  • a two phase local server security model based on xml Certificate
    Lecture Notes in Computer Science, 2006
    Co-Authors: Yonghwa Kim, Jinsung Kim, Yongsung Kim, Jangsup Shim
    Abstract:

    This paper proposes server security Certificate management system applying the mechanism of public key infrastructure and XML Security technology specification to secure the information and resources open in network. This model is the system that permits the access only to the authorized users at a Request of the status of the Certificate through certifying server after issuing and Requesting wire, wireless Certificate on-line and registering on the XML Certificate managing server. Also, this paper investigates the methods to support independent and various styles of information exchanges at platform using SOAP Message to provide remote server with the service of Certificate Request and inquiry.

  • CISIS - On secure JAVA application in SOA-based PKI mobile government systems
    Computational Intelligence in Security for Information Systems, 2011
    Co-Authors: Milan Marković, Goran Ðorðević
    Abstract:

    In this paper, we describe a possible model of secure m-government system based on secure JAVA mobile application and SOA-Based mgovernment platform. The proposed model consists of additional external entities/servers, such as: PKI, XKMS, STS, UDDI and TSA. The main parts of the proposed model are secure JAVA mobile application and secure Web Service implemented on the SOA-based platform. One example of the possible mobile government online services is particularly emphasized: sending m-residence Certificate Request and obtaining the m-residence electronic document (m-residence Certificate) as a government's response. This scenario could serve as a model of any m-government online services consisting of sending some Requests to the m-government platforms and obtaining responses as corresponding governmental electronic messages or documents.

  • On Secure SOA Based e/m-Government Systems
    ISSE 2011 Securing Electronic Business Processes, 2012
    Co-Authors: Milan Marković
    Abstract:

    In this paper, a possible model of secure e/m-government system based on secure desktop or JAVA mobile application and SOA-Based e/m-government platform is described. The proposed model consists also of additional external entities/servers, such as: PKI, XKMS, STS, UDDI and Time Stamping Authority. An example of the secure e/m-government online services is particularly emphasized: sending e/m-residence Certificate Request and obtaining the e/m-residence electronic document (e/m-residence Certificate) as a municipality’s response. This scenario example could also serve as a model for any e/m-government online services consisting of sending some Requests to the e/m-government platforms and obtaining responses as corresponding governmental electronic documents.

  • One Possible Model of Secure e/m-Government System
    Information Systems Management, 2010
    Co-Authors: Milan Marković, Goran Đorđević
    Abstract:

    In this article, we describe a possible model of secure e/m-government system based on secure JAVA mobile application and SOA-Based e/m-government platform. The proposed model consists of additional external entities/servers, such as: PKI, XKMS, STS, UDDI and Time Stamping Authority. The main parts of the proposed model are secure JAVA mobile application and secure Web Service implemented on the SOA-based platform capable to connect mobile and desktop applications. One example of the mobile government online services is particularly emphasized: sending m-residence Certificate Request and obtaining the m-residence electronic document (m-residence Certificate) as a municipality's response.

  • EUROCRYPT - The Power of Proofs-of-Possession: Securing Multiparty Signatures against Rogue-Key Attacks
    Advances in Cryptology - EUROCRYPT 2007, 2007
    Co-Authors: Thomas Ristenpart, Scott Yilek
    Abstract:

    Multiparty signature protocols need protection against rogue-key attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, provable security has only been established under the knowledge of secret key(KOSK) assumption where the adversary is required to reveal the secret keys it utilizes. In practice, certifying authorities rarely require the strong proofs of knowledge of secret keys required to substantiate the KOSK assumption. Instead, proofs of possession(POPs) are required and can be as simple as just a signature over the Certificate Request message. We propose a general registered keymodel, within which we can model both the KOSK assumption and in-use POP protocols. We show that simple POP protocols yield provable security of Boldyreva's multisignature scheme [11], the LOSSW multisignature scheme [28], and a 2-user ring signature scheme due to Bender, Katz, and Morselli [10]. Our results are the firstto provide formal evidence that POPs can stop rogue-key attacks.
