A cryptographic communication system is secure from a practical point of view if the encryption scheme can be broken after X years, where X is determined by security needs and existing technology. Quantum cryptography does not offer a complete solution for all cryptographic problems: secure keys, encryption algorithms based on them, message authentication and finding ways to detect/prevent interception; but it can be seen as a complement to standard symmetric cryptographic systems. This paper presents the implementation of the BB84 quantum key distribution protocol on mobile systems - Amov-lab’s Z410 drone with T-engine 2216 - and tracks the error rate obtained in flight conditions.

Attribute-Based Encryption is a relatively new concept in the field of cryptography, and it allows only the authorized entities to decrypt a message. This type of encryption is the mechanism by which the users may encrypt and decrypt data based on user attributes. This paper proposes the first quantum alternative of the scheme Key-Policy Attribute-Based Encryption, where the information, the encryption/decryption key, and the attributes are made of qutrits.

<p>Online banking and other e-banking modes are a very convenient way to banking in terms of speed, convenience and delivery costs, but they have brought many risks alongside them. Online banking has created a new risk orientation and even new forms of risk. Technology plays an important role as both a source and a tool for risk control. The purpose of this research is to identify the security situation of the e-banking application and to analyze the risks and attacks that could occur to the customers that, although it’s an e-banking application attacks could happen. Several mitigations were mentioned to overcome attacks like, access control is to mitigate eavesdropping this means that, restricting access to sensitive data is mandatory. Another way to mitigate is, update and patch which is for SQL injection meaning, it's vital to apply patches and updates when it’s available. These attacks may attack the whole application or target an individual where private information is stolen or changed. This research also shows how to apply several more different protections measures to protect oneself and organization from being targets of cybercrime. </p>
