Cryptanalysis of Vigenere, AES, and RSA Ciphers

A system that uses biometric data, such as fingerprints or facial features, to recognise users securely while protecting the data against future quantum computer attacks. Fuzzy extractors help turn noisy biometric inputs into stable cryptographic keys.

A research paper that reviews the main technologies used in mobile payments and evaluates how secure and private they are. It compares SMS-based payments with NFC and wallet-based systems, showing that newer systems are more secure but often collect more user data. The paper also explores privacy-focused alternatives such as blockchain and passkey-based models, and suggests that future mobile payment systems should aim for a better balance between strong security and user anonymity.

In the increasingly competitive digital commerce landscape, small to medium-sized businesses (SMBs) face significant challenges in establishing and maintaining a meaningful online retail pres ence. Unlike large retail enterprises, these businesses often lack tools that enable them to manage and optimise an e-commerce platform that can meet ever-evolving customer expectations. Meanwhile, modern consumers demand smooth and fast online shopping experiences, including intuitive product browsing and secure checkout and payment. Failure to meet these standards can often lead to lost sales opportunities and hurts the overall reputation and presence of brands in a highly saturated market. This is further amplified by the operational complexity of providing a technically sound and re sponsive platform that meets these needs. In order to analyse sales trends and respond to customer feedback, many smaller organisations are forced to develop sub-par systems, or rely on platforms such as social media, which are not purpose-built retail solutions. This not only negatively impacts customer experience, but poses a significant security risk as well.
