    • n forgery The act of fabricating or producing falsely; the making of a thing in imitation of another thing, as a legal document, commercial paper or coin, a literary production, a work of art, a natural object, etc., with a view to deceive, mislead, or defraud; specifically, the act of fraudulently making, counterfeiting, or altering any record, instrument, register, note, or the like, to the prejudice of the right of another: as, the forgery of a check or a bond. In criminal law It denotes (at common law) a false making of any instrument by which one person can become obligated to another (including every alteration of or addition to a true instrument), with criminal intent, for purposes of fraud and deceit; the making or altering a writing so as to make the alteration or the writing purport to be the act of some person whose act it is not; the false making of an instrument which purports to be that which it is not, as distinguished from an instrument which purports to be what it really is, but contains false statements. The definition is much enlarged by various statutes in different jurisdictions, under which many acts not originally forgery are punishable as such. See counterfeit, n., 2.
    • n forgery That which is forged, fabricated, falsely or fraudulently devised, or counterfeited; any instrument which fraudulently purports to be that which it is not.

In science:

Menezes has pointed out to us that in it is shown that using 2 as a generator for certain discrete logarithm based signature schemes is vulnerable to forgeries, whereas in it is shown that using a random generator in these schemes is provably secure (this is summarized in ).

In this case, the test HDRsignature output by A (and thus F ) is clearly a successful forgery against OAKE-HDR.
A New Family of Practical Non-Malleable Diffie-Hellman Protocols
Putting all together, we get that { ˆA, A, X0 , Y0 } did not appear in any of the HDR-signatures issued by ˆB , and thus the test HDR-signature output by F is a successful forgery against OAKE-HDR.
A New Family of Practical Non-Malleable Diffie-Hellman Protocols
This implies that, in Case-3, the values { ˆA, A, X0 , Y0} also did not appear in any one of the responses from the signing oracle ˆB , and thus the test HDR-signature output by F is a successful forgery against OAKE-HDR.
A New Family of Practical Non-Malleable Diffie-Hellman Protocols
Intuition behind the proof is the fact that if the prefix of m 6= id, then S¬id (sk ,m) = S (sk ,m) which is of no help to the adversary as any successful forgery must be prefixed with id and all oracle queries to S¬id must be prefixed with id′ 6= id.

This means that with probability (1 − η) · ((1 − κ) − t1 ), the adversary can output a forgery.

During this transmission if A finds an x′ ∋ h(x′ ) = h(x), then (x′ , y = EK (h(x))) is a valid forgery.
A Hash of Hash Functions
Finally, suppose that A finds two distinct x, x′ ∋ h(x) = h(x′ ) and persuades S to sign h(x), then (x′ , y = EK (h(x))) is again a valid forgery.
A Hash of Hash Functions
Thus, a forgery of the modified scheme must be due to Item (2), which yields a breaking of the original scheme.
The Random Oracle Methodology, Revisited
Formally, let AR be an adversary who mounts an adaptive chosen message attack on SR , and whose success probability in obtaining an existential forgery (in the Random Oracle Model) is ǫfrg = ǫfrg (k).
The Random Oracle Methodology, Revisited
Denote by REL the event in which during an execution of AR , it hands out a message m for which (m, O(m)) ∈ R (either as a query to the signer during the chosen message attack, or as the message for which it found a forgery at the end), and let ǫrel = ǫrel (k) be the probability of that event.
The Random Oracle Methodology, Revisited
Hence the probability that AR succeeds in obtaining an existential forgery against S is at least ǫfrg − ǫrel .
The Random Oracle Methodology, Revisited
Since ǫrel is negligible, and ǫfrg is not, then AR ’s probability of obtaining an existential forgery against S is also not negligible, contradicting the assumed security of S .
The Random Oracle Methodology, Revisited
Hence, the adversary achieves existential forgery (of S ′ RF ) under key-only attack.
The Random Oracle Methodology, Revisited
Alternatively, the adversary can ask the legitimate signer for a signature on s, hence obtaining the secret signing-key (i.e., total forgery).
