....type II hash defined by H(r) r mod q. PVSSR scheme (Pintsov Vanstone Signature Scheme with message Recovery [31] is defined on a prime order elliptic curve subgroup with a slight variant of Schnorr category (where replaces h) PVSSR projection and type II hash. Naccache Stern scheme [24] is defined on a prime order elliptic curve subgroup with ElGamal category, NS projection based on ECxq projection and type I hash. Abe Okamoto scheme [1] is a scheme with total message recovery: no variable m. It is defined on a prime order elliptic curve subgroup with Schnorr category, the ....

....in the signature. For example, product registration systems often ask users to key in a signature provided on a CD label. More generally, short signatures are needed in low bandwidth communication environments. For example, short signatures are needed when printing a signature on a postage stamp [21, 19]. Currently, the two most frequently used signatures schemes, RSA and DSA, provide relatively long signatures compared to the security they provide. For example, when one uses a 1024 bit modulus, RSA signatures are 1024 bits long. Similarly, when one uses a 1024 bit modulus, standard DSA ....
....size 151 bits. In Section 3.5 we outline an approach for generalizing our technique and building signatures of any length. Constructing short signatures is an old problem. Several proposals show how to shorten the DSA signature scheme while preserving the same level of security. Naccache and Stern [19] propose a variant of DSA where the signature length is approximately 240 bits. Mironov [18] suggests a DSA variant with a similar length and gives a concrete security analysis of the construction (in the random oracle model) Another technique proposed for reducing the DSA signature length is ....
