iCIS Group Talk - A Bloom Filter Based One Time Signature

Date & Time:
September 30, 2016 | 1:00 pm - 2:00 pm

Masoumeh Shafieinejad

The iCORE Information Security Lab (iCIS) is hosting a Group Talk.

Masoumeh Shafieinejad, PhD candidate and ISPIA and iCIS member, will be presenting.


One-time signature (OTS) schemes are important cryptographic primitives that can be constructed using one-way functions, and provide post-quantum security unlike many widely used signature schemes which are based on hardness of factorization or discrete logarithm problems. In this this talk I will explain the idea of using Bloom Filters as the one way function in an OTS, in combination with 1-Cover Free Families in order to sign as many messages as possible. I will demonstrate the security and performance evaluation of the scheme and the challenges I face.
