Secure Communication: A Proposed Public Key Watermark System
The idea of e-Commerce is to take advantage of all the possibilities offered by information technology (such as digital communications, multimedia, internet, cell phones, teleconferences, etc.) and to improve the security of various organizations. In the article, the authors focus on securing all the contents of e-Commerce by proposing a public key watermarking algorithm for web content integri...
متن کاملDestroying Steganography via Amalgamation: Kleptographically CPA Secure Public Key Encryption
We describe a general technique to protect randomized algorithms against kleptographic attacks. We then apply the technique to construct the first IND-CPA secure public-key encryption scheme in the kleptographic setting. Our scheme preserves IND-CPA security, even when all relevant cryptographic algorithms—including key generation—are subject to adversarial subversion. The scheme requires no tr...
متن کاملThe Internet public key infrastructure
Long before the advent of electronic systems, different methods of information scrambling were used. Early attempts at data security in electronic computers employed some of the same transformations. Modern secret key cryptography brought much greater security, but eventually proved vulnerable to brute-force attacks. Public key cryptography has now emerged as the core technology for modern comp...
متن کاملTrust and Public Key Infrastructure
In the current rocket-speed growing E-commerce market, certain infrastructure, which enables users to exchange information and money securely over the Internet, is essential. Unfortunately, Internet is mere a cloud of connections of nodes. There is no organization to operate and manage. So the Internet itself is not responsible for any malicious frauds and attacks, and failures caused by reliab...
متن کاملa 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...
