newly shared data. To achieve this, we introduce the concept of Revocable-Storage Identity-Based Encryption (RS-IBE), which

ensures both forward and backward security by incorporating user revocation and cipher text updates.

We further present a concrete RS-IBE construction and validate its security within a defined model. Performance comparisons

highlight the scheme's advantages in functionality and efficiency, making it a viable and cost-effective solution for secure data

sharing. Additionally, implementation results showcase its practical applicability. The RS-IBE scheme is proven to be adaptively

secure under the decisional ℓ-DBHE assumption in the standard model. Comparative analysis confirms that our approach is

efficient and functional, making it suitable for real-world applications.

enables encryption based on user identities, ensuring controlled access. However, traditional IBE lacks a mechanism to revoke

access dynamically. In practical scenarios, users may lose authorization due to changes in roles or security threats. Without a

proper revocation system, former users may still retrieve previously or newly shared data, compromising confidentiality. To

address this issue, we introduce Revocable-Storage Identity-Based Encryption (RS-IBE), which incorporates user revocation and

cipher text updates to provide forward and backward security. This ensures that revoked users are unable to access past or future

encrypted data. Our proposed RS-IBE model is designed to enhance security in cloud-based data sharing, offering a practical,

efficient, and scalable solution. Through security analysis and implementation, we demonstrate its effectiveness in real-world

applications.With the rapid advancement of cloud computing, organizations and individuals increasingly rely on cloud-based

solutions for efficient data storage and sharing. Cloud platforms offer scalability, cost-effectiveness, and accessibility, making

them ideal for various applications, including healthcare, enterprise data management.

When a user’s authorization expires or is revoked, they should no longer have access to previously or newly shared data. To

address this challenge, we introduce Revocable-Storage Identity-Based Encryption (RS-IBE), a cryptographic framework that

integrates user revocation and ciphertext updates to ensure forward and backward security. This means that revoked users cannot

decrypt either past or future encrypted data, enhancing overall security. The proposed RS-IBE model is designed to meet the

demands of modern cloud-based systems, providing efficient key management, adaptive security, and access control policies.

Through theoretical analysis and practical implementation, we demonstrate that RS-IBE enhances data security, privacy

protection, and secure data-sharing mechanisms, making it a viable solution for cloud computing environments.

simplifies key management, it lacks an efficient mechanism for user revocation, making it unsuitable for dynamic cloud

environments. To overcome this challenge, researchers have proposed Revocable Identity-Based Encryption (RIBE) schemes,

which integrate revocation mechanisms into IBE. Boneh and Franklin introduced IBE with key revocation, where a trusted

authority updates user keys periodically. However, this approach increases the computational overhead, making it impractical for

large-scale cloud systems. Later, fuzzy IBE and hierarchical IBE models were developed to improve flexibility, but they still

required frequent key updates. In addition to encryption-based access control, various works have explored attribute-based

encryption (ABE) for fine-grained data access in cloud storage. ABE enables data owners to define access policies based on

attributes rather than user identities, allowing more flexible control. However, ABE schemes also face revocation challenges,

requiring computationally expensive re-encryption processes. To address these issues, the concept of Revocable-Storage Identity-

Based Encryption (RS-IBE) was introduced to provide both forward and backward security by revoking unauthorized users and

security threats, such kind of identity-based access control placed on the shared data should meet the following security goals:

Data confidentiality: Unauthorized users should be prevented from accessing the plaintext of the shared data stored in the

storage server. In addition, the storage server, which is supposed to be honest but curious, should also be deterred from knowing

plaintext of the shared data.

Backward secrecy: Backward secrecy means that, when a user’s authorization is expired, or a user’s secret key is compromised,

he/she should be prevented from accessing the plaintext of the subsequently shared data that are still encrypted under his/her

identity.

Forward secrecy: Forward secrecy means that, when a user’s authority is expired, or a user’s secret key is compromised, he/she

should be prevented from accessing the plaintext of the shared data that can be previously accessed by him/her. Cloud computing

brings great convenience for people. Particularly, it perfectly matches the increased need of sharing data over the Internet. To

Data Owner: The data owner is responsible for managing files within the system. They must first register with a unique

username and password. Upon successful registration, the data owner can log in and access the storage platform. From their

dashboard, they can upload files to the cloud server, where the files are stored in an encrypted format for security. The data owner

has the ability to view the list of uploaded files and modify them while ensuring encryption is maintained.

The administrator can log in to the admin panel and access information about uploaded files, data owners, data users, and revoked

users. If a user has been revoked due to security concerns, the admin has the ability to reinstate their access by un-revoking them,

restoring their permissions.

Key Authority: The key authority is responsible for generating encryption keys for uploaded files. When a data user requests

access to a file, the key authority verifies the request, checking details such as the data owner’s name, file name, and requester’s

information If the request is valid, the key authority generates a unique key and securely transmits it to the respective data user,

enabling them to access the file.

Data User: A data user must register in the system before gaining access. Once registered, they can log in and request files

user, including the file they attempted to access. After verifying that the user was not engaging in malicious activity, the admin

can reinstate their access. Once unrevoked, the user regains full access to the system and its features.

System Implementation:

The implementation phase is where the theoretical design of a project is transformed into a fully functional system. This stage is

crucial for ensuring the success of the new system and instilling confidence in users regarding its effectiveness and reliability. A

well-structured implementation process requires careful planning, an assessment of the existing system, and an understanding of

any constraints that might impact deployment. It also involves designing appropriate strategies for a smooth transition and

evaluating different changeover approaches to minimize risks. During implementation, the focus is on deploying the system into

actual operation, which includes user training, site preparation, and data migration. A key consideration is ensuring that the

transition does not disrupt the organization's ongoing activities, allowing for seamless integration of the new system.

On the off chance that the cloud specialist organization, changes the substance of the cloud, it will be recognized amid the

been popularly used by many organizations to mitigate disaster recovery and to increase the flexibility for the user. The data

redistributed information in an untrusted server without recovering the whole document from the cloud server or having a

duplicate of the information. Personality Based Encryption (IBE) and other PDP plans are utilized for its execution. To actualize

PDP (provable Data Possession) in confirming the uprightness of the redistributed information we use HMAC (Hashed Message

Authentication Code). A message digest is produced utilizing HMAC with the mix of a mystery key. A mystery key is produced
