Background: Faculty are encouraged to use a variety of teaching/learning strategies to engage nursing students. While simulation and games are now common, there were no reports in the nursing literature using an "escape room" concept. Escape rooms use an entertainment approach as teams engage in critical thinking to solve puzzles and find clues to escape a room. In the classroom setting, this concept is modified to solve a mystery by finding various objects through a series of puzzles to locate clues. Some of these games involve finding numerical clues to open locks on a box, such as a toolbox. The purpose of this study was to describe the use of a toolbox gaming strategy based on an escape room concept to help students learn about cardiovascular medications in a pharmacology course. Methods: This pilot study employed a descriptive qualitative method to investigate an approach to pharmacology education. The sample consisted of first semester nursing students. Results: Student responses to criteria-based questions resulted in three themes: engaging, teamwork, and frustration, related to using a toolbox scenario strategy as a pathway to learning. Conclusions: This descriptive study yielded mixed results from the students who were frustrated by time constraints but engaged in the learning experience. Lessons are offered for future improvements.

This paper evaluates the current cybersecurity vulnerability of the prolific use of Elliptical Curve Digital Signature Algorithm (ECDSA) cryptography in use by the Bitcoin Core, Ethereum, Bitcoin Cash, and enterprise blockchains such as Multi-Chain and Hyperledger projects Fabric, and Sawtooth Lake. These blockchains are being used in media, health, finance, transportation and government with little understanding, acknowledgment of the risk and no known plans for mitigation and migration to safer public-key cryptography. The second aim is to evaluate ECDSA against the threat of Quantum Computing and propose the most practical National Institute of Standards and Technology (NIST) Post-Quantum Cryptography candidate algorithm lattice-based cryptography countermeasure that can be implemented near-term and provide a basis for a coordinated industrywide lattice-based public-key implementation. Commercial quantum computing research and development is rapid and unpredictable, and it is difficult to predict the arrival of fault-tolerant quantum computing. The current state of covert and classified quantum computing research and advancement is unknown and therefore, it would be a significant risk to blockchain and Internet technologies to delay or wait for the publication of draft standards. Since there are many hurdles Post-Quantum Cryptography (PQC) must overcome for standardisation, coordinated large-scale testing and evaluation should commence promptly.

Hyperledger Fabric (HLF) is a permissioned, blockchain designed by IBM and uses Public Key Infrastructure (PKI), for digital signatures, and digital identities (X.509 certificates), which are critical to the operational security of its network. On 24 January 2019, Aetna, Anthem, Health Care Service Corporation, PNC Bank, and IBM announced a collaboration to establish a blockchain-based ecosystem for the healthcare industry [1]. Quantum computing poses a devastating impact on PKI and estimates of its large-scale commercial arrival should not be underestimated and cannot be predicted. The HIPAA (Health Insurance Portability and Accountability Act) and General Data Protection Regulation (GDPR), requires "reasonable" measures to be taken to protect Protected Health Information (PHI), and Personally Identifiable Information (PII). However, HLF's ecosystem is not post-quantum resistant, and all data that is transmitted over its network is vulnerable to immediate or later decryption by large scale quantum computers. This research presents independent evaluation and testing of the National Institute of Standards and Technology (NIST), based Second Round Candidate Post-Quantum Cryptography (PQC), lattice-based digital signature scheme qTESLA. The second-round submission is much improved, however; its algorithm characteristics and parameters are such that it is unlikely to be a quantum-resistant "as is," pure "plug-and-play" function and replacement for HLF's PKI. This work also proposes that qTESLA's public keys be used to create a quantum-resistant-classical hybrid PKI near-term replacement.
