We propose a sufficient condition to security named Persistent_BNDC. A process is Persistent_BNDC when every of its reachable states satisfies a basic Non-Interference property called BNDC. By imposing that security persists during process execution, one is guaranteed that every potential migration is performed in a stable, secure state. We define a suitable bisimulation-based equivalence relation among processes, that allows us to express the new property as a single equivalence check, thus avoiding the universal quantifications over all the reachable states (required by Persistent_BNDC) and over all the possible hostile environments (implicit in the basic Non-Interference property BNDC). We prove that Persistent_BNDC is a sufficient condition to the security of mobile agents by (i) giving a sound and complete characterization of Persistent_BNDC in terms of dynamic contexts, i.e., execution contexts that can non-deterministically change at run-time, abstractly modelling arbitrary migrations; (ii) showing that Persistent_BNDC implies information flow security when agent mobility is explicitly expressed in the calculus. <\/jats:p>","DOI":"10.3233\/jcs-2006-14103","type":"journal-article","created":{"date-parts":[[2016,5,18]],"date-time":"2016-05-18T07:35:47Z","timestamp":1463556947000},"page":"65-110","source":"Crossref","is-referenced-by-count":18,"title":["Information flow security in dynamic contexts"],"prefix":"10.1177","volume":"14","author":[{"given":"Riccardo","family":"Focardi","sequence":"first","affiliation":[{"name":"Dipartimento di Informatica, Universit\u00e0 Ca' Foscari di Venezia via Torino 155, 30172 Venezia, Italy.,"}]},{"given":"Sabina","family":"Rossi","sequence":"additional","affiliation":[{"name":"Dipartimento di Informatica, Universit\u00e0 Ca' Foscari di Venezia via Torino 155, 30172 Venezia, Italy.,"}]}],"member":"179","published-online":{"date-parts":[[2006,2,1]]},"container-title":["Journal of Computer Security"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JCS-2006-14103","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JCS-2006-14103","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,10]],"date-time":"2025-03-10T15:59:16Z","timestamp":1741622356000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/JCS-2006-14103"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,2,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2006,2,1]]}},"alternative-id":["10.3233\/JCS-2006-14103"],"URL":"https:\/\/doi.org\/10.3233\/jcs-2006-14103","relation":{},"ISSN":["0926-227X","1875-8924"],"issn-type":[{"value":"0926-227X","type":"print"},{"value":"1875-8924","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,2,1]]}}}
