2. On the security of mix-nets and hierarchical group signatures
Sammanfattning : In this thesis we investigate two separate cryptographic notions: mix-nets and hierarchical group signatures. The former notion was introduced by Chaum (1981). The latter notion is introduced in this thesis, but it generalizes the notion of group signatures which was introduced by Chaum and Heyst (1991). LÄS MER
3. Some aspects of cryptographic protocols : with applications in electronic voting and digital watermarking
