Virus stamping in single cells

Multiple Virus Infection of Single Host Cells

Evidence is presented to show that two or more viruses can simultaneously manifest their characteristic activities within individual epithelial cells of the normal rabbit's cornea. This evidence, together with that previously presented (1, 5, 6), makes plain that multiple virus infection of a single host cell can take place in corneal cells, in the cells of chick embryos, and in those of rabbit...

A Time-stamping Proxy Signature Scheme Using Time-stamping Service

In current proxy signature schemes, an original signer delegates her signing capability to a proxy signer, and then the proxy signer can sign messages on behalf of the original signer. Although these schemes have succeeded in proxy delegations, they share a common problem. That is, a verifier cannot ascertain that a proxy signature was signed by the proxy signer during the valid delegation peri...

Time-Stamping for Malaysia

One of the most promising uses of time-stamping technology lies in combining it with a public key infrastructure. A public-key infrastructure (PKI) consists of protocols, services, and standards supporting applications of public-key cryptography [1]. Public-key cryptography involves the use of a public and private key pair. Data encrypted with a public key can only be decrypted with its related...
