The original signer delegates his or her signing right to the proxy signer, then the proxy signer can generate valid signature on behalf of the original signer. But only the designated verifier can verify the proxy signature. Several designated verifier proxy signature schemes have been proposed. However, most of them were proven secure in the random oracle model, which has received a lot of criticism since the security proofs in the random oracle model are not sound with respect to the standard model. Recently, by employing Water\u2032s hashing technique, Yu et al. proposed a new construction of designated verifier proxy signature. They claimed that the new construction is the first designated verifier proxy signature, whose security does not rely on the random oracles. But, in this paper, we will show some attacks on Yu et al.\u2032s scheme. So, their scheme is not secure.<\/jats:p>","DOI":"10.1155\/2012\/508981","type":"journal-article","created":{"date-parts":[[2012,7,6]],"date-time":"2012-07-06T01:23:19Z","timestamp":1341537799000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Attacks on One Designated Verifier Proxy Signature Scheme"],"prefix":"10.1155","volume":"2012","author":[{"given":"Baoyuan","family":"Kang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,7,5]]},"reference":[{"key":"e_1_2_5_1_2","first-page":"1338","article-title":"Proxy signatures: delegation of the power to sign messages","volume":"79","author":"Mambo M.","year":"1996","journal-title":"IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences"},{"key":"e_1_2_5_2_2","doi-asserted-by":"crossref","unstructured":"JakobssonM.
