GROUP SIGNATURES WITH PROBABILISTIC REVOCATION

摘要

Aspects of group signatures with probabilistic revocation are described. In one example employing these aspects, at least one computing device can map an alias token to an alias code comprising a plurality of alias code segments. Each of the alias code segments is based at least in part on a set of orthogonal codes. Also, each of the alias code segments corresponds to a segment of the alias token. A revocation code is based at least in part on a plurality of revoked alias codes. One of the alias code segments and a corresponding segment of the revocation code can be utilized to determine a revocation status of the alias token.
