Edu Cer a obtinut astazi la ora 13,40 (ora Romaniei) acceptul domnului Takeshi Shimoyama de la
Fujitsu Laboratories LTD, Japonia de a face public si pozitia dinsului trimisa Edu Cer tot astazi la ora 5,25 (ora Romaniei).
Desi aveam raspunsul dinsului nu l-am facut public pana nu aveam acordul domniei sale. Mai jos este pozitia domniei sale
care exprima faptul ca dl. Ioan Mang a comis un act de plagiat si ca domnul Shimoyama spune ferm:
‘I feel very sad such an illegal paper was submitted and was published.’
I’m Takeshi Shimoyama who is one of the authors of the paper
„Correlation Attack to the Block Cipher RC5 and the Simplified
Variants of RC6”. which was submitted to 3rd AES conference.
(http://csrc.nist.gov/archive/ aes/round2/conf3/aes3papers. html)
I read the attached paper, then I’m convinced that the paper is
plagirised version of our paper. Though the title is not same as my paper, all of the algorithms,
data and the sentences are quite same as our paper.
I feel very sad such an illegal paper was submitted and was published.
I keep researching for 15 years or more in my field (cryptanalysis). It can be declared that Mr.Mang’s insisting is completely wrong. An illegal quotation and an illegal copy are major violations, in the cryptanalysis field, as well as other academic fields, of course. In such an act, there will be a possibility giving a severe punishment, such that the submission to any conference or journal of the field from them will be prohibited in the future. Anyway, Thank you for your sending information. Sincerely yours, Takeshi Shimoyama Fujitsu Laboratories LTD.
UPDATE. Prof. dr. Eli Biham, decan al Departamentului Computer Science de la Technion, Haifa Israel, confirma pe pagina proprie de internet, cele relatate in articol
Dl. Ioan Mang sfideaza opinia publica, sfideaza bunul simt si incearca sa prosteasca in fata o intreaga comunitate academica, o tara intreaga: ‚nu a copiat, nu a plagiat, legea lui Ohm e aceiasi’. Domnia sa stie ce joc face: integritatea, asa cum a pus ca prioritate zero premierul Ponta la desemnare, ar insemna concedierea sa si a sotiei sale din sistemul academic. Având in vedere pozitiile exprimate de dl. Mang, agatarea de functie cu orice pret, am inceput demersurile pentru internationalizarea cazului.
Vorbesc mai jos expertii din stainatate, victime ale furtului grotesc. Astazi va prezentam, cu acordul domniei sale, raspunsul public al prof. dr. Eli Biham, decan al Departamentului Computer Science de la Technion, Haifa Israel. Maine vom prezenta opiniile altor specialisti din strainatate, victime ale plagiatului Mang.
Mai jos va prezentam: Informarea adresata domnului profesor Eli Biham pentru un un articol plagiat în cvasi-integralitate – altul decât prezentat ieri de Emil Boc si apoi raspunsul dânsului.
We are writing you about a possible case of plagiarism related to one of
your paper. As this situation became a public case in Romania (see
http://www.hotnews.ro/stiri-politic-12207691-emil-boc-pdl-cere-demisia-ministrului-educatiei-ioan-mang-acuzandu-plagiat.htm) and is related to our new Ministry of Education, Ioan Mang, we would
appreciate to have your oppinion about it.
Please find attached the paper „Square attack against reduced variants of
Rijndael” published by Mang I. in 2004 in an Ukrainian journal (Visnik
Sumskovo derjavnovo universitety, Seria Technichni nauki, 2004, น 12(71),
p. 129-135. http://essuir.sumdu.edu.ua/handle/123456789/10536
Our opinion is that the above mentioned paper is the most past a copy of
your paper entitled „Cryptanalysis of reduced variants of Rijndael” by
Bihan E. and Keller N., published in 1998 (?), also attached.
The main author, I. Mang, publicly denies that their paper is a plagiarism
after your paper
Moreover, Mr. Mang claims that in your field such a practice is common and
the people can freely copy parts of other papers, without a proper
Could you please tell us which is your opinion about this sitiuation and
in particular about the Mang (2004) paper?
Raspunsul prof. dr. Eli Biham, decan al Departamentului Computer Science de la Technion, Haifa Israel.
Dear Prof. dr. xxxx ,
Thanks for pointing this out.
Indeed this is a case of plagirism, where the paper „SQUARE ATTACK
AGAINST REDUCED VARIANTS OF RIJNDAEL” by IOAN MANG is an exact copy
(„copy-paste”) of the manuscript „Cryptanalysis of Reduced Variants of
Rijndael” by myself and Nathan Keller.
But I would like to add that this plagiarism is not the only issue here
that shows on the personality of Ioan Mang. You usually expect that a
person that makes plagiarism will read the plagiarized paper first.
However, it is clear that Ioan Mang never read not tried to understand
the claims in the manuscript „Cryptanalysis of Reduced Variants of
Rijndael”. He could not even develop the same results on his own,
because all the content of the manuscript „Cryptanalysis of Reduced
Variants of Rijndael” is wrong. The fact that that manuscript appears on
the Internet is only due to a mistake of a colleague that forwarded it
without the consent of the authors, while already knowing of the mistake
in it. Actually, I believe that Ioan Mang is the first person ever that
did not immediately identify the mistake in the plagiarized manuscript.
