On the Round Security of Symmetric-Key Cryptographic Primitives
We put forward a new model for understanding the security of symmetric-key primitives, such as block ciphers. The model captures the fact that many such primitives often consist of...

Pseudo-random functions and parallelizable modes of operations of a block cipher
This paper considers the construction and analysis of pseudo-random functions (PRFs) with specific reference to modes of operations of a block cipher. In the context of message aut...
