Aggregate Message Authentication Codes
We propose and investigate the notion of aggregate message authentication codes (MACs) which have the property that multiple MAC tags, computed by (possibly) different senders on multiple (possibly different) messages, can be aggregated into a shorter tag that can still be verified by a recipient who shares a distinct key with each sender. We suggest aggregate MACs as an appropriate tool for au...
متن کاملNon-Adaptive Group Testing Framework based on Concatenation Code
We consider an efficiently decodable non-adaptive group testing (NAGT) problem that meets theoretical bounds. The problem is to find a few specific items (at most d) satisfying certain characteristics in a colossal number of N items as quickly as possible. Those d specific items are called defective items. The idea of NAGT is to pool a group of items, which is called a test, then run a test on ...
متن کاملLecture 9: Message Authentication Code
In this lecture, we will study message authentication. This lecture is organized as follows. • First we will review the cryptographic algorithms that we have learned so far, and discuss their limitations in protecting data integrity and supporting message authentication. • Then we will examine the concept and the design of Message Authentication Code (MAC). I. REVIEW In the previous lectures, w...

متن کاملGroup Message Authentication
Group signatures is a powerful primitive with many practical applications, allowing a group of parties to share a signature functionality, while protecting the anonymity of the signer. However, despite intensive research in the past years, there is still no fully satisfactory implementation of group signatures in the plain model. The schemes proposed so far are either too inefficient to be used...
