Advancement Through Research
In recent years, investigating techniques for designing multi-user authenticated encryption for backup mechanisms in highly-secure environment were put forward. Existing security and identity-based communication protocols used in group key management to achieve confidentiality, integrity and authentication (CIA) mostly relay on ideal tokens issued to individual entities. Achieving hierarchical authenticated encryption, its verifiability is typically challenging task. To address such challenges, this paper proposes simultaneous congruence based scheme for group authentication where multiple user authentication is required to preserve sensitivity of data. The proposed scheme forms a group secret from multiple entities of the group and used as key ensure CIA features. Moreover, the ideology realized, analysis shows that the proposed scheme solves the key problem with the condition of minimum quorum and ensures authentication verifiability.
