Program Code – Revocable Data Storage Project in Mobile Clouds – Service Computing

Certainly! Given the fascinating topic of ‘Revocable Attribute-based Data Storage in Mobile Clouds’ which falls into the realm of Service Computing, let’s design a Python program. This program will simulate a simplistic model of an attribute-based storage system, capable of storing, retrieving, and revoking data access based on user attributes in a mobile cloud environment.

For educational and simplicity’s sake, we will assume our ‘cloud’ storage is represented by a Python dictionary, and user attributes will be simulated by another dictionary. Revocation is handled by updating the access control policies, reflecting the real-world scenario where users’ access to data can be dynamically modified based on changes in their attributes or roles.

Without further ado, let the coding saga commence!

class MobileCloudStorage:
    def __init__(self):
        self.data_storage = {}
        self.user_attributes = {}
        self.access_policies = {}

    def upload_data(self, data_id, data_content, access_policy):
        '''Store data with an associated access policy'''
        self.data_storage[data_id] = data_content
        self.access_policies[data_id] = access_policy
        print(f'Data {data_id} uploaded successfully.')

    def update_access_policy(self, data_id, new_access_policy):
        '''Update access policy for existing data'''
        if data_id in self.access_policies:
            self.access_policies[data_id] = new_access_policy
            print(f'Access policy for {data_id} updated successfully.')
        else:
            print(f'Data {data_id} not found.')

    def revoke_access(self, user_id):
        '''Revoke all data access for a user'''
        if user_id in self.user_attributes:
            self.user_attributes[user_id] = []
            print(f'Access revoked for user {user_id}.')
        else:
            print(f'User {user_id} not found.')

    def assign_user_attributes(self, user_id, attributes):
        '''Assign attributes to a user'''
        self.user_attributes[user_id] = attributes
        print(f'User {user_id} attributes updated.')

    def retrieve_data(self, user_id, data_id):
        '''Retrieve data if user has necessary attributes according to access policy'''
        if data_id in self.data_storage and user_id in self.user_attributes:
            necessary_attributes = self.access_policies[data_id]
            user_attributes = self.user_attributes[user_id]
            if all(attr in user_attributes for attr in necessary_attributes):
                print(f'Data retrieved for {data_id}: {self.data_storage[data_id]}')
            else:
                print(f'Access denied for {data_id}.')
        else:
            print(f'Data {data_id} or user {user_id} not found.')

# Sample execution
cloud = MobileCloudStorage()
cloud.upload_data('Document1', 'Top Secret Document', ['Manager', 'HR'])
cloud.assign_user_attributes('Alice', ['Employee'])
cloud.retrieve_data('Alice', 'Document1')  # Should deny access
cloud.assign_user_attributes('Alice', ['Manager'])
cloud.retrieve_data('Alice', 'Document1')  # Should allow access

Expected Code Output:

Data Document1 uploaded successfully.
User Alice attributes updated.
Access denied for Document1.
User Alice attributes updated.
Data retrieved for Document1: Top Secret Document

Code Explanation:

The provided Python program simulates a basic revocable attribute-based data storage system intended for use in mobile cloud environments, resonating with the specified topic.

Architecture and Logic:

1. Initialization: The class MobileCloudStorage encapsulates our storage system. It initializes three dictionaries to simulate cloud data storage (data_storage), user attributes (user_attributes), and data access policies (access_policies).
2. Data Uploading: The method upload_data() allows the storage of data along with an access policy, which is a list of attributes required to access the data.
3. Access Policy Management: Methods update_access_policy() and revoke_access() manage the access control aspect. The former updates the list of attributes needed to access certain data, and the latter revokes all data access for a user by emptying their attribute list.
4. User Attribute Management: The method assign_user_attributes() assigns or updates attributes for a user, determining what data they can access based on the current access policies.
5. Data Retrieval: The method retrieve_data() checks if a user, identified by their user_id, has the necessary attributes to access the requested data. Access is granted if the user’s attributes match the data’s access policy.

This model demonstrates a rudimentary, yet effective, approach to implementing revocable attribute-based data storage in mobile cloud environments, focusing on dynamic access control through attribute management.
