Digital Signature with Message Recovery and Authenticated Encryption (Signcryption)-A Comparison
TLDR
It is shown that there are major differences between a digital signature scheme with message recovery and authenticated encryption scheme by proposing a digital signatures withmessage recovery scheme and signcryption scheme as an example for comparison.Abstract:
Mitchell and Yeun [8] showed that Chen’s scheme [2] is not a digital signature scheme with message recovery, whereas it should be called an authenticated encryption scheme. Also note that similar remarks have been made in [10] regarding schemes recently proposed by Zheng. Thus we will show that there are major differences between a digital signature scheme with message recovery and authenticated encryption scheme by proposing a digital signature with message recovery scheme and signcryption scheme as an example for comparison. The security of the schemes is based on intractability of solving the Diffie Hellman problem as well as finding a collision on one-way hash-function.read more

Efficient ID-based digital signatures with message recovery
TL;DR: Two new ID-based signature schemes with message recovery are proposed, one of which can deal with messages of fixed length and the second one that can dealWith messages of arbitrary length, and both are proven secure in the random oracle model.

A public key cryptosystem and a signature scheme based on discrete logarithms
TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.
