KRIPTOSISTEM BERBASIS BLOCKCHAIN UNTUK BERBAGI DATA TERPECAYA DALAM SISTEM INFORMASI CLOUD

2023-08-01T08:08:29+00:00

Sistem informasi Cloud telah menjadi elemen penting dalam lingkungan bisnis dan organisasi modern, memfasilitasi kerjasama dan berbagi data di antara berbagai entitas. Namun, masalah kepercayaan dan keamanan data tetap menjadi perhatian utama dalam lingkungan berbagi informasi yang semakin terdesentralisasi ini. Untuk mengatasi tantangan ini, penelitian ini menyajikan pendekatan baru menggunakan kriptosistem berbasis blockchain untuk menciptakan lingkungan berbagi data yang terpercaya dan aman dalam sistem informasi Cloud . Penelitian ini berfokus pada penggunaan teknologi blockchain yang mendasari kriptosistem, yang menawarkan keamanan yang kuat dan mekanisme kepercayaan yang terdesentralisasi. Dalam lingkup sistem informasi awan kolaboratif, data-data sensitif dan penting dapat dienkripsi dan didistribusikan menggunakan kriptografi asimetris dan teknik hash yang kuat. Data-data ini kemudian diimpor ke dalam rantai blok yang terdesentralisasi, memastikan integritas dan keterlacakan data di seluruh jaringan.Penerapan kriptosistem berbasis blockchain dalam sistem informasi awan kolaboratif memberikan keuntungan dalam hal privasi, keamanan, dan kepercayaan. Data-data sensitif hanya dapat diakses oleh pihak yang memiliki kunci dekripsi yang sesuai, dan tidak lagi memerlukan kepercayaan pada pihak ketiga sebagai otoritas pusat. Dalam konteks ini, penelitian ini juga mengusulkan mekanisme manajemen kunci yang efisien dan aman untuk memastikan distribusi kunci yang tepat dan pengelolaan kunci yang andal.

PENGARUH KUALITAS SISTEM DAN KUALITAS INFORMASI TERHADAP KINERJA DI ASTON INN GIDEON BATAM

This research aims to investigate the influence of system quality and information quality on performance at Aston Inn Gideon Batam. This research employs a quantitative approach with data collection through questionnaires distributed to respondents directly involved in the use of information systems at Aston Inn Gideon Batam. The coefficient determination test results in this study reached 0.943 or 94.3%, indicating that the quality of the system and information variables contribute by 94.3% to employee performance at Hotel Aston Inn Gideon Batam. The multiple regression test results show a constant value of 1,900, indicating that if independent variables (X1 and X2) are constant, the employee performance value will be 1,900. The regression coefficient for system quality (X1) is 0.813, indicating that an increase of one unit in the system quality variable (X1) will increase employee performance (Y) by 0.499 units, meaning that higher system quality corresponds to higher employee performance. The regression coefficient for information quality (X2) is 0.665, indicating that an increase of one unit in the information quality variable (X2) will increase employee performance (Y) by 0.665 units. Simultaneous test results show an F value of 465.904 with a significance level of 0.000, which is less than 0.05. Therefore, F value > F table (465.904 > 3.11), indicating that collectively, the system quality and information quality variables have a positive and significant impact on employee performance.

Analisis Tingkat Kompleksitas Waktu dan Tingkat Keamanan Enkripsi Pada Algoritma Kriptografi RSA, DES, AES

In today's era of advanced information and technology, data plays an important role. However, the importance of data also brings challenges in terms of security and privacy. Cryptography is an effective solution to maintain data security by encoding information so that only authorized parties can read it. This research aims to compare cryptography algorithms such as RSA, DES, AES. This comparison will give an idea about the security level of each algorithm in various situations. RSA is a strong public key cryptography algorithm, using large number factorization for its security. RSA encryption requires O(n^k) time complexity, where n is the number of bits in the public key and k corresponds to the factorization algorithm. The longer the key, the higher the security level, but the encryption process can be slower. DES is a symmetric key cryptography algorithm with 64-bit blocks and O(1) time complexity in the encryption process. However, the relatively short key length makes DES vulnerable to brute-force attacks. AES is a symmetric key cryptography algorithm with 128-bit blocks and 128-bit keys. The AES encryption process has O(1) time complexity, offers better security with longer key sizes and complex structures, and reduces the risk of brute-force attacks. AES is a highly secure and efficient encryption algorithm for maintaining data confidentiality and integrity.
