In the process of Elliptic curve operation, the results of 256-bit addition and subtraction are often outside the interval [0,p], and the operation of +p or-p is required. The 256-bit NIST domain Elliptic curve parameter p is generated in the following formula: p = 2^256?2^224 + 2^192 + 2^96? 1 The formula is broken down by the symbol: p = (2^256 + 2^192 + 2^96)-(2^224 + 1) Convert to 16 and press the 64-bit section to change to the following form: +:
This is the generation formula for the 256-bit NIST prime-domain elliptic curve primes p:p256 = (2 ^ 256)?(2 ^ 224) + (2 ^ 192) + (2 ^ 96)? 1The 64-bit section breaks it down into an addition vector as follows:1 0000000000000001 0000000000000000 0000000100000000 0000000000000000-0000000100000000 0000000000000000 0000000000000000 0000000000000001= ffffffff00000001 0000000000000000 00000000ffffffff ffffffffffffffffHaving a positive integer n, whose valu

A glance at the headline will reveal that data leaks are now becoming a common problem. Many of these accidents involve litigation, financial losses, and public relations issues that the Organization is responsible for. Being able to explain the changes that are occurring o
2 We find that useful lattices are not many, and after a detailed discussion of the classifications, only these squares are useful: Four angles, as well as obstacles (or deceleration zone) itself and the upper and lower left and right four directions, as well as the obstacles in the row (and ±1) of the tail two. Then we just have to sort all the obstacles and deceleration bands by X-Y and y-x, for each useful lattice two points to find left and right will push to where, even the end of the viol
