Forward-Secure Threshold Signature Schemes
2001We construct forward-secure threshold signature schemes. These schemes have the following property: even if more than the threshold number of players are compromised, it is not possible to forge signatures relating to the past. This property is achieved while keeping the public key fix ed and updating the secret keys at regular intervals.

Economics of Cyber Security and the Way Forward
International Journal of Cyber Warfare and Terrorism, 2016Initiatives carried by companies, institutes and governments to flourish and embellish the Information and Communication Technology (ICT) among the public have led to its penetration into every walk of life. ICT enhances the efficiency of various systems, such as the organisation and transfer of data.

On the Security of the Non-Repudiation of Forwarding Service
2012Nowadays, digital data can be protected by several security services. For example, confidentiality can be provided using encryption mechanisms and authentication can be realized by digital signatures. However, it is usually assumed that only unauthorized users want to manipulate data or attack the system.

Efficient Forward-Secure Threshold Signatures
2020Forward-secure threshold signatures are useful to mitigate the damage of secret key exposure. Constructions based on bilinear pairings are particularly interesting because they achieve shorter signatures than RSA-based constructions.

Forward-Security in Private-Key Cryptography
2003This paper provides a comprehensive treatment of forwardsecurity in the context of shared-key based cryptographic primitives, as a practical means to mitigate the damage caused by key-exposure. We provide definitions of security, practical proven-secure constructions, and applications for the main primitives in this area.

IoT Security Challenges and Ways Forward
Proceedings of the 6th International Workshop on Trustworthy Embedded Devices, 2016Today 2.9 billion people, or 40% of the world's population are online. By 2020, at least 40 billion more devices will become smart via embedded processors. The impact of such Internet of Things (IoT) on our society will be extraordinary. It will influence most consumer and business sectors, impact education, healthcare and safety. However, it certainly

Weak Forward Security in Mediated RSA
2003Mediated RSA (mRSA) [1] is a simple and practical method of splitting RSA private keys between the user and the Security Mediator (SEM). Neither the user nor the SEM can cheat each other since a signature or a decryption must involve both parties. mRSA allows fast and fine-grained control (revocation) of users' security priviliges.

Forward Secure Attribute-Based Signatures
2012Attribute-Based Signatures (ABS) is a versatile primitive which allows an entity to sign a message with fine-grained control over identifying information. A valid ABS only attests to the fact that "A single user, whose attributes satisfy the predicate, has endorsed the message".
