The development of plastic card printers has led to the widespread use of identity documents printed on plastic cards, such as ID cards, driving licenses, and access key cards. This paper presents a new security feature based on a technique for embedding a ...
Inter-Vehicular Communications (IVC) are a cornerstone of the future intelligent transportation systems. A crucial enabling component of IVC is its security and privacy. Indeed, as vehicular computing systems become interconnected, there will be new venues ...
The concept of middleware based architectures for telecommunication services in the broadband, multimedia, and information era is emerging. One representative example is the Telecommunications Information Networking Architecture (TINA), which is characteri ...
TINA specifies an open architecture for telecommunication services in the broadband, multimedia, and information era. Its characteristics most relevant for security are a variety of services, a multitude of service providers, a well defined business model, ...
This paper introduces the XTR public key system. XTR is based on a new method for representing elements of a subgroup of a multiplicative group of a finite field. Application of XTR in cryptographic protocols leads to substantial savings both in communicat ...
We investigate secure routing in ad hoc networks in which security associations exist only between a subset of all pairs of nodes. We focus on source routing protocols. We show that to establish secure routes, it is in general not necessary that security a ...
In this paper, we propose a Secure JPEG, an open and flexible standardized framework to secure JPEG images. Its goal is to allow the efficient integration and use of security tools enabling a variety of security services such as confidentiality, integrity ...

To be efficient, data protection algorithms should generally exploit the properties of the media information in the transform domain. In this paper, we will advocate the use of non-linear image approximations using highly redundant dictionaries, for securi ...
