On November 11, 2020, nCipher, which implements digital security measures such as encryption technology, is a public key authentication infrastructure (PKI) that is the key to cyber attack countermeasures in the development of digital applications such as the cloud and IoT (Internet of Things). ) Has been released. The report showed that the number of companies using PKI has increased rapidly worldwide in recent years, and the security trends in Japan among them.

PKI is a mechanism that realizes mutual personal authentication between users in a digital space by using public key cryptography. In addition to e-mail and VPN (Virtual Private Network), it is an important technology to ensure high reliability and accuracy in advancing the development of various systems and applications that utilize the cloud and IoT.
When asked about the purpose of using PKI in each company, the number of respondents who answered "public cloud-based applications" and "user authentication by companies through applications" increased significantly compared to the survey in 2019. Specifically, "public cloud-based applications" increased from 55% to 82%, and "user authentication by companies through applications" increased from 51% to 70%. Regarding this, Mr. Shindou said, "It has been suggested that using PKI is no longer essential in cloud-based application development. Also, in the previously widely used PKI applications such as email and VPN, It is expected that the number of use cases will increase with the increase in remote work. "
