Preface
LATINCRYPT 2010 was the First International Conference on Cryptology and
Information Security in Latin America and took place during August 8–11,
2010 in Puebla, Mexico. LATINCRYPT 2010 was organized by the Centro de
Investigaci´on y de Estudios Avanzados del IPN (CINVESTAV-IPN) and the
Benem´eritaUniversidadAuto´nomadePuebla(BUAP)incooperationwithThe
International Association for Cryptologic Research (IACR). The General Chair
of the conference was Francisco Rodr´ıguez Henr´ıquez.
The conference received 62 submissions and each submission was assigned
to at least three committee members. Submissions co-authored by members of
the ProgramCommittee wereassignedto atleastfive committee members.The
reviewing process was challenging due to the large number of high-quality sub-
missions,andwearedeeply gratefultothe committeemembersandexternalre-
viewers for their outstanding work. After meticulous deliberation, the Program
Committee, which was chaired by Michel Abdalla and Paulo S. L. M. Barreto,
selected19submissionsforpresentationattheconference.Thesearethearticles
included in this volume. In addition to these presentations, the program also
included four invited talks.

JacquesBeigbederfromtheE´coleNormaleSup´erieureforhelpingwiththesetup
of the reviewing website.
Finally, we would like to thank our sponsors CINVESTAV-IPN, BUAP, and
the Intel Guadalajara Design Center for their financial support as well as all
the people who contributed to the success of this conference. In particular, we
are indebted to the members of the LATINCRYPT Steering Committee and
the General Chair Francisco Rodr´ıguez Henr´ıquez for their diligent work and
for making this conference possible. We would also like to thank Springer for
accepting to publish the proceedings in the Lecture Notes in Computer Science
series.
