Currently we are witnessing a rapid integration of social networks and cloud computing,
especially on storing social media contents on cloud storage due to its cheap management …

Nowadays, more and more people prefer to outsource their storage to the cloud; however,
due to some accidents, cloud storage service providers may lose some data outsourced by …

In this paper two new ways for efficient secure outsourcing the decryption of key-policy
attribute-based encryption (KP-ABE KP-ABE) with energy efficiency are proposed. Based on …

With the continuous development of the internet of things (IoT) technology, large amount of
data has been generated by lots of IoT devices which require large-scale data processing …

Recently Liang et al. propose an interesting privacy-preserving ciphertext multi-sharing
control for big data storage mechanism, which is based on the cryptographic primitive of …

Nowadays, it is very popular to make friends, share photographs, and exchange news
throughout social networks. Social networks widely expand the area of people's social …

In this paper, we propose a novel way to provide a fully homomorphic encryption service,
namely by using garbled circuits. From a high level perspective, garbled circuits and fully …

In proxy re-encryption (PRE), a proxy with re-encryption keys can transfer aciphertext
computed under Alice's public key into a new one, which can be decrypted by Bob only with …

Network optimisation for improving security and safety level of dangerous goods
transportation (NOISSLDGT) belongs to NP-hard problems with strict constraints, and that …

Cloud computing provides dynamically scalable resources provisioned as a service over
networks. But untrustworthy cloud service provider (CSP) offers a big obstacle for the …
