Some Implementation Issues for Security Services based on IBE
Identity Based Encryption (IBE) is a public key cryptosystem where a unique identity string, such as an e-mail address, can be used as a public key. IBE is simpler than the traditional PKI since certificates are not needed. An IBE scheme is usually based on pairing of discrete points on elliptic curves. An IBE scheme can also be based on quadratic residuosity. This paper presents an overview of...
متن کاملA Secure Email System Based on Identity Based Encryption ISSN 2319 - 6629
Now a days, email has become the most widely communication way in daily life. The main reason for using email is probably because of the convenience and speed in which it can be transmitted irrespective of geographical distances. To improve security and efficiency of email system, most of the email system adopt PKI and IBE encryption schemes. However, both PKI and IBE encryption schemes have th...

متن کاملCARIBE: Adapting Traditional IBE for the Modern Key-Covetous Appetite
Current issues with mass surveillance and a lack of end-user encryption, coupled with a growing demand for key escrow under legal oversight and certificate authority security concerns, raises the question of the appropriateness of continued general dependency on PKI. Under this context, we examine IdentityBased Encryption (IBE) as an alternative to public-key encryption, contrasting the two in ...
متن کاملPractical Implementation of a Secure Email System Using Certificateless Cryptography and Domain Name System
Email is currently the most widely used communication system in daily life. To improve security and efficiency, most email systems adopt Public Key Infrastructure (PKI) as the mechanism to implement security, but PKI based systems suffer from expensive certificate management and problems in scalability. Identity Based Cryptography (IBC) is another method, but it has the inherent drawback of Key...
