Cloud computing is a hot topic in recent years. It exhibits the following key characteristics: agility, low cost in using, device and location independence, virtualization, reliability, scalability and elasticity, performance and etc. All those features show fascinating benefit to companies. As they can get free from the worry about the investment on hardware and can […]
Encrypted Information Hiding in the Spatial Domain
The concept of encrypted information hiding has been presented. The use of cryptographic algorithms together with steganography and watermarking methods make it almost impossible for interceptor to recover the encrypted hidden data as this requires the interceptor to detect the existence of the information before attempting to decrypt it. To recover the original data, the […]
Bandwidth scheduling and path computation algorithms for connection-oriented Networks
An increasing number of high-performance networks provision dedicated channels through circuit switching or MPLS/GMPLS techniques to support large data transfer. The link bandwidths in such networks are typically shared by multiple users through advance reservation, resulting in varying bandwidth availability in future time. Developing efficient scheduling algorithms for advance bandwidth reservation has become a critical […]
