    The non-repudiation as an essential requirement of many applications can be provided by the asymmetric key model. With the evolution of new applications such as mobile commerce, it is essential to provide secure and efficient solutions for the mobile environments. The traditional public key cryptography involves huge computational costs and is not so suitable for the resource-constrained platforms. The elliptic curve-based approaches as the newer solutions require certain considerations that are not taken into account in the traditional public key infrastructures. The main contribution of this paper is to introduce a Lightweight Public Key Infrastructure (LPKI) for the constrained platforms such as mobile phones. It takes advantages of elliptic curve cryptography and signcryption to decrease the computational costs and communication overheads, and adapting to the constraints. All the computational costs of required validations can be eliminated from end-entities by introduction of a validation authority to the introduced infrastructure and delegating validations to such a component. LPKI is so suitable for mobile environments and for applications such as mobile commerce where the security is the great concern.Comment: 6 Pages, 6 Figure

    Con el crecimiento exponencial de terminales m贸viles que se est谩 dando en el mercado internacional actual, las necesidades de los usuarios est谩n variando tanto a nivel personal como corporativo. Al aumentar la cantidad de operaciones que un usuario puede realizar desde su dispositivo m贸vil, la informaci贸n personal que se almacena es mayor. Si las operaciones implican un compromiso legal por parte del usuario, los datos deben ser debidamente protegidos y avalados. Dada esta situaci贸n, se estima de vital importancia la creaci贸n de entornos que permitan al usuario identificarse de manera que su identidad no pueda ser comprometida. Un ecosistema implica la creaci贸n, gesti贸n y distribuci贸n de certificados. 脡sta es la forma tecnol贸gicamente m谩s avanzada actualmente para su uso desde terminales m贸viles. Para almacenar los datos del usuario de forma segura, se estudian las opciones de uso de elementos seguros. El ecosistema que se crea en este proyecto de Fin de M谩ster hace segura la firma de documentos digitales de forma remota mientras se est谩 fuera de la oficina o lejos del interesado, y permitir谩 la investigaci贸n de nuevos elementos que contribuyan a garantizar la autenticidad de acciones y documentos

    Future healthcare directions include individuals being monitored in real-time during day-to-day activity using wearable sensors. This thesis solves a critical requirement, that of intelligently managing when body sensors should alert doctors of changes to a person’s health status, bringing existing research closer to live health monitoring
