The book tells (well, hints) how to compute lambda and beta, and here are the values I found:
lambda = 0x5363ad4cc05c30e0a5261c028812645a122e22ea20816678df02967c1b23bd72
beta = 0x7ae96a2b657c07106e64479eac3434e99cf0497512f58995c1396c28719501ee
Isn't lambda a solution of l*l+l=-1 mod n ?
If that's the case, there are actually two possible lambdas:
5363AD4CC05C30E0A5261C028812645A122E22EA20816678DF02967C1B23BD72
and
AC9C52B33FA3CF1F5AD9E3FD77ED9BA4A880B9FC8EC739C2E0CFC810B51283CE
What made you choose the smaller one ?
