Networks update, and as the battlement works are destroyed, there are changes in how, in the encryption of how different military communications work. it becomes even harder for russia had to do the kinds of attacks that they may have planned, three, four, five months ago. the thing is just gets harder as the environment gets more complex. i want to ask you more about those satellite attacks. based on new reporting tonight from reuters, western intelligence agencies are investigating a cyber attack by unidentified hackers that disrupted broadband satellite internet access inside ukraine, coinciding with russia s invasion. and these agencies are assessing whether this was the work of a russian state back attackers, preparing the battlefield by attempting to sever communications. jacqui, can you talk to us about this type of cyber war, attacking satellites? the impact it could have more broadly on ukraine s military? yeah, and this is actually ....

"ROSE: Robust Searchable Encryption with Forward and Backward Security" by Peng Xu, Willy Susilo et al.

Dynamic searchable symmetric encryption (DSSE) has been widely recognized as a promising technique to delegate update and search queries over an outsourced database to an untrusted server while guaranteeing the privacy of data. Many efforts on DSSE have been devoted to obtaining a good tradeoff between security and performance. However, it appears that all existing DSSE works miss studying on what will happen if the DSSE client issues irrational update queries carelessly, such as duplicate update queries and delete queries to remove non-existent entries (that have been considered by many popular database system in the setting of plaintext). In this scenario, we find that (1) most prior works lose their claimed correctness or security, and (2) no single approach can achieve correctness, forward and backward security, and practical performance at the same time. To address this problem, we study for the first time the notion of robustness of DSSE. Generally, we say that a DSSE scheme is r ....

"Privacy-preserving file sharing on cloud storage with certificateless " by Pairat Thorncharoensri, Willy Susilo et al.

In recent years, data generated by Internet of Things (IoT) devices has become increasingly massive. The amount of data stored in the cloud is also enormous and needs to be processed in a timely, efficient, secure, and private manner. While data stored on the cloud is guaranteed to be available, this does not mean that the secrecy and privacy of the sender are guaranteed. Moreover, sharing data on the cloud may sometimes lead to unpleasant surprises, such as undeniable disputes due to the shared content. Our certificateless signcryption (CLSC) scheme is proposed to address the above issues. It provides unforgeability, indistinguishability, non-transferability, and privacy of sender identity to ensure secrecy and privacy of the sender. Our contributions are not only limited to solving the aforementioned issues. The security model of non-transferability and privacy of sender identity for the signcryption scheme is first proposed. This is followed by a concrete simulation of the proof. In ....
