    obfusc

    toolchain for obfuscated compilation

    This is a C compiler, assembler, linker and virtual machine for computing based on encrypted working and obfuscated compilation and execution. The idea is that the platform machine `works encrypted' for the user and unencrypted for the operator, running a machine code instruction set in user mode that is provably safe against computational attacks, for code that is generated by a compiler that has introduced random variations into the code at each recompilation so that the attacker has no statistical leverage from human programming biases.

    ExRandom

    Sampling exactly from the normal and exponential distributions

    ExRandom is a small header-only C++11 library for exact sampling from the normal, exponential, and discrete normal distributions (provided that the underlying generator is perfect). This library provides an implementation of the algorithms described in C. F. F. Karney, Sampling exactly from the normal distribution, ACM Trans. Math. Software 42(1), 3:1-14 (Jan. 2016), https://doi.org/10.1145/2710016, https://arxiv.org/abs/1303.6257.
