Sequential Aggregate Signatures from Trapdoor Permutations

چکیده
An aggregate signature scheme (recently proposed by Boneh, Gentry, Lynn, and Shacham) is a method for combining n signatures from n different signers on n different messages into one signature of unit length. We propose sequential aggregate signatures, in which the set of signers is ordered. The aggregate signature is computed by having each signer, in turn, add his signature to it. We show how to realize this in such a way that the size of the aggregate signature is independent of n. This makes sequential aggregate signatures a natural primitive for certificate chains, whose length can be reduced by aggregating all signatures in a chain. We give a construction in the random oracle model based on families of certified trapdoor permutations, and show how to instantiate our scheme based on RSA.

Sequential Aggregate Signatures with Lazy Verification from Trapdoor Permutations
Sequential aggregate signature schemes allow n signers, in order, to sign a message each, at a lower total cost than the cost of n individual signatures. We present a sequential aggregate signature scheme based on trapdoor permutations (e.g., RSA). Unlike prior such proposals, our scheme does not require a signer to retrieve the keys of other signers and verify the aggregate-so-far before addin...

متن کاملA Survey of Two Signature Aggregation Techniques
We survey two recent signature constructions that support signature aggregation: Given n signatures on n distinct messages from n distinct users, it is possible to aggregate all these signatures into a single signature. This single signature (and all n original messages) will convince any verifier that the n users signed the n original messages (i.e., for i 1 n user i signed message number i). ...
