Andrew Wang commented on HADOOP-10734: -------------------------------------- I think the OpenSSL mode that Yi's patch added is FIPS compliant. Wikipedia says that RdRand meets "standards such as NIST SP 800-90A,[4] FIPS 140-2, and ANSI X9.82.[2]", so users who care can enable that. At the same time, it seems like others would like to use /dev/urandom, and this patch also allows that. Mike, does this work for you? I think we could also commit what's here right now, and re-examine FIPS compliance if necessary in a follow-on JIRA. > Implementation of true secure random with high performance using hardware > random number generator. > -------------------------------------------------------------------------------------------------- > > Key: HADOOP-10734 > URL: https://issues.apache.org/jira/browse/HADOOP-10734 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Affects Versions: fs-encryption (HADOOP-10150 and HDFS-6134) > Reporter: Yi Liu > Assignee: Yi Liu > Fix For: fs-encryption (HADOOP-10150 and HDFS-6134) > > Attachments: HADOOP-10734-fs-enc.004.patch, HADOOP-10734.1.patch, > HADOOP-10734.2.patch, HADOOP-10734.3.patch, HADOOP-10734.4.patch, > HADOOP-10734.patch > > > This JIRA is to implement Secure random using JNI to OpenSSL, and > implementation should be thread-safe. > Utilize RdRand to return random numbers from hardware random number > generator.
