Abstract
An accumulator based on bilinear pairings was proposed at CT-RSA´05. Here, it is first demonstrated that the security model proposed by Lan Nguyen does lead to a cryptographic accumulator that is not collision resistant. Secondly, it is shown that collision-resistance can be provided by updating the adversary model appropriately. Finally, an improvement on Nguyen´s identity escrow scheme, with membership revocation based on the accumulator, by removing the trusted third party is proposed.
