<![CDATA[El-gamal algorithm has two keys, namely public key and secret key. This algorithm has security that lies in the difficulty in calculating discrete algorithms. Both encryption and decryption keys are integers. El-gamal algorithm type asymmetric cryptography algorithm consists of two keys namely public key to encrypt while private key to decrypt. In El-gamal algorithms, distributed keys are public keys that are not required confidentiality while private keys remain stored or not distributed. Anyone who has a public key can do the encryption process but the result of that encryption can only be read by the person who has the private key. To increase the strength of the algorithm, the key used to perform the encryption and decryption process will be modified first using the randomization algorithm that is Karger Min Cut Algorithm. Karger Min Cut algorithm is a probabilistic random algorithm used to verify matrix multiplication. The purpose of using Kargers Min Cut algorithm is to make the resulting key more difficult to guess, making it difficult to read the message or information]]>

<![CDATA[In today's era, renewal is continuously carried out in order to achieve better integrity. The issuance of certificates, which are usually printed on paper, is considered to be prone to damage and loss. Along with the times, certificates are now also issued in digital form. So many people switch to using certificates in digital form. So a mechanism is needed to help secure the certificate. Digital certificates can only be issued by authorized parties. Then the competent authority issues a certificate to another person who has the right to the certificate. Of course, the authenticity of the certificate information has been secured first through the checksum function so that the message in it is encrypted. In cryptography there are many methods and algorithms that can be used, one of which is the Fletcher checksum algorithm. The aim of Fletcher is to provide error detection properties that approximate cyclic redundancy checking but with lower computational effort associated with the summation technique. So that digital certificates that have changed will be detected as authentic.]]>

<![CDATA[Technological developments and human lifestyles allow access to information systems in new ways, for example using online conversations (chat) via an internet connection, which is often in the form of text communication (text chat) or voice (voice chat). Instant messaging only became popular when the internet began to be widely used in the mid-1990s. Along with the human need for easy and fast communication, the application that can be used is Voice Chat which allows users to carry out voice communication. But the voice chat application is less secure because it is easily intercepted by other parties. Eavesdroppers can easily find out the contents of conversations in instant messaging and the lack of privacy for chat users. The RC4 algorithm has a weakness in its use to encrypt a message. The downside is that Vigenere can only perform encryption and decryption processes for short messages. One way that can be used is to make security for the voice chat application using the Mid-Square Technique algorithm]]>

<![CDATA[Mini Market Hidayah (MM Hidayah) is a cooperative company engaged in sembako. So far MM Hidayah has evaluated the performance of its employees on things that are growing only, but has never done the best employee selection. Therefore, a computerized system is needed that can provide convenience in determining the best employees. Therefore, a computerized system is needed that can provide convenience in determining the best employees. In this study proposed a computerized system that can help in the selection of the best employees, namely using profile matching methods and weighted product methods. The Profile Matching method is the process of comparing or matching profiles between individual competencies into the ideal variable predictor level competencies that must be met by the subjects studied. While Weighted Product uses multiplication to connect attribute ratings, where the rating of each attribute must be raised first with the weight of the attribute in question, the process is the same as normalization. The Profile Matching method is used for combat values while weigthed product to determine weighting criteria. If the decision-making process is assisted by a computerized decision support system, it is expected that subjectivity in decision making can be reduced and replaced by the implementation of assessment criteria for all employees.]]>
