Post-Quantum Public-key Encryption
SPEAKER: Dr Amin Sakzad,
Date: Friday 31st August
Time: 3:00pm–4:00pm (Talk & Q/A)
Venue: Building 8 Level 9 Room 66 (AGR)
RMIT City campus
The seminar will be followed by snacks and drinks
All students, staff and visitors are welcome
ABSTRACT: In a seminar in March Dr Sakzad introduced Titanium-CPA, a practical and optimised public-key encryption scheme based on the MP-LWE problem, building on the theoretical results reported in [RSSS17] that exploit the associativity property of the middle product. The Titanium cryptosystem was presented at the Workshop on Cybersecurity in a Post-Quantum World, hosted by NIST in April.
In this presentation Dr Sakzad will detail the constant-time implementation of Titanium as both a Public key system, and a Key Encapsulation Mechanism. Titanium is secure under adaptive chosen-ciphertext attacks (i.e. IND-CCA secure), assuming the classical random oracle model for the underlying hash functions.
