cryptography - Is there a standard for threshold (m out of n) cryptosystems? -


i'd use m out of n cryptosystem storing sensitive data (2 out of 3 exact). i've learned wikipedia it's called threshold cryptosystem, haven't found practical implementations.

for regular public key cryptography have standards pem , implementations openssl ready use. there similar m out of n cryptography? avoid having invent own ways store (serialize) keys , encrypt them password. of trivial use openssl. , worst thing relying on homebrew implementation of crypto algorithm.

i'm interested in python libraries, i'd hear if there standard , implementation in language.

well, it's homebrew implementation, think it's pretty good. , it's in python. take @ http://programmingpraxis.com/2011/06/17/adi-shamirs-threshold-scheme/.

for class project i'm attempting write vst plugin backed cuda. current cuda workflow on linux box, i'd prefer compile , link there. according wikipedia , should possible (i couldn't find steinberg documentation relevant linux) can't find makefile or instructions on how build if aren't using xcode or visual studio. i'm vst 3 sdk doesn't support linux. when try compile plugin under linux, error: ./base/source/fatomic.cpp:39:30: fatal error: libkern/osatomic.h: no such file or directory this issue caused following code in "vst3 sdk/base/source/fatomic.cpp" #if mac #include <libkern/osatomic.h> #if mac_os_x_version_min_required > mac_os_x_version_10_4 #define native_atomic_type (volatile int32_t*) #else #define native_atomic_type (int32_t*) #endif #elif windows #include <windows.h> #endif but hope compiling under linux work vst sdk 2.4. reading. jvstwrapper seems run on lin...
