There are many application contexts in which guaranteeing authenticity and integrity of documents is ebential. In these cases, the typical solution relies on digital signature, which is based on the use of a PKI infrastructure and suitable devices (smart card or token USB). For several reasons, including certificate and device cost, many countries, such as the United States, the European Union, India, Brazil and Australia, have introduced the pobibility to use simple generic electronic signature, which is leb secure but reduces the drawbacks of digital signature.In this paper, we propose a new type of electronic signature that is based on the use of social networks. We formalize the proposal in a generic scenario and then, show a pobible implementation on Twitter. Our proposal is proved to be secure, cheap and simple to adopt.

Abstract
There are many application contexts in which guaranteeing authenticity and integrity of documents is ebential. In these cases, the typical solution relies on digital signature, which is based on the use of a PKI infrastructure and suitable devices (smart card or token USB). For several reasons, including certificate and device cost, many countries, such as the United States, the European Union, India, Brazil and Australia, have introduced the pobibility to use simple generic electronic signature, which is leb secure but reduces the drawbacks of digital signature.In this paper, we propose a new type of electronic signature that is based on the use of social networks. We formalize the proposal in a generic scenario and then, show a pobible implementation on Twitter. Our proposal is proved to be secure, cheap and simple to adopt.File | Dimensione | Formato | |
