Hi there, do you plan to implement signatures aggregation?
It would be an useful feature. Signature aggregation allows to combine different signatures into a single one. The receiver, will be able to verify the validity of each signature by analyzing just the aggregate. There are different methods to implement signatures aggregation, and it is also possible to use standard RSA cryptography. An excerpt from http://www.ics.uci.edu/~gts/paps/nt-2006.pdf : Given t different messages {m_1, ..., m_t } and their corresponding signatures {d_1, ..., d_t } generated by the same signer, a Condensed-RSA signature is computed as the product of all t individual signatures: d_{1,t} = \prod_{i=1}^t d_i (mod n) The resulting aggregated (or condensed) signature d_{1,t} is of the same size as a single standard RSA signature. Verifying an aggregated signature requires the verifier to multiply the hashes of all t messages and checking that: ( d_{1,t} )^e == \prod_{i=1}^t h(m_i) (mod n) For more informations: http://crypto.stanford.edu/~dabo/abstracts/aggsurvey.html http://crypto.stanford.edu/~dabo/abstracts/aggreg.html Best regards, 0; -- :wq!
