“…"To resist packet loss, the hash of a packet is embedded in both a forward chain of packets within the same layer and a downward chain of packets across multiple layers. the sender sends the signature packet at the end of each block" [21]. However, the main drawback of this approach is that it requires buffering a large number of packets on both the sender and receiver sides.…”

“…We examine the multicasting of signed Data Streaming on the Internet as it is presented in the study of Perig and al. [15,21]. The system requirements use a data rate of 2 Mbyte/s, with 512 packets of 512 bytes being sent every second, and a verification delay less than 1 second.…”

“…To evaluate the performance of the proposed approach we run simulations of Flex hash chain [21], TIM [19], RLH [26], EMSS [15], MLCC [25], to determine the needed redundancy degree by each mechanism using PLR equals to 30%, 20% and 10%( to achieve the verification probability 99% ). The results of this simulation are used for evaluation in subsection 4.2 (Tables 3).…”

“…the first methods are used for source authentication without ensuring non-repudiation, while hash/digital signature-based methods are used when ensuring non-repudiation is necessary. To verify the data origin authentication of a multicast stream with nonrepudiation, two categories have been presented: performed signature schemes [13][14][15][16][17][18] and amortizing the cost of signatures over multiple packets [15,[19][20][21][22][23][24][25][26][27][28]. The former uses the sender's private key to sign a hash of each message of the data transferred but suffers from high communication and computation overheads.…”

Multicast services offer a significant advantage of resource conservation for multicast senders and increase network efficiency by reducing network traffic. However, treating security concerns such as source authentication is important, especially for applications like online news, IPTV, video streaming, and stock quote distribution. Despite extensive research efforts to provide source authentication for multicast applications, there is no efficient approach that can effectively handle the requirements of the dynamic nature of multicast mobile receivers and networks. This paper provides an analysis of 22 years of research on source authentication mechanisms with non-repudiation. The majority of these mechanisms do not consider the dynamic nature of mobile users and networks. In response to this, we propose a new selective hash-based approach for multicast source authentication in Software Defined Mobile Network (SDMN). Using the advantages of the controller global view in SDMN, our approach is designed to operate in mobile and dynamic environments, provide non-repudiation, and tolerate packet loss. Our simulation results demonstrate that the proposed mechanism utilizes resources effectively, reduces communication and delay overhead, and works well in dynamic scenarios.

Widely accepted explicit authentication protocols are vulnerable to a series of attacks, for example, shoulder surfing and smudge attacks, leaving users with the constant burden of periodic password changes. As such, we propose a novel framework for continuous authentication on smartphones. This approach is guided by pattern unlocking, which is widely used and will not cause learning cost. After collecting multi‐modal data that describe both behavioral and contextual information, we employ a multi‐branch context‐aware attention network as the representation learner to perform feature extraction, then an auto encoder is then used for authentication. To overcome challenges, including cold‐start and few‐shot training, which is less discussed in other works, we incorporate transfer learning with a coarse‐to‐fine pre‐training workflow. Additionally, we deploy a hierarchical approach to offload model tuning overhead from smartphones. Extensive experiments on more than 68 000 real‐world recordings validate the effectiveness of the proposed method, with an EER (equal error rate) of 2.472% under mixed contexts, which consistently outperforms state‐of‐the‐art approaches under both static and mixed contexts.
