Performance Evaluation of Certificate Revocation Using k-Valued Hash Treenication cost and a low latency for update. To solve the issues, there are many proposals including CRT (Certificate Revocation Tree), Authenticated Dictionary, and Delta List. In this paper, we study CRT using k-valued hash tree. To estimate the optimal value of k, we examine the overhead of comput

Active Rebooting Method for Proactivized System: How to Enhance the Security against Latent Virus At”. However, even though proactive maintenance is employed, it is a hard problem to detect the viruses which are skillfully developed and latent in the memory of servers. We introduce a new type of virus attacks, called ., in which viruses reside in the intruded server and wait for the chance for vir

Region-Based Watermarking for Imagesof creative digital data across the Internet. Several schemes, with their merits and demerits, have been proposed to date. However, many of them rely on the presentation of a test image in an appropriate format before the detection can proceed. In most cases this is achieved through some form of pre

A Secrecy Scheme for MPEG Video Data Using the Joint of Compression and Encryptionproposed algorithm is a method which combines an encryption with MPEG video compression. Furthermore, it has short processing times for the encryption and provides sufficient security from the viewpoint of visibility and signal to noise ratio values. Thus the proposed method is suitable for the prot
