## 3 Proposed Method
### Magnify Pinpointing-Based Encryption (MPBE)  
Only key creation, encryption, and decryption times are calculated in the suggested method. Currently, network overhead is a problem. This framework shows how user 1 and user 2 can access each other's data by using magnify-pointing-based encryption as a security, authentication, and authorization tool. Both user 1 and user 2, two users who access the cloud's services, are shown in Figure 5 as part of the cloud environment, using the cloud database for access. Role-based classification is faster with identity-based encryption [33]. With these techniques, users are given access to the data after authenticating their identities. This plan is initially put into practice on proxy servers to remove unwanted users. The identities of allowed users are recorded on proxy servers, and whenever an unauthorised user tries to access the server's service, their access is revoked because no key matches that identity. As a result, in order to access the service, each user must register their identification. Security is becoming increasingly in demand as a result of technological advancements like cloud computing. This system is used by several security companies to protect user data and information [34]. Uploading and downloading of data or files is a crucial component of cloud security implementation. The effectiveness of an IBE scheme is also significantly influenced by network congestion and service speed. The Algorithm 2 describes the key generation process. However, in order to improve time efficiency, the suggested method described in Section 3.2 focuses primarily on key creation, encryption, and decryption. The only times that are calculated in the proposed method are those for key generation, encryption, and decryption. At this time, network overhead is compromised. Using IBE as a security, authentication, and authorization tool, this system illustrates how [PERSON] and [PERSON] can access each other's data. An authorised user's identity cannot be obtained by an unauthorised user because PKG stores user identities in Lagrange polynomial equation form, which is computationally challenging for an outsider to decipher and obtain the user's original identity. Because they communicate these identities using secure socket connections (SSL), when [PERSON] sends his identification to [PERSON] in the middle of the network, an attacker cannot obtain the identity. Hash-based key generation techniques are computationally costly; hence, pairing-based key generation techniques are used instead. As mentioned, the demand for security is rising because of technological advancements like cloud computing. This system is used by several security companies to protect user data and information. Uploading and downloading of data or files is a crucial component of cloud security implementation. Let \(G\) stand for a collection of prime order \(p\). Group \(G\) forms an accurate bilinear map onto Group \(G_{1}\). \(G_{1}\)'s bilinear map representation is given by the formula \(e\): \(G\times G_{1}\to G_{2}\)  
Figure 5: Framework for proposed work. where \(g\) is the group G's generator. The group size is determined by a security parameter, and each identity is represented by four strings, each of length \(n.4\). \[SL=(sl_{1},sl_{2},sl_{3},\ldots,sl_{n}). \tag{7}\]  
The \(SL\) bit strings length is utilised to produce fixed length \(n\) bit strings. The suggested magnify pinpointing-based encryption algorithm includes the following phases. 1: Private key generator (PKG) starts the setup process and decides the security parameters like the level of bits and type of curves. 2: [PERSON] obtains the master public key from PKG. 3: [PERSON] authenticate himself by issuing his identity to PKG and receives the private key for encrypting the data. 4: Similarly, [PERSON] obtains the master public key from PKG. 5: [PERSON] authenticate herself by issuing his identity to PKG and receives the private key for encrypting the data.
