Enkripsi masukan pelanggan sensitif di Amazon Connect

Anda dapat mengenkripsi data sensitif yang dikumpulkan oleh aliran. Untuk melakukan ini, Anda perlu menggunakan kriptografi kunci publik.

Saat mengonfigurasi Amazon Connect, pertama-tama Anda memberikan kunci publik. Ini adalah kunci yang digunakan saat mengenkripsi data. Kemudian, Anda memberikan sertifikat X.509, yang mencakup tanda tangan yang membuktikan bahwa Anda memiliki kunci pribadi.

Dalam alur yang mengumpulkan data, Anda memberikan sertifikat X.509 untuk mengenkripsi data yang ditangkap menggunakan atribut sistem input pelanggan Tersimpan. Anda harus mengunggah kunci dalam .pem format untuk menggunakan fitur ini. Kunci enkripsi digunakan untuk memverifikasi tanda tangan sertifikat yang digunakan dalam alur.

Untuk mendekripsi data dalam atribut input pelanggan Tersimpan, gunakan Enkripsi. AWS SDK Lihat informasi selengkapnya di Panduan Developer AWS Encryption SDK.
