Heterogeneous Signcryption Scheme Supporting Equality Test from PKI to CLC toward IoT

Transactions on Emerging Telecommunications Technologies, 2020
The prosperity of Internet of Things (IoT) has brought numerous advantages to individuals and organizations. Since the transmission channel is usually considered as untrusted, the notion of signcryption seems to be the desired method to ease the defect ...

Testing variance equality with randmization tests

Journal of Statistical Computation and Simulation, 1989
A simulation experiment was conducted to explore the operating characteristics of randomization tests for testing the equality of two population variances. The F test, and adjusted testing procedure suggested by Box and Andersen (1955) were also included in this study.

Testing equality of modified Sharpe ratios

Finance Research Letters, 2014
The modified Sharpe ratio is commonly used to evaluate the risk-adjusted performance of an investment with non-normal returns, such as hedge funds. In this note, a test for equality of modified Sharpe ratios of two investments is developed. A simulation study demonstrates the good size and power properties of the test.

Group public key encryption with equality test against offline message recovery attack

Information Sciences, 2020
Public key encryption with equality test (PKEET) allows a tester to check whether two ciphertexts encrypted under different public keys contain the same message without decrypting them.

On set equality-testing

1994
This paper is concerned with data structures for representing an arbitrary number of sets of keys such that we can update the sets dynamically, query the membership of a set, and test whether two sets are equal. Such data structures have been studied intensively by a number of researchers [2, 6, 4, 5, 7]. Prior to our work, the best scheme supports set

Lattice-based IBE with Equality Test Supporting Flexible Authorization in the Standard Model

International Conference on Cryptology in India, 2020
Identity-based encryption with equality test supporting flexible authorization (IBEET-FA) allows the equality test of underlying messages of two ciphertexts while strengthens privacy protection by allowing users (identities) to control the comparison of ...
