Shared Key atau WEP (Wired Equivalent Privacy) adalah suatu metoda pengamanan jaringan nirkabel, disebut juga dengan Shared Key Authentication. Shared Key Authentication adalah metoda otentikasi yang membutuhkan penggunaan WEP. Enkripsi WEP menggunakan kunci yang dimasukkan (oleh administrator) ke client maupun access point. Kunci ini harus cocok dari yang diberikan akses point ke client, dengan yang dimasukkan client untuk authentikasi menuju access point.
Proses Shared Key Authentication:
Menurut Arief Hamdani Gunawan, Komunikasi Data via IEEE 802.11, Shared Key Authentication kelihatannya lebih aman dari dari pada Open System Authentication, namun pada kenyataannya tidak. Shared Key malah membuka pintu bagi penyusup atau cracker. Penting untuk dimengerti dua jalan yang digunakan oleh WEP. WEP bisa digunakan untuk memverifikasi identitas client selama proses shared key dari authentikasi, tapi juga bisa digunakan untuk men-dekripsi data yang dikirimkan oleh client melalui access point.
client meminta asosiasi ke access point, langkah ini sama seperti Open System Authentication.
access point mengirimkan text challenge ke client secara transparan.
client akan memberikan respon dengan mengenkripsi text challenge dengan menggunakan kunci WEP dan mengirimkan kembali ke access point.
access point memberi respon atas tanggapan client, akses point akan melakukan decrypt terhadap respon enkripsi dari client untuk melakukan verifikasi bahwa text challenge dienkripsi dengan menggunakan WEP key yang sesuai. Pada proses ini, access point akan menentukan apakah client sudah memberikan kunci WEP yang sesuai. Apabila kunci WEP yang diberikan oleh client sudah benar, maka access point akan merespon positif dan langsung meng-authentikasi client. Namun bila kunci WEP yang dimasukkan client adalah salah, maka access point akan merespon negatif dan client tidak akan diberi authentikasi. Dengan demikian, client tidak akan terauthentikasi dan tidak terasosiasi.
