Side Channel Resilient Variants of the Advanced Encryption Standard
Speaker: Mayank Varia, BU

Wednesday April 15, 10am, the Hariri Seminar room

Side channel attacks are the Achilles heel of the Advanced Encryption
Standard (AES): they are easier for an attacker to exploit in practice
than mathematical cryptanalysis, and they are challenging and
expensive for defenders to mitigate. This work describes a low cost
method to generate random variants of AES suited to applications that
do not require interoperability, such as local information storage.
These variants retain the security properties of AES.  The random
variation choice adds a new, independent component of the key that
improves the resilience of AES against existing power-based side
channel attacks on FPGAs and protects the user against improper key
generation, storage, and reuse. Moreover, our construction is leakage
resilient: the additional security gain degrades gracefully if some
information about our random variation choice is revealed to the

The talk will be accessible even to people without background in
