Verifiable encryption of digital signatures and applications
- …This paper presents a new simple schemes for verifiable encryption of digital signatures. We make use of a trusted third party (TTP) but in an optimistic sense, that is, the TTP takes part in the protocol only if one user cheats or simply crashes. Our schemes can be used as primitives to build effic…

A Coalition-resistant Group Signature
- …A group signature scheme allows any member of a potentially large group to sign on behalf of the group. Group signatures are anonymous and unlinkable. Only a designated group manager can co-relate signatures and/or reveal the identity of the actual signer. At the same time, no one (including a group…

A New Approach to DNS Security (DNSSEC)
- …The Domain Name System (DNS) is a distributed database that allows convenient storing and retrieving of resource records. DNS has been extended to provide security services (DNSSEC) mainly through public-key cryptography. We propose a new approach to DNSSEC that may result in a signicantly more ecie…

Stateless-Recipient Certified E-mail System based on Verifiable Encryption
- …In this paper we present a certified e-mail system which provides fairness while making use of a TTP only in exceptional circumstances.…

Proxy Re-Signatures: New Definitions, Algorithms, and Applications
- …In 1998, Blaze, Bleumer, and Strauss (BBS) proposed proxy re-signatures, in which a semitrusted proxy acts as a translator between Alice and Bob. To translate, the proxy converts a signature from Alice into a signature from Bob on the same message. The proxy, however, does not learn any signing k…

Some Open Issues and New Directions in Group Signatures
- …Group signatures allow any member of a potentially large group to sign on behalf of the group. Group signatures are anonymous and unlinkable for everyone with the exception of a designated group manager who can co-relate signatures and reveal the identity of the actual signer. At the same time, no o…

On Traveling Incognito
- …User mobility is rapidly becoming an important and popular network feature. This is especially evident in wireless/cellular networks where user mobility raises a number of important security issues and concerns. Foremost among them is the ability to track mobile users' movements and whereabouts. Ide…

Authenticated Group Key Agreement and Friends
- …Many modern computing environments involve dynamic peer groups. Distributed simulation, multi-user games, conferencing and replicated servers are just a few examples. Given the openness of today's networks, communication among group members must be secure and, at the same time, efficient. This paper…

Improved proxy re-encryption schemes with applications to secure distributed storage
- …In 1998, Blaze, Bleumer, and Strauss proposed an application called atomic proxy re-encryption, in which a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. We predict that fast and secure re-encryption will become increasingly popu…
