Unlinkable serial transactions: protocols and applications
Stuart G. Stubblebine, Paul F. Syverson, David M. Goldschlag
Pages: 354-389
DOI: 10.1145/330382.330384
We present a protocol for unlinkable serial transactions suitable for a variety of network-based subscription services. It is the first protocol to use cryptographic blinding to enable subscription services. The protocol prevents the service...

On secure and pseudonymous client-relationships with multiple servers
Eran Gabber, Phillip B. Gibbons, David M. Kristol, Yossi Matias, Alain Mayer
Pages: 390-415
DOI: 10.1145/330382.330386
This paper introduces a cryptographic engine, Janus, which assists clients in establishing and maintaining secure and pseudonymous relationships with multiple servers. The setting is such that clients reside on a particular subnet (e.g.,...

Strength of two data encryption standard implementations under timing attacks
Alejandro Hevia, Marcos Kiwi
Pages: 416-437
DOI: 10.1145/330382.330390
We study the vulnerability of two implementations of the Data Encryption Standard (DES) cryptosystem under a timing attack. A timing attack is a method, recently proposed by Paul Kocher, that is designed to break cryptographic systems. It...
