GCP 推出 Cloud HSM (beta)

這算是 Google Cloud Platform 在補產品線,讓那些有強制使用 HSM 的需求的應用 (通常是遇到一定要 FIPS 140-2 的規範) 可以搬上雲端:「Introducing Cloud HSM beta for hardware crypto key security」。

從圖片上可以看到 LiquidSecurity,應該是「LiquidSecurity® General Purpose HSM Adapters and Appliances」這個產品:

如同 AWSCloudHSM 服務,GCP 的 Cloud HSM 也是提供 FIPS 140-2 Level 3:

Cloud HSM allows you to host encryption keys and perform cryptographic operations in FIPS 140-2 Level 3 certified HSMs (shown below).

演算法上,支援 AESRSAECC (NIST 的 P-256 與 P-384):

In addition to symmetric key encryption using AES-256 keys, you can now create various types of asymmetric keys for decryption or signing operations, which means that you can now store your keys used for PKI or code signing in a Google Cloud managed keystore. Specifically, RSA 2048, RSA 3072, RSA 4096, EC P256, and EC P384 keys will be available for signing operations, while RSA 2048, RSA 3072, and RSA 4096 keys will also have the ability to decrypt blocks of data.

目前只支援 us-east1us-west1,另外價錢也比軟體服務版本的 Cloud KMS 貴不少:

不過一般情況應該不會得用 CloudHSM,先有個印象就好...

Cloudflare 測試 ARM 新的伺服器

Cloudflare 測試 ARM 新的伺服器 (是由 QualcommCavium 提供工程樣品給 Cloudflare 測試):「ARM Takes Wing: Qualcomm vs. Intel CPU comparison」。

原文有很多測試數據,可以看出來跟以前比起來好很多。系統程式的效能都還不錯,跟 Intel 平台各有輸贏,但 Go 對 ARM 的最佳化好像不太好,有點慘...

不過這樣至少表示了有機會互拼,如果考慮電力使用情況,加上這還是工程樣板的話,應該是可以拉板凳了?
