Abstract
A digital signature over a message may be compressed by determining a plurality of values based at least in part on the message. A mapping of the plurality of values over a digital signature scheme may be used to determine a value from which a portion of the compressed digital signature is decompressible by cryptographically deriving one or more components of the uncompressed digital signature. A public key may be used to verify the authenticity of the compressed digital signature and message.
