Term

dual signature

A single digital signature that protects two separate messages by including the hash results for both sets in a single encrypted value. [SET2]

Senses

(O) /SET/

A single digital signature that protects two separate messages by including the hash results for both sets in a single encrypted value. [SET2]

Deprecated Usage: IDOCs SHOULD NOT use this term except when qualified as "SET(trademark) dual signature" with this definition.

Tutorial: Generated by hashing each message separately, concatenating the two hash results, and then hashing that value and encrypting the result with the signer's private key. Done to reduce the number of encryption operations and to enable verification of data integrity without complete disclosure of the data.
