Data sharing is a method that allows users to legally access data over the cloud. Cloud computing architecture is used to enable the data sharing capabilities only to the authorized users from the data stored in the cloud server. In the cloud, the number of users is extremely large and the users connect and leave randomly hence that the system needs to protect the data access. Many algorithms have been reviewed but the most challenging issue in cloud computing is a data-sharing system and access policy for an authorized user. A novel technique called Deep Multilayer Percepted Policy Attribute Lamport Certificateless Signcryption (DMPPALCS) is introduced for improving the security level of data access in the cloud with multiple layers. Initially, the users register their details to the cloud server for retrieving the numerous services. After that the cloud server generates the private and public keys for each registered user using Lamport Certificateless Signcryption. After the key generation, the user sends a request to the cloud server for acquiring the data. The cloud server validates that the requested user is authorized or not based on the policy attributes. Then the cloud server facilities the user requested data in the form of ciphertext and generates the signature to the cloud user. Finally, the signature is verified at the user side to decrypt the data. If the signature is valid, then the authorized users obtain the original data and improve secure data access. The proposed DMPPALCS technique is used for evaluating various security parameters.

可以感知的深层多层策略属性Lamport无证书签署加密,可在云中安全地访问和共享数据

数据共享是一种允许用户合法地通过云访问数据的方法。云计算体系结构用于从存储在云服务器中的数据中仅对授权用户启用数据共享功能。在云中,用户数量非常多,并且用户随机连接和离开,因此系统需要保护数据访问。已经审查了许多算法,但是云计算中最具挑战性的问题是数据共享系统和授权用户的访问策略。为了提高多层云中数据访问的安全性,引入了一种称为“深层多层感知策略属性Lamport无证书签名加密”(DMPPALCS)的新技术。最初,用户将其详细信息注册到云服务器以检索众多服务。之后,云服务器使用Lamport无证书签名加密为每个注册用户生成私钥和公钥。密钥生成后,用户向云服务器发送请求以获取数据。云服务器根据策略属性来验证所请求的用户是否已授权。然后,云服务器为用户请求的密文形式的数据提供便利,并向云用户生成签名。最后,在用户端验证签名以解密数据。如果签名有效,则授权用户将获取原始数据并改善安全数据访问。提出的DMPPALCS技术用于评估各种安全参数。密钥生成后,用户向云服务器发送请求以获取数据。云服务器根据策略属性来验证所请求的用户是否已授权。然后,云服务器为用户请求的密文形式的数据提供便利,并向云用户生成签名。最后,在用户端验证签名以解密数据。如果签名有效,则授权用户将获取原始数据并改善安全数据访问。提出的DMPPALCS技术用于评估各种安全参数。密钥生成后,用户向云服务器发送请求以获取数据。云服务器根据策略属性来验证所请求的用户是否已授权。然后,云服务器为用户请求的密文形式的数据提供便利,并向云用户生成签名。最后,在用户端验证签名以解密数据。如果签名有效,则授权用户将获取原始数据并改善安全数据访问。提出的DMPPALCS技术用于评估各种安全参数。然后,云服务器为用户请求的密文形式的数据提供便利,并向云用户生成签名。最后,在用户端验证签名以解密数据。如果签名有效,则授权用户将获取原始数据并改善安全数据访问。提出的DMPPALCS技术用于评估各种安全参数。然后,云服务器为用户请求的密文形式的数据提供便利,并向云用户生成签名。最后,在用户端验证签名以解密数据。如果签名有效,则授权用户将获取原始数据并改善安全数据访问。提出的DMPPALCS技术用于评估各种安全参数。
