Performances of Cryptographic Accumulators
International audienceCryptographic accumulators are space/time efficient data structures used to verify if a value belongs to a set. They have found many applications in networking and distributed systems since their in- troduction by Benaloh and de Mare in 1993. Despite this popularity, there is currently no performance evaluation of the different existing de- signs. Symmetric and asymmetric accumulators are used likewise without any particular argument to support either of the design. We aim to es- tablish the speed of each design and their application's domains in terms of their size and the size of the values
Tunable Security for Deployable Data Outsourcing
Security mechanisms like encryption negatively affect other software quality characteristics like efficiency. To cope with such trade-offs, it is preferable to build approaches that allow to tune the trade-offs after the implementation and design phase. This book introduces a methodology that can be used to build such tunable approaches. The book shows how the proposed methodology can be applied in the domains of database outsourcing, identity management, and credential management
Performance analysis of accumulator-based revocation mechanisms
Anonymous credentials are discussed as a privacy friendlier replacement for public key certificates. While such a transition would help to protect the privacy of digital citizens in the emerging information society, the wide
scale deployment of anonymous credentials still poses many challenges. One of the open technical issues is the efficient revocation of anonymous credentials. Currently, accumulator based revocation is considered to be the
most efficient and most privacy friendly mechanism for revoking anonymous credentials. This paper analyses the performance of three accumulator based credential revocation schemes. It identifies the bottlenecks of those
implementations and presents guidelines to improve the efficiency in concrete applications.status: publishe
