These include three applications of chopping functions (1,2,3), and application of a refining transformation (t-1) (4). There is a further calculation of an exponential, A = Bh (5) followed by the application of a further refining transformation (s-1) (6). The process is such that the value of A is calculated according to the equation A = Bh, with h being a 78-digit decimal number.</p>
