An information can help in decision making, so it is considered to have a high effectiveness value for the recipient of the information. Information exchange that utilizes public media internet services is widely used, so the validity of information must be done security from unauthorized attacks. One of them uses cryptography. AES is a method used by the National Institute of Standards and Technology (NIST) as a standard for the United States Federal encryption algorithm. Creativity in cryptographic modification can increase the strength of an attack. This study uses AES 128, 192, and 256 bit CBC mode algorithms by conducting trials at the level of encryption, decryption and the appearance of character frequencies. Encryption test results obtained an average speed of 128 bit blocks, namely 14.2 ms, 256 bits 13.2 ms and 192 bits 11.5 ms. While the decryption test results obtained an average speed of 128 bit blocks, namely 13.2 ms, 192 bits 14 ms and 256 bits 16.5 ms. The pattern of occurrence of the average frequency generated by 9%, by accepting symbols and numbers using this algorithm has little to solve by reading the characters display. The validation test produces a value of 100% where the functionality testing shows the expected results.Keyword: Security Information, AES, CBC, AES Mode CBC Abstrak Informasi berasal dari sekumpulan data yang didapatkan dari berbagai sumber yang telah diolah. Sebuah informasi bisa membantu dalam pengambilan keputusan, sehingga dianggap memiliki nilai efektivitas tinggi bagi penerima informasi. Pertukaran informasi yang memanfaatkan layanan publik media internet marak digunakan, maka keabsahan informasi harus dilakukan keamanan dari serangan pihak tidak berwenang. Salah satunya menggunakan kriptografi. AES adalah metode yang dimanfaatkan National Institute of Standards and Technology (NIST) sebagai standar algoritma enkripsi Federal Amerika Serikat. Kreativitas dalam modifikasi kriptografi bisa meningkatkan kekuatan dari serangan. Penelitian ini menggunakan algoritma AES 128, 192, dan 256 bit mode CBC dengan melakukan uji coba pengujian pada tingkat kecepatan proses enkripsi, dekripsi dan kemunculan frekuensi karakter. Hasil uji coba pengujian enkripsi didapatkan tingkat kecepatan rata-rata blok 128 bit yaitu 14,2 ms, 256 bit 13,2 ms dan 192 bit 11,5 ms. Sedangkan hasil uji coba dekripsi didapatkan tingkat kecepatan rata-rata blok 128 bit yaitu 13,2 ms, 192 bit 14 ms dan 256 bit 16,5 ms. Pola kemunculan frekuensi rata-rata dihasilkan 9%, dengan menerima simbol dan angka menunjukan algoritma ini memiliki kemungkinan kecil dapat dipecahkan melalui pembacaan kemunculan karakternya. Pengujian validasi menghasilkan nilai 100% dimana pengujian fungsionalitas menunjukkan hasil yang sesuai diharapkan.
