Enhancing Efficiency for ABE Through Homomorphic Encryption in Cryptography

摘要

In today's computer networking technology, most of people stored their confidential data on trusted third-party server. But along with this, data privacy also arises as number of users becomes large. Naturally people want their data only accessible to authorized users according to their access policies. But when using these services, servers may get compromised by an attack like Denial-of-service, chosen cipher-text attack or Denial of service attack. Hence it is still most difficult job in cryptosystem to provide the leveled trustworthy servers and efficient data privacy systems to keep users data under the safe zone. To solve this problem advanced cryptographic methods are needed to be apply to increase efficiency for data encryption as well as to maintain the improved privacy preserving environment on web to share data. Considering these all aspects about privacy in communication, we need to look after the successful implementation also hence we have presented this paper to put forward the ideas of homomorphism into ABE which will truly build an improved as well as trustworthy privacy preserving possible outcomes using homomorphic encryption in the field of cryptography.
