The paper presents a new unsupervised dimensionality reduction technique, called
parametric t-SNE, that learns a parametric map** between the high-dimensional data …

Proxy signature is a signature scheme that an original signer delegates his/her signing
capability to a proxy signer, and then the proxy signer creates a signature on behalf of the …

A proxy signature scheme permits an entity to delegate its signing rights to another. These
schemes have been suggested for use in numerous applications, particularly in distributed …

In this work we revisit and formally study the notion of proxy cryptography. Intuitively, various
proxy functions allow two cooperating parties F (the “FBI”) and P (the “proxy”) to duplicate …

It is expected that mobile agent will be widely used for electronic commerce as an important
key technology. If a mobile agent can sign a message in a remote server on behalf of a …

We propose a new one-time proxy signature scheme with decoherence-free states. We
analyze its security and show that it is not possible to forge a valid proxy signature even if an …

A trusted monotonic counter is a valuable primitive that enables a wide variety of highly
scalable offline and decentralized applications that would otherwise be prone to replay …

Abstract Identity-based (ID-based) public key cryptosystem can be a good alternative for
certificate-based public key setting, especially when efficient key management and …

This article investigates if and how mobile agents can execute secure electronic transactions
on untrusted hosts. An overview of the security issues of mobile agents is first given. The …

The proxy signature, a variant of the ordinary digital signature, has been an active research
topic in recent years; it has many useful applications, including distributed systems and grid …
