Crypto Test Vectors

This directory contains test vectors for the following functions as specified here.

Additionally there are test vectors for crypto functions needed for encryption and signing/verification.

All python scripts implement the corresponding functionality in order to depict the mathematical and cryptographic calculations involved.

Linkage Values lv(i,j)

• lv.txt: test vectors for i = {0,1} and j randomly chosen in [1,20]
• lv.py : Python script that generates the test vectors

Group Linkage Values glv(i,j,k) and Encrypted Indices ei(j,k)

• glv.txt: test vectors for i = {0,1} and j randomly chosen 32-bit value
• glv.py : Python script that generates the test vectors

Butterfly Expansion Function

• bfkeyexp.txt: test vectors for Butterfly Expansion Function for Certificate and Encryption key pairs
• bfkeyexp.py : Python script that generates the test vectors
