SCOPE AND TOPICS
The 2nd International  Workshop  on  Security  Issues  in Coordination
Models, Languages and Systems follows the success of SecCo'03 (held in
conjunction with ICALP'03).

New  networking  technologies require  the  definition  of  models and
languages adequate for  the  design  and  management  of  new  classes
of applications. Innovations are  moving  in  two  directions:  on the
one hand, the Internet which supports wide area applications,  on  the
other hand, smaller networks of  mobile  and  portable  devices  which
support   applications   based   on   a   dynamically   reconfigurable
communication  structure.  In  both cases, the challenge is to develop
applications  while  at  design  time  there  is no knowledge  of  the
availability and/or location of the involved entities.

Coordination models,  languages  and  middlewares,  which  advocate  a
distinct separation between the internal behaviour of the entities and
their interaction, represent a promising approach. However, due to the
openness of these systems, new critical aspects come into  play,  such
as the need to deal  with  malicious  components  or  with  a  hostile
environment. Current research on network security issues (eg. secrecy,
authentication,  etc.)  usually   focuses   on  opening  cryptographic
point-to-point tunnels. Therefore, the proposed solutions in this area
are  not  always  exploitable   to   support   the  end-to-end  secure
interaction between entities  whose  availability  or  location is not
known beforehand. Topics of interest include, but are not limited to:

      Theoretical foundations, specification, analysis,  case-studies,
      applications for

      authentication                               coordination models
      integrity                                 web service technology
      privacy                                   mobile ad-hoc networks
      confidentiality                      agent-based infrastructures
      access control           -in-               peer-to-peer systems
      denial of service                               global computing
      service availability                     context-aware computing
      safety aspects                           component-based systems
      fault tolerance                   ubiquitous/pervasive computing

SUBMISSION GUIDELINES
    Submissions may be of two forms:
    o Short abstracts: up to 5 pages 11 pt,
    o Full papers: up to 12 pages 12 pt.
    They should be submitted according to the instruction available at
    the workshop web page: http://cs.unibo.it/secco04
    The workshop proceedings will be published  in  the  ENTCS  series
    (Electronic Notes in Theoretical Computer  Science)  and, as  done
    for SecCo'03,  we  intend  to  publish  a  journal  special  issue
    inviting full versions of papers selected among those presented at
    the workshop.
