Survey on Identity based and Hierarchical Identity based Encryption Schemes
In this paper, we present a comprehensive picture and the state of the art of Identity Based Cryptography (IBC) and their security implications with applications. First, we introduce the basic concepts of security and principles of cryptography and then move into identity-based cryptography, an overview of its development process and research progress. We explain identity-based encryption (IBE)...
متن کاملToward Hierarchical Identity-Based Encryption
We introduce the concept of hierarchical identity-based encryption (HIBE) schemes, give precise definitions of their security and mention some applications. A two-level HIBE (2-HIBE) scheme consists of a root private key generator (PKG), domain PKGs and users, all of which are associated with primitive IDs (PIDs) that are arbitrary strings. A user’s public key consists of their PID and their do...
متن کاملArgument on biometrics identity-based encryption schemes
Recently, a few biometric identity-based encryption (BIO-IBE) schemes have been proposed. BIO-IBE leverages both fuzzy extractor and Lagrange polynomial to extract biometric feature as a user public key and as a preventive measure of collusion attack, respectively. In this paper, we reveal that BIO-IBE is not realistic whereby a query of fresh biometrics is needed for each encryption process. M...
متن کاملIdentity Based Group Signatures from Hierarchical Identity-Based Encryption
A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based on the Naor transformation of a identity-based signature out of an identity-based encryption, adjusted to hierarchical identity-based encryption. We identify sufficient conditions on the underlying HIBE so that the sch...
متن کاملconstructing gender identity through narratives based on hallidays metafunctions
هویت, شکل دادن و بازنمایی آن در گفتمان, توجه بسیاری از محققان این رشته را به خود جلب کرده است. تحقیق حاضر بر شکل دادن به هویت جنسیتی هشت تن از دانشجویان ایرانی مشغول به تحصیل در دوره کارشناسی ارشد از طریق بررسی روایات آنان از تجربیات شخصی, متمرکز شده است. تحلیل داده ها در این تحقیق مشتمل بر سه بخش است: بخش اول شامل کدگذاری موضوعی روایات است که بر اساس آن هویت جنسیتی شرکت کنندگان در تحقیق بر اسا...
