With the spread of fast mobile Internet connections, such as 3G and LTE and the increasing processor power of mobile devices accessing cloud computing services on-the-go is common among all users. Sharing private information with friends and family members are options of popular cloud services, such as storage and social media services. But recent headlines(More)
Attribute-based encryption (ABE) allows users to encrypt (cloud) data with fine-grained Boolean access control policies. To be able to decrypt the ciphertext, users need to have a private key with the associated attributes. If the attributes satisfy the formula, the plaintext can be recovered. In this paper, ABE is extended with dynamic attributes. This(More)
The advent of new cryptographic methods in recent years also includes schemes related to functional encryption. Within these schemes Attribute-based Encryption (ABE) became the most popular, including ciphertext-policy and key-policy ABE. ABE and related schemes are widely discussed within the mathematical community. Unfortunately, there are only a few(More)
