In this paper, we present a simple method for generating random-based signatures when random number generators are either unavailable or of suspected quality (malicious or accident...
In pervasive computing environments, powerful handheld devices with wireless connections create opportunities for many new nomadic applications. We propose a new service discovery...
In this paper, we present a tool allowing the design of orchestration at a high level of abstraction. This tool also allows specifying security properties, also in an way, as anno...
Wireless Sensor Networks are extremely vulnerable against any kind of internal or external attacks, due to several factors such as resource-constrained nodes and lack of tamper-res...
In resent years, Popescu proposed several group signature schemes based on the Okamoto-Shiraishi assumption in [8–11], and claimed his schemes are secure. However, this paper dem...
