1987, Neal Koblitz, A Course in Number Theory and Cryptography, Springer, page 81:In our example of the affine cryptosystem family, deciphering is also accomplished by an affine map, namely
, and so the deciphering transformation uses the same algorithm as the enciphering transformation, except with a different key, namely, the pair
.
2015, Ping Ngai Chung, Craig Costello, Benjamin Smith, “Fast, uniform, and compact scalar multiplication for elliptic curves and genus 2 Jacobians with applications to signature schemes”, in arXiv:Our results show that many existing fast pseudomultiplication implementations (hitherto limited to applications in Diffie--Hellman key exchange) can be wrapped with simple and efficient pre-and post-computations to yield competitive full scalar multiplication algorithms, ready for use in more general discrete logarithm-based cryptosystems, including signature schemes.
