Digital Signatures emerge naturally from Public-Key Encryption based on trapdoor permutations, and the "duality" of the two primitives was noted as early as Diffie-Hellman's seminal work. The present work is centered around the crucial observation that two well known cryptographic primitives whose connection has not been noticed so far in the literature enjoy an analogous "duality." The primitives are Group Signature Schemes and Public-Key Traitor Tracing. Based on the observed "duality," wedoi:10.1007/3-540-39200-9_39 fatcat:aqtbceuxvnekjl4l3yqfmdj4ye
