Dokumen ini menunjukkan cara menggunakan kunci enkripsi yang dikelola pelanggan (CMEK) untuk
mengenkripsi dan mengontrol data dalam penyimpanan di layanan cloud melalui
Cloud Key Management Service. CMEK terintegrasi dengan
penyesuaian kode
Gemini Code Assist tidak mendukung penggunaan kunci
Cloud EKM.
Dalam dokumen ini, Anda akan melakukan hal berikut:
Pelajari cara membuat CMEK.
Berikan izin ke akun layanan Gemini Code Assist.
Buat indeks repositori kode dengan CMEK.
Menghapus akses ke repositori CMEK.
Secara default, Gemini untuk Google Cloud mengenkripsi konten pelanggan dalam penyimpanan. Gemini menangani enkripsi untuk Anda tanpa perlu tindakan tambahan dari Anda. Opsi ini disebut enkripsi default Google.
Jika ingin mengontrol kunci enkripsi, Anda dapat menggunakan kunci enkripsi yang dikelola pelanggan (CMEK) di Cloud KMS dengan layanan yang terintegrasi dengan CMEK, termasuk Gemini. Dengan menggunakan kunci Cloud KMS, Anda dapat mengontrol tingkat perlindungan, lokasi, jadwal rotasi, izin penggunaan dan akses, serta batasan kriptografisnya.
Dengan Cloud KMS, Anda juga dapat melihat log audit dan mengontrol siklus proses kunci.
Alih-alih Google yang memiliki dan mengelola kunci enkripsi kunci (KEK) simetris yang melindungi data Anda, Anda yang mengontrol dan mengelola kunci ini di Cloud KMS.
Setelah Anda menyiapkan resource dengan CMEK, pengalaman mengakses resource Gemini Anda serupa dengan menggunakan enkripsi default Google.
Untuk mengetahui informasi selengkapnya tentang opsi enkripsi, lihat Kunci enkripsi yang dikelola pelanggan (CMEK).
Sebelum memulai
In the Google Cloud console, activate Cloud Shell.
Di lingkungan shell, jalankan
perintah gcloud components update
untuk memastikan Anda telah mengupdate semua komponen gcloud CLI yang diinstal ke versi terbaru. Untuk
langkah ini, Anda dapat menginstal dan melakukan inisialisasi gcloud CLI, atau Anda dapat
menggunakan Cloud Shell.
gcloudcomponentsupdate
Membuat CMEK dan memberikan izin
Untuk membuat CMEK dan memberikan izin akun layanan Gemini Code Assist pada kunci, lakukan tugas berikut:
Di project Google Cloud tempat Anda ingin mengelola kunci, lakukan
tindakan berikut:
Tambahkan akun layanan Gemini Code Assist. Akun layanan adalah service-PROJECT_NUMBER@gcp-sa-cloudaicompanions., dengan PROJECT_NUMBER adalah nomor project dari project Google Cloud tempat Gemini Code Assist diaktifkan.
Sebaiknya batalkan izin dari akun layanan Gemini Code Assist sebelum menonaktifkan atau menghapus kunci. Perubahan pada izin akan diterapkan dalam hitungan detik, sehingga Anda dapat mengamati dampak penonaktifan atau penghancuran kunci.

CMEK is integrated with\n\n[code customization](/gemini/docs/codeassist/code-customization-overview) for\nGemini Code Assist.\nGemini Code Assist doesn't support the use of\n[Cloud EKM](https://cloud.google.com/kms/docs/ekm) keys.\n\nIn this document, you do the following:\n\n- Learn how to create a CMEK.\n- Grant permissions to the Gemini Code Assist service account.\n- Create a code repository index with a CMEK.\n- Remove access to a CMEK repository.\n\nBy default, Gemini for Google Cloud encrypts customer content at\nrest. Gemini handles encryption for you without any\nadditional actions on your part. This option is called *Google default encryption*.\n\nIf you want to control your encryption keys, then you can use customer-managed encryption keys\n(CMEKs) in [Cloud KMS](/kms/docs) with CMEK-integrated services including\nGemini. Using Cloud KMS keys gives you control over their protection\nlevel, location, rotation schedule, usage and access permissions, and cryptographic boundaries.\nUsing Cloud KMS also lets\nyou view audit logs and control key lifecycles.\n\nInstead of Google owning and managing the symmetric\n[key encryption keys (KEKs)](/kms/docs/envelope-encryption#key_encryption_keys) that protect your data, you control and\nmanage these keys in Cloud KMS.\n\nAfter you set up your resources with CMEKs, the experience of accessing your\nGemini resources is similar to using Google default encryption.\nFor more information about your encryption\noptions, see [Customer-managed encryption keys (CMEK)](/kms/docs/cmek).\n\nBefore you begin\n\n1.
