These are the proceedings of Eurocrypt 2008, the 27th Annual IACR Eu-
crypt Conference. The conference was sponsored by the International
Asso- ation for Cryptologic Research (www.iacr.org), this year in
cooperation with Tubitak (www.tubitak.gov.tr). The Eurocrypt 2008
Program Committee (PC) consisted of 28 members whose names are listed on
the next page. There were 163 papers submitted to the conference and the
PC chose 31 of them. Each paper was assigned to at least three PC
members, who either handled it themselves or assigned it to an external
referee. After the reviews were submitted, the committee deliberated
