Abstract: Data security in the cloud has been a major issue since the inception and adoption of cloud computing. Various frameworks have been proposed, and yet data breaches persist. Since encryption is the dominant method of cloud data security, the advent of quantum computing implies an urgent need to proffer a model that provides adequate data security for both classical and quantum computing. Thus, most cryptosystems will be rendered vulnerable and obsolete, although some cryptosystems will stand the test of quantum computing. The article proposes a model that includes a type of McEliece cryptosystem, which is proposed to replace Rivest-Shamir-Adleman (RSA) in the quantum computing era to secure access control data and implement N-th variables. Degree Truncated Polynomial Ring Units (NTRU) cryptosystem for securing cloud user data. Simulation of the proposed McEliece algorithm shows that the algorithm has better time complexity than the existing McEliece cryptosystem. Furthermore, the novel modification of S and P parameters further improves the security of the proposed algorithms. Moreover, the simulation of the proposed NTRU algorithm revealed that the existing NTRU cryptosystem had better time complexity when combined with the proposed NTRU cryptosystem.
