چکیده

We evaluate the security of the recently proposed authenticated encryption scheme POET with regard to weak keys when its universal hash functions are instantiated with finite field multiplications. We give explicit constructions for weak key classes not covered by POET’s weak key testing strategy, and demonstrate how to leverage them to obtain universal forgeries.

Twisted Polynomials and Forgery Attacks on GCM

Polynomial hashing as an instantiation of universal hashing is a widely employed method for the construction of MACs and authenticated encryption (AE) schemes, the ubiquitous GCM being a prominent example. It is also used in recent AE proposals within the CAESAR competition which aim at providing nonce misuse resistance, such as POET. The algebraic structure of polynomial hashing has given rise...

Comb to Pipeline: Fast Software Encryption Revisited

AES-NI, or Advanced Encryption Standard New Instructions, is an extension of the x86 architecture proposed by Intel in 2008. With a pipelined implementation utilizing AES-NI, parallelizable modes such as AES-CTR become extremely efficient. However, out of the four non-trivial NIST-recommended encryption modes, three are inherently sequential: CBC, CFB, and OFB. This inhibits the advantage of us...

Effects of Weak Layer Angle and Thickness on the Stability of Rock Slopes

This paper researches two key factors (angle and thickness) of a weak layer in relation to their influencing mechanism on slope stability. It puts forward the sliding surface angle and morphological model criteria for the control of rock slopes and realization of its failure mechanism. By comparing the Failure Modes and Safety Factors (Fs) obtained from numerical analysis, the influence pattern...

Critique of Research Book (Literature)/ Which Hafiz? An Overview of Hafiz and Russian Poets: Alireza Anoshirvani

Abstract One of the broad areas of research in traditional comparative literature is the study of the influence of one poet on another in a different culture. Almost all literary influences occur through translation. The translator is a mediator between the two poets, and any study of literary influences in the realm of comparative literature would be irrelevant if the role of the translator a...
