Symmetric Public-Key Encryption [PDF]
, 2007 Public-key encryption would seem to be inherently asymmetric. in that only messages sent to a user can be encrypted using his public key. We demonstrate that the use of interactive protocols for sending encrypted messages enables a symmetric use of public keys; we give cryptographic protocols for the following tasks: 1.

ELLIPTIC CURVES PUBLIC KEY TRAITOR TRACING SCHEME [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2008 In this paper we use the elliptic curves system in the Public Key Traitor Tracing Scheme. The Elliptic Curve points form Abelian group that used in the Public Key Traitor Tracing Scheme.

Public-Key Encryption with Delegated Search [PDF]
, 2011 In public-key setting, Alice encrypts email with public key of Bob, so that only Bob will be able to learn contents of email. Consider scenario when computer of Alice is infected and unbeknown to Alice it also embeds malware into message.

Affine Determinant Programs: A Framework for Obfuscation and Witness Encryption [PDF]
, 2020 An affine determinant program ADP: {0,1}^n → {0,1} is specified by a tuple (A,B_1,...,B_n) of square matrices over F_q and a function Eval: F_q → {0,1}, and evaluated on x \in {0,1}^n by computing Eval(det(A + sum_{i \in [n]} x_i B_i)).

New leakage-resilient CCA-secure public key encryption
Journal of Mathematical Cryptology, 2013 This paper shows a generic method of constructing CCA-secure public key encryption schemes with leakage-resilience on the secret key. It is based on a new kind of universal2 hash proof system which accepts an auxiliary parameter.

A New Technique in Rank Metric Code-Based Encryption
Cryptography, 2018 We propose a rank metric codes based encryption based on the hard problem of rank syndrome decoding problem. We propose a new encryption with a public key matrix by considering the adding of a random distortion matrix over F q m of full column ...
