Attacking Predictable IPsec ESP Initialization Vectorsfidentiality. By using an adaptive chosen plaintext attack, an attacker can break low entropy plaintext blocks using brute force, and confirm guesses of the contents of arbitrary plaintext blocks. We analyze the preconditions and the seriousness of such attacks, and provide results of practical atta

A Robust Block Oriented Watermarking Scheme in Spatial Domainsome of these blocks are modified depending on the key, which is a secret random binary string of length . < .. Given an attacked image, the recovery process generates a bit pattern of length . and we show that from this pattern it is possible to get back the exact key using either standard correlat

A Flexibly Revocable Key-Distribution Scheme for Efficient Black-Box Tracing number of subscribers can be revoked in each distribution under an assumption that the number of revoked subscribers who collude in one coalition is limited to a threshold, while the maximum number of revoked ones cannot be changed in previous schemes. The flexibility in revocation is significant s
