Functional encryption (FE) represents an important advancement beyond traditional public-key encryption since it supports computations on ciphertext without revealing the underlying plaintext. This feature is highly valuable in applications that both require secure storage of information and controlled sharing of information, including cloud storage services. However, the computational intensity of FE schemes presents a major challenge, especially when coherent connectives are supported, leading to execution inefficiency factors. To address this, many proposals suggest that the significant computational tasks should be outsourced to a powerful third-party entity, such as a cloud benefit provider, while keeping the user's tasks minimal. Despite the efficiency gains, the current methods overlook a very important perspective: the requirement for a formalized payment mechanism to reward the mediator for the computational resources consumed. Anticipating cloud administrations to perform seriously computations without an motivating force is unlikely and unsustainable. This work points to the require for a secure and proficient installment system inside useful encryption frameworks, probably by utilizing blockchain-based shrewd contracts to mechanize and secure the remuneration handle. Building up a strong motivation show will improve the common sense of functional encryption in real-world applications, guaranteeing both computational proficiency and financial practicality.
