A simple new technique of parallelizing methods for solving search problems which seek
collisions in pseudorandom walks is presented. This technique can be adapted to a wide …

In many real-world applications, sensitive information must be kept it log files on an
untrusted machine. In the event that an attacker captures this machine, we would like to …

This paper describes the state of the art for cryptographic primitives that are used for
protecting the authenticity of information: cryptographic hash functions and digital signature …

Foreword by Lars Knudsen Practical Intranet Security focuses on the various ways in which
an intranet can be violated and gives a thorough review of the technologies that can be used …

The security of iterated message authentication code (MAC) algorithms is considered, and in
particular, those constructed from unkeyed hash functions. A new MAC forgery attack …

This paper compares the parameters sizes and software performance of several recent
constructions for universal hash functions: bucket hashing, polynomial hashing, Toeplitz …

This paper examines proposals for three cryptographic primitives: block ciphers, stream
ciphers, and hash functions. It provides an overview of the design principles of a large …

Because of the increasing importance of the international business and communication, it
has become necessary to forward signed documents to a long distance. Traditional mail …

With the increasing number of MBone sessions the interest of home users to participate in
multicast sessions is also increasing. Unfortunately the cost for the hardware necessary to …

In this paper, four new algorithms for improvements of MD5 and SHA-Keyed/Unkeyed MD5
and Keyed/Unkeyed SHA are proposed. We change the mode of fixed retrieval of the …
