Keywords:
Identification via channels, identification function, complexity of distributive computing, one/two-way probabilistic communications

Description

Identification problem (Ahlswede and Dueck, 1989) over the Binary Symmetric Channel (BSC) is linked to the communication complexity problem (one/two way communications) and interpreted in that context.

Identification Codes via Prime Numbers

Keywords:
Identification via channels, Prime Number Encryption

Short Description:
An approach for construction of identification codes for noiseless channel by means of the prime number encryption would be studied.

Description

In original scheme of identificaion via channels (Ahlswede and Dueck, 1989), a non-constructive method for coding for noiseless channel was studied. To address the explicit construction of identificaion codes, foremost Ahlswede and Verboven, 1991 provide a number theoretic approach based on the two successive prime number encryption. This method require the knowledge of first 2^n prime numbers for a block-length of n codeword. In this research internship, this method along with related prime number encryption tools and theorems would be investigated. Further, the extension of this scheme to a general DMC will be analyzed.

Prerequisites

Basics of:

information/identification theory
channel coding
prime number theorem (Chebyshev)

On the Equivalence of Identification and Authentication

On the Equivalence of Identification and Authentication

Keywords:
Identification via channel, identification codes, authentication, authentication codes

Short Description:
A Certain equivalence of identification and authentication would be shown.

Description

It would be shown that under suitable formulations (preserving all salient features) the two problem of Identification (Ahlswede and Dueck, 1989) and Authentication (Simmons, G. J. 1984) are in essence very close to each other. This equivalency was conjectured first by M. S. Pinsker. In this research internship the student is expected to address this conjecture. Both problems must be studied separately and then the similar essence of them should be drawn out. In particular the identification codes and authentication codes along with theire relation will be investigated.

Prerequisites

Background in Information Theory and Channel Coding
Familiarity with fundamentals of Identification Theory
