- In this paper, the grouped scheme is specially applied to compute the fast Fourier transform (FFT) when the portions of transformed outputs are calculated selectively. The groupe...
We consider the fundamental problem of authenticated group key exchange among n parties within a larger and insecure public network. A number of solutions to this problem have bee...
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...
In this paper, we describe simple techniques for object group manipulation, an important operation in user interaction with a Virtual Environment. All presented manipulation techn...
In this paper we investigate a new architecture for recognizing human group actions in meetings. These group actions provide a basis that enables effective browsing and querying i...
