Web27 de out. de 2000 · As an example, we show how using an alternate characterization of a PRF could result in tighter security bounds for some types of message authentication codes. We also use this method to give a simple concrete security analysis of the counter mode of encryption.

On the Adaptive Security of MACs and PRFs — Tel Aviv University

WebIn this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. linn housing authority

Adaptive Security of Constrained PRFs

WebWe consider the security of two of the most commonly used cryptographic primitives—message authentication codes (MACs) and pseudorandom functions (PRFs)—in a multi-user setting with adaptive corruption. Whereas is it well known that any secure MAC … WebConstrained pseudorandom functions have recently been introduced independently by Boneh and Waters [Asiacrypt’13], Kiayias et al. [CCS’13], and Boyle et al. [PKC’14].
