Successful Master Thesis Defense of Misbah Irum -- 2014-09-07

KTH - AIS Lab would like to congratulate Ms. Misbah Irum on her successful thesis defense. In her thesis titled “Secure User Centric Access Control Policy Management Framework for Cloud Applications”, she proposed new approach for access control in Cloud which externalizes access control from Cloud applications and enables users to create and manage access control policies on their resources according to their own security and access control requirements. The framework also provides users with a central control point and a standard policy definition language to specify and manage access control on all their resources scattered across the Cloud. she presented the framework and described the protocol which defines the interaction between different components of the system to specify and enforce User-Centric policies using XACML standards. To show the applicability of the designed framework she developed a prototype using Google spreadsheet as the Cloud application. The evaluation of the prototype verifies the claims of the user centric access control framework in providing users with the control to define access control policies according to their requirements on their resources. Real world Cloud application is used to show the applicability and integration of the designed framework with existing Cloud applications. Best wishes to Misbah in all of her endeavors!

These models are implemented using Extensible Access Control Markup Language (XACML) providing a challenging research area. This project required proficiency in Java, J2SE, J2EE, JSP, Servlets, Web services, XML, SAML, Apache Tomcat Server and Cryptographic techniques.


Successful Master Thesis Defense of Sehar Iqbal -- 2014-05-08

KTH - AIS Lab would like to congratulate Ms. Sehar Iqbal on her successful thesis defense. In her thesis titled “Quantifying the impact of randomness in simulation based studies”, she performed scientific studies in Wireless Sensor Networks rely on simulations. Simulations are heavily dependent on random numbers and researchers generally use random numbers generated through common random number generating APIs of programming languages. Thus, in this research, she studied the impact of using different types of random numbers in a simulation based study of WSN. She used eight different types of random numbers generated through various algorithms. These random numbers are first evaluated using standard random number testing procedures such as Run Test, Serial Test, and Chi square Test. Then she used the same random numbers in a Markov chain based probabilistic study of Wireless Sensor Networks. We congratulate Sehar on this achievement


Successful Master Thesis Defense of Umer Khalid -- 2014-04-04

KTH - AIS Lab would like to congratulate Mr. Umer Khalid on his successful thesis defense. In his thesis titled “Secure and Privacy Enhanced Authentication & Authorization in Cloud”, he provides the design and implementation of an anonymous authentication and authorization protocol as a solution to these problems. The solution consists of carefully selected components such as, FIPS 196 for a proven and robust authentication mechanism, whereas, XACML based Policy Enforcement Point (PEP) for authorization. An identity management system (IDMS) is chosen in order to maintain a record of the registered users. For anonymity, the designed protocol uses traceable anonymous certificates (TAC’s) instead of simple public key certificates generated using anonymous identities (AID). A client side application passes these certificates as initial parameters for authentication to a strong authentication server (SA server). Certificates are modified further such that they do not leak any Personal Identifiable Information (PII) about the users. Authorization is provided using standard XACML based access control policies which are binded to the anonymous identities of the registered users instead of real identities. Hence using this protocol, threats such as identity theft and leakage can be mitigated with minimal changes to existing setups. In order to validate the designed protocol, Scyther is used. Congratulations Umer for your successful thesis defense! We wish you continued success in your career.


Successful Master Thesis Defense of Muhammad Kazim -- 2014-04-01

KTH - AIS Lab would like to congratulate Mr. Muhammad Kazim on his successful thesis defense. In his thesis titled “Virtual Machines image protection in Cloud computing”, he addressed the attacks faced by virtual machines both for protecting the sensitive customer data and maintains the integrity of virtual machines.

Successful Master Thesis Defense of Faisal Karim Bhutta -- 2014-01-01

KTH - AIS Lab would like to congratulate Mr. Faisal Karim Bhutta on his successful thesis defense. In his thesis titled “Smartphone based Authentication & Authorization Protocol for Smart Physical Access Control System (SPACS)”, he designed architecture for PACS along with security protocol for smartphone that is used for identity verification, authentication and authorization in PACS. The designed authentication protocol is an extension of two-factor authentication protocol described in FIPS-196 standard. Furthermore, the usage of symmetric key cryptography provides an efficient solution to achieve confidentiality of messages exchanged between components of designed PACS. In order to ensure the presence of the legitimate user in the premises, the system uses a pass-code feature that is only valid for one time usage. Hence using designed protocol, user’s smartphone can act as authenticator in the system. Since, the solution may be used by the non-technical persons so it is designed that it should be user friendly and require minimum efforts for configuration of security parameters. In order to validate the security of designed protocol, automated protocol verification tool Scyther is used. After validation, it is verified that our security protocol resists against Man-in-the-Middle, replay and attacks on confidentiality of user’s credentials. Good wishes to Faisal for future endeavors.

Successful Master Thesis Defense of Um-e-Ghazia -- 2013-03-27

The KTH-AIS Lab Group would like to congratulate Miss Um-e-Ghazia on her successful thesis defense! Her thesis titled “Usage based Access Control for Web based Applications” was carried out in two main directions where she explored the applicability of Usage based access control model in different applications and environments. Her theoretical work highlights the essential features that must be incorporated in access control models to cater dynamism of Cloud environment. She analyzed and compared number of Cloud based access control models through NIST defined access control metrics. Her results indicate that UCON model is the most appropriate model that can perform better according to specifications of Cloud environment. She has proposed the UCON profile in eXtensible access control markup language (XACML). This UCON profile has been formulated by the addition of newly created attributes and identifiers in XACML that enable organizations to deploy this model in different scenarios. During her thesis, she published two research papers titled “Comparative Analysis of Access Control Systems on Cloud” and “Usage Control Model Specification in XACML Policy Language”. We will sorely miss her intelligence, enthusiasm and mentorship in the lab, and although we weigh her departure with a heavy heart, we anticipate great things in her future. Best wishes to Ghazia in all of her endeavors!


Successful Master Thesis Defense of Muhammad Asif -- 2013-01-02

KTH - AIS Lab would like to congratulate Mr. Muhammad Asif on his successful thesis defense. In his thesis titled “Generic Light Weight Certificate Management Protocol”, he designed Generic Light Weight Certificate Management Protocol (GLCMP). He adopted a holistic approach in order to solve complex certificate management task. In order to achieve desired objectives, proxy based architecture has been adopted to offload computational intensive operations from mobile devices. In GLCMP, the trust between mobile device and proxy server is developed without exchanging any secret information on network. In addition, GLCMP is designed and developed by using the concept of generic security objects. The claimed security properties (authentication, confidentiality and non-repudiation) of the protocol are formally verified by employing formal Z-Notation modeling. In Z-Notation modeling, different attacks are formalized on messages exchanged between components and discussed all possible scenarios in which an attacker can attack the protocol.  Congratulations Asif and best wishes for future.
