36 The CPG library is delivered with the openais project. This library is used
37 to create distributed applications that operate properly during partitions, merges,
40 The library provides a mechanism to:
41 * handle abstraction for multiple instances of an CPG library in one application
42 * join one or more groups
43 * leave one or more groups
44 * Deliver messages to members of that group
45 * Deliver configuration changes
48 The CPG library encrypts all messages sent over the network using the SOBER-128
49 stream cipher. The EVS library uses HMAC and SHA1 to authenticate all messages.
50 The CPG library uses SOBER-128 as a pseudo random number generator. TheCPG
51 library feeds the PRNG using the /dev/random Linux device.
53 This software is not yet production, so there may still be some bugs.
