Design e implementação de uma arquitetura conceitual para a criação de social botnet em redes sociais 在社交网络中创建社交僵尸网络的概念架构的设计与实现
V. Leite, R. Salles
As implicações de segurança diante dos socialbots são evidentes por causa da grande quantidade de usuários que as redes sociais apresentam e da alta capacidade de compartilhamento de dados, que traz como consequência a elevada propagação de informação. Com base nisto, o objetivo desta pesquisa é apresentar uma proposta de arquitetura conceitual para a criação de social botnet capaz de ser usada junto às ferramentas de detecção para a simulação de socialbots. Ao implementá-la no Facebook, uma análise da segurança dessa rede social é realizada para apresentar os aspectos observados que precisam ser aprimorados por ela e pela área de detecção de social botnet.
社交机器人的安全含义是显而易见的,因为社交网络提供了大量的用户和高数据共享能力,这导致了信息的高传播。在此基础上,本研究的目的是提出一个概念架构的建议,以创建社交僵尸网络,能够与检测工具一起用于模拟社交机器人。当它在Facebook上实施时,对该社交网络的安全性进行了分析,提出了观察到的需要改进的方面,以及社交僵尸网络检测领域。

Alternative N-bit Key Data Encryption for Block Ciphers 分组密码的备选n位密钥数据加密
K. M. C. Damasceno, C. Cruz, Anderson de Oliveira, Luís De Castro
Post-encryption patterns are cribs that can be used by adversaries to unlock the encryption key both in symmetric or asymmetric cryptography, compromising security. Different methods to mitigate the problem, with their advantages and disadvantages, can be found in the literature, including one-time pad encryption, code-based cryptography and cipher block chaining. This work presents an alternative technique to generate an n-bit, n-block and key cipher that can be derived from reasonable short length key. The proposed technique is able to mitigate post-encryption patterns. Experimental results asserting the capabilities of the proposed cipher techniques are presented and discussed in the text.
加密后模式是攻击者可以使用的漏洞,可以在对称或非对称加密中解锁加密密钥,从而损害安全性。缓解这一问题的不同方法各有优缺点,可以在文献中找到,包括一次性垫加密、基于代码的加密和密码块链。本文提出了一种从合理的短长度密钥中生成n位、n块和密钥密码的替代技术。所提出的技术能够减轻后加密模式。实验结果证明了所提出的密码技术的能力,并在文中进行了讨论。

Uma análise preliminar do controle de forks no mecanismo de consenso Proof-of-Stake com Tempo Discreto 离散时间权益证明共识机制分叉控制的初步分析
Diego Martins, M. Henriques
Este artigo apresenta uma análise preliminar do mecanismo de consenso para blockchains baseado em Proof-of-Stake com Tempo Discreto (PoSTD). O texto explica os mecanismos que controlam a criação de novos blocos e a eliminação de forks na cadeia. Em seguida, o mecanismo de consenso é analisado de forma genérica, através de diferentes cenários na visão de um determinado nó. É mostrado como o algoritmo atinge o consenso mesmo com atrasos na rede, desde que o tempo de duração de uma rodada de trabalho seja superior ao maior dos atrasos de comunicação entre dois nós quaisquer conectados no sistema.
本文对基于离散时间权益证明(PoSTD)的区块链共识机制进行了初步分析。本文解释了控制新区块创建和链分叉删除的机制。然后,通过给定节点的不同场景,对共识机制进行一般性分析。它展示了该算法是如何在网络延迟的情况下达成共识的,只要工作轮的持续时间大于系统中任何两个连接节点之间的最大通信延迟。

Understanding the effects of removing common blocks on Approximate Matching scores under different scenarios for digital forensic investigations 了解在数字取证调查的不同场景下,去除常见块对近似匹配分数的影响
V. Moia, Frank Breitinger, M. A. Henriques
Finding similarity in digital forensics investigations can be assisted with the use of Approximate Matching (AM) functions. These algorithms create small and compact representations of objects (similar to hashes) which can be compared to identify similarity. However, often results are biased due to common blocks (data structures found in many different files regardless of content). In this paper, we evaluate the precision and recall metrics for AM functions when removing common blocks. In detail, we analyze how the similarity score changes and impacts different investigation scenarios. Results show that many irrelevant matches can be filtered out and that a new interpretation of the score allows a better similarity detection.
在数字取证调查中发现相似性可以通过使用近似匹配(AM)功能来辅助。这些算法创建对象的小而紧凑的表示(类似于哈希),可以通过比较来识别相似性。然而,由于通用块(在许多不同文件中发现的数据结构,而不考虑内容),结果往往会有偏差。在本文中,我们评估了AM函数在去除公共块时的精度和召回率指标。我们详细分析了不同调查场景下相似度得分的变化和影响。结果表明,许多不相关的匹配可以被过滤掉,并且分数的新解释允许更好的相似性检测。

An Approach for Adaptive Security of Cloud Applications within the ATMOSPHERE Platform ATMOSPHERE平台内云应用的自适应安全方法
Jorge Da Silva, A. Braga, C. M. F. Rubira, R. Dahab
Self-protecting systems can reduce response time to known attacks by automating decision-making processes in security operations. This paper briefly describes the ATMOSPHERE platform for monitoring and enforcement of trustworthiness in cloud systems, as well as proposes a way to enhance its Trustworthiness Monitoring & Assessment framework (responsible for analyzing and planning adaptation actions) in order to instantiate the concept of adaptive security for self-protecting cloud infrastructures and applications. The paper approaches adaptive security based upon adaptive Web Application Firewalls, and enhances a software-based, feedback control loop (named MAPE-K) for monitoring and analysis of security events, as well as the planning and execution of adaptation actions for securing cloud applications. This is a work in progress, currently under development, to be integrated to ATMOSPHERE's framework.
自我保护系统可以通过自动化安全操作中的决策过程来减少对已知攻击的响应时间。本文简要介绍了用于云系统可信度监测和执行的ATMOSPHERE平台,并提出了一种增强其可信度监测和评估框架(负责分析和规划适应行动)的方法,以实例化自适应安全的概念,用于自我保护云基础设施和应用程序。本文采用基于自适应Web应用防火墙的自适应安全方法,并增强了一个基于软件的反馈控制回路(名为MAPE-K),用于监控和分析安全事件,以及规划和执行保护云应用程序的自适应行动。这是一项正在进行的工作,目前正在开发中,将纳入大气层的框架。

K-Anonymity technique for privacy protection: a proof of concept study 隐私保护的k -匿名技术:概念验证研究
Ítalo Santos, E. Coutinho, Leonardo Moreira
Privacy is a concept directly related to people's interest in maintaining personal space without the interference of others. In this paper, we focus on study the k-anonymity technique since many generalization algorithms are based on this privacy model. Due to this, we develop a proof of concept that uses the k-anonymity technique for data anonymization to anonymize data raw and generate a new file with anonymized data. We present the system architecture and detailed an experiment using the adult data set which has sensitive information, where each record corresponds to the personal information for a person. Finally, we summarize our work and discuss future works.
隐私是一个概念,与人们在不受他人干扰的情况下保持个人空间的利益直接相关。由于许多泛化算法都是基于这种隐私模型,因此本文重点研究了k-匿名技术。因此,我们开发了一个概念证明,该概念证明使用k-匿名技术进行数据匿名化,以匿名化原始数据并生成具有匿名数据的新文件。我们介绍了系统架构,并详细介绍了使用具有敏感信息的成人数据集的实验,其中每个记录对应一个人的个人信息。最后,对工作进行了总结,并对今后的工作进行了展望。
