Crypto Compliance Posted: 01 Mar 2018 02:08 AM PST I have a bunch of compliance requirements which are: If using elliptic curve cryptography must select a curve from the NIST standard, FIPS 186-4. When using DSA for the approved use of digital signatures must use a modulus of at least 1024 bits. Cipher suites should be configured to use SHA-2 as part of the Message Authentication Code (MAC) and Pseudo-Random Function (PRF) where possible. When using DH or ECDH for key establishment, agencies should use the ephemeral variant. How can I prove compliance/non-compliance with these? Is there a tool that can scan the network? Nessus plugins seem to provide some useful information. submitted by /u/bigBoogaChooga [link] [comments]

Designing a good S-Box Posted: 28 Feb 2018 06:28 AM PST I've been studying the S-Boxes employed by Rijndael and Camellia and I've noticed that they all follow the same structure (multiplicative inverse + affine transformation). I'm unclear on how to create a secure S-Box with this structure, because the affine transformations used in the Camellia S-Boxes seem almost random. How do I find good, secure, reversible affine transformations to use this for this purpose? submitted by /u/TheLordofNowhere [link] [comments]
