Tweakable blockciphers with beyond birthday-bound security
W Landecker, T Shrimpton, RS Terashima - Annual Cryptology …, 2012 - Springer
Abstract Liskov, Rivest and Wagner formalized the tweakable blockcipher (TBC) primitive at

Strong authenticity with leakage under weak and falsifiable physical assumptions
Authenticity can be compromised by information leaked via side-channels (eg, power
consumption). Examples of attacks include direct key recoveries and attacks against the tag …

Related-key secure pseudorandom functions: The case of additive attacks
B Applebaum, E Widder - Cryptology ePrint Archive, 2014 - eprint.iacr.org
In a related-key attack (RKA) an adversary attempts to break a cryptographic primitive by
invoking the primitive with several secret keys which satisfy some known relation. The task of …
