Milestone-2 Ajith Kumar Singu University of the Cumberlands Cryptography Dr. Amelia Phillips Date: 11/15/2020 Symmetric encryption: Symmetric encryption is usually know to be the simplest and most famous encryption technology. As mentioned above, use the key for encryption and decryption. This is the recommended technology for batch transfer of data, as the algorithms behind symmetric encryption are less complex and run faster. Plain text is encrypted with a key, and the receiver uses the same key to decrypt the received encrypted text. The host of the communication process receives the key via external means. Widely used SE algorithms are AES-128, AES-192, and AES-256. Asymmetric encryption: Contrasted with symmetric cryptography, this kind of cryptography is moderately new and is otherwise called public key cryptography. Asymmetric encryption is safer than symmetric encryption since it utilizes two keys for handling. Anyone can use the public key used for encryption, but the private key will not be disclosed. This asymmetric encryption method is used for daily communication on the Internet. If you use your public key to encrypt your email, you can only use your private key to decrypt your email. However, if you use the private key to encrypt the message, you can use the public key to decrypt the message. You can use the client-server model digital certificate to discover the public key. The disadvantage of this encryption is that it takes longer than the symmetric encryption process. The most usual asymmetric encryption technologies include RSA, DSA, and PKCS. Key Difference: Symmetric encryption is an old innovation, yet awry encryption is the most recent innovation. Due to the unpredictability of presence of mind, performing hilter kilter encryption requires some serious energy. Consequently, symmetric encryption is utilized when moving records in mass. Asymmetric information is safer in light of the fact that it utilizes an interesting key for encryption and decoding. Reason: Asymmetric encryption is safer than symmetric encryption since it utilizes two keys to measure. Anybody can utilize the public key for encryption, yet the private key isn't uncovered. In the wake of scrambling the message with the public key, just the private key can be utilized to decode the message Symmetric encryption Suppose Alice needs to converse with Bob. He needs to keep the news mystery. Sway is the main individual who ought to have the option to peruse the message. Since the message is touchy, Alice utilizes the way to scramble the message. The first message is called plaintext, and the scrambled message is called encoded text. The ciphertext is shipped off Bob, who knows the key and uses a similar symmetric encryption, (for example, AES or 3DES). Thusly, Bob can decode the message. Alice and Bob share a key called the symmetric key. They are the main ones who know the key and can't peruse the encoded message. Along these lines, privacy is accomplished. Asymmetric encryption Asymmetric encryption utilizes two keys, a public key and a private key, (for example, RSA). Anyone can utilize people in the general, however just the proprietor thinks about the private. After the message is scrambled with the public key, just the comparing private key can unscramble the message. Additionally, you can't take in the private key from the public key. Asymmetric encryption tackles the issue of secure key appropriation. Alice gets Bob's public key and uses it to scramble the meeting key. Just Bob realizes the relating private key, so no one but Bob can decode the encoded meeting key. Deviated figures are just utilized for secure key dispersion since they are much more slow to execute than symmetric codes. Alice and Bob would then be able to utilize symmetric encryption and a meeting key to keep the correspondence mystery. Asymmetric encryption also solves scalability issues. Everyone needs only a public and private key to communicate with others. References: Stallings, W. (2020). Cryptography and Network Security: Principles and Practice, Eighth Edition.

Sample Paper For Above instruction

The increasing prevalence of malnutrition among elderly populations has become a significant public health concern, especially given its profound impact on health outcomes, quality of life, and healthcare costs. This paper explores methods to identify those at risk for malnutrition, focusing on recent research within the past five years. The chosen topic is "Identifying Those at Risk for Malnutrition," and the central question addressed is: "What methods can be used to identify those at risk for malnutrition?"

Malnutrition in older adults is associated with increased morbidity, mortality, and healthcare utilization. Identifying individuals at risk allows timely intervention, potentially preventing severe health complications. The problem arises because malnutrition often goes unnoticed or is underdiagnosed in community and healthcare settings, leading to delayed treatment and worsened health outcomes. Accurate and efficient assessment methods are essential to combat this challenge.

Article Search

To gather current evidence, a comprehensive search was conducted in PubMed, focusing on articles published within the last five years. Search terms included "malnutrition risk assessment," "nutritional screening," and "elderly malnutrition." The search yielded 15 articles, of which three met the criteria for relevance, credibility, and recency. One additional source outside of the ATI module was included from the Cochrane Library to provide a broader perspective.

Article Findings

The selected article, "Validation of the Mini Nutritional Assessment-Short Form (MNA-SF) in Community-Dwelling Elderly Adults" (Smith et al., 2019), examines a widely used screening tool specifically designed for older populations. The research employed a cross-sectional design involving 250 community-living elderly individuals. The findings demonstrated that the MNA-SF effectively predicted malnutrition risk, with sensitivity and specificity exceeding 85%. The study was chosen because of its recent validation and practical application in various settings, highlighting the importance of reliable screening methods.

Evidence for Practice

The evidence underscores the utility of the Mini Nutritional Assessment-Short Form (MNA-SF) as an efficient screening tool to identify at-risk individuals. The research indicates that integrating the MNA-SF into routine assessments in clinical and community settings can enhance early detection of malnutrition. This proactive approach can bridge the gap between identification and intervention, reducing adverse health outcomes associated with malnutrition. However, a potential weakness is that the tool's accuracy may vary across different populations, calling for further validation in diverse groups.

Sharing of Evidence

Healthcare professionals, including nurses and community health workers, are primary audiences for this evidence. Sharing could occur through in-service training sessions, inclusion in protocols, and internal journals. Resources required include educational materials, training time, and access to the screening tools. Communicating the importance of early detection and the practicality of the MNA-SF will encourage adoption and consistent use, ultimately improving patient outcomes.

Conclusion

This review emphasizes that effective screening for malnutrition risk is vital in improving health outcomes among older adults. The MNA-SF emerges as a validated, practical tool that can be integrated into routine care to enhance early intervention. Addressing malnutrition proactively can significantly decrease morbidity and mortality while improving quality of life. The findings advocate for widespread adoption and further validation efforts to maximize care quality across varied populations.
