In this paper, we present a novel framework for the generic construction of biometric Identity Based Encryption (IBE) schemes, which do not require bilinear pairings and result in more efficient schemes than existing fuzzy IBE systems implemented for biometric identities. Also, we analyze the security properties that are specific to biometric IBE namely anonymity and identity privacy. Consideri...

In this article, we introduce four fuzzy relations and the composition, and some useful properties are shown by them. In section 2, the definition of converse relation R of fuzzy relation R and properties concerning it are described. In the next section, we define the composition of the fuzzy relation and show some properties. In the final section we describe the identity relation, the universe...

Recently, Sarier [1] proposed an efficient biometric Identity Based Encryption (IBE) scheme called BIO-IBE using the Sakai Kasahara Key Construction and prove its security in the random oracle model based on the well-exploited k-BDHI computational problem. Despite its efficiency compared to other fuzzy IBE systems implemented for biometric identities, BIO-IBE is not secure against a new type of...

An AG-groupoid is a non-associative algebraic structure mid way between a groupoid and a commutative semigroup. The left identity in an AGgroupoid if exists is unique [9]. An AG-groupoid is non-associative and non-commutative algebraic structure, nevertheless, it posses many interesting properties which we usually find in associative and commutative algebraic structures. An AG-groupoid with rig...

Presented is a completeness theorem for fuzzy equational logic with truth values in a complete residuated lattice: Given a fuzzy set Σ of identities and an identity p ≈ q, the degree to which p ≈ q syntactically follows (is provable) from Σ equals the degree to which p ≈ q semantically follows from Σ. Pavelka style generalization of well-known Birkhoff’s theorem is therefore established.

Fuzzy identity-based encryption (FIBE) has found many applications, such as biometric-based encryption, since its notion was firstly proposed by Sahai and Waters [15]. In this paper, we show how to minimize the damage of secret key exposure in FIBE. We introduce a new notion which we call fuzzy identity-based key-insulated encryption (FIBKIE). In FIB-KIE, the secret key associated with an ident...
