Secure a Transaction Activity with Base64 Algorithm and Word Auto Key Encryption Algorithm

A Secure and Comparable Text Encryption Algorithm

This paper discloses a simple algorithm for encrypting text messages, based on the NP-completeness of the subset sum problem, such that the similarity between encryptions is roughly proportional to the semantic similarity between their generating messages. This allows parties to compare encrypted messages for semantic overlap without trusting an intermediary and might be applied, for example, a...

A New Fast Data Encryption Algorithm (FDE)

a cca2-secure incomparable public key encryption scheme

in 2003, waters, felten and sahai introduced a novel cryptographic primitive called incomparable public key cryptosystem to protect anonymity of message receivers in an untrusted network. in this setting, a receiver is allowed to create many anonymous identities for himself without divulging the fact that all these identities refer to the same receiver. recently, lee and lim improved the soluti...

Secure Hashing Algorithm and Advance Encryption Algorithm in Cloud Computing

Cloud computing is one of the most sharp and important movement in various computing technologies. It provides flexibility to users, cost effectiveness, location independence, easy maintenance, enables multitenancy, drastic performance improvements, and increased productivity. On the other hand, there are also major issues like security. Being a common server, security for a cloud is a major is...
