What are asymmetric keys in cryptography?
Best insight from top research papers
Asymmetric keys in cryptography, also known as public-key cryptography, involve the use of two keys - a public key and a private key . The public key is utilized for encryption, while the private key is used for decryption. Unlike symmetric key cryptography where the same key is used for both encryption and decryption, asymmetric key cryptography employs a matched pair of keys for each user. This method is slower but is well-suited for key management and is central to many real-world cryptographic systems. Various algorithms such as RSA, Diffie-Hellman, ElGamal, and others fall under asymmetric key cryptography, enhancing security by using different keys for encryption and decryption purposes. Asymmetric key algorithms play a crucial role in securely transmitting data and ensuring authentication without the need for parties to agree on a secret key beforehand.

What is the difference between symmetry cell and asymmetry cell?5 answersSymmetric cell division results in two daughter cells with the same fate, while asymmetric cell division produces daughter cells with different fates. Asymmetric division plays a crucial role in generating cell diversity and maintaining stem cell populations. Epigenetic mechanisms are implicated in maintaining or altering cell fate during asymmetric stem cell division, highlighting the importance of asymmetry in influencing cell identity. In biological structures, symmetry and asymmetry are fundamental aspects. While symmetric structures are simpler to encode and may arise more commonly due to random mutations, evolutionary pressures often drive the development of asymmetry in complex structures like the human brain, enhancing multitasking abilities and energy efficiency. Asymmetry in biological membranes, driven by lipid composition differences, influences core biological functions and structural properties.
What are important of Asymmetric carbon carbon bond?5 answersAsymmetric carbon-carbon bond formation is important in various fields. In the field of organic chemistry, it enables the rapid construction of therapeutic small molecules, which is crucial for improving human health. Asymmetric carbonylation reactions, such as asymmetric hydroformylation, are attractive methods for synthesizing chiral compounds on a large scale. Catalytic asymmetric carbon-carbon bond-forming reactions provide efficient ways to synthesize optically active compounds, although their efficiency in terms of turnover number can be a challenge. Solventless asymmetric alkylation in a ball mill has been shown to give amino acid precursors with stereochemical control. Catalytic asymmetric transformations based on carbon-carbon bond cleavages have emerged as versatile strategies for accessing transient organometallic species.
How does monetary policy affect financial stability in an asymmetric manner?5 answersMonetary policy can affect financial stability in an asymmetric manner. One way is through the use of macroprudential interventions in financial markets, which can correct aggregate demand externalities and address wealth distribution effects on output. Another way is through the focus on price stability as the paramount objective of monetary policy, which can promote financial stability by avoiding fluctuations in the rate of inflation. Additionally, the use of macroprudential measures alongside monetary policy can address financial stability risks, with the two instruments working together to achieve the objectives of inflation targeting and maintaining financial stability. The interaction between monetary and financial trilemmas highlights the need for policies that can address the asymmetric effects of monetary policy on financial stability.
How does monetary policy affect financial stability in an asymmetric environment?5 answersMonetary policy has different effects on financial stability in an asymmetric environment. In an economy with asymmetric information between borrowers and lenders, monetary policy affects the cost of external finance, leading to real effects in the flexible-price equilibrium. The natural rate of interest, which is often used as a policy indicator, is not useful in this context as it is itself affected by monetary policy. A generalized definition of the natural rate that is not policy dependent can be used as the intercept of a monetary policy rule to achieve price stability. The impact of monetary policy shocks on house prices also depends on the nature of the shock and local housing supply elasticities. Expansionary monetary policy shocks have a larger impact on house prices in supply-inelastic areas, while contractionary shocks have a greater impact in supply-elastic areas. In an asymmetric environment, the optimal design of monetary policy takes into account structural asymmetries across countries and the heterogeneity of economic structures to achieve welfare gains.
What is asymmetric key encryption for data security and privacy preservation in cloud computingvation in cloud computing?4 answersAsymmetric key encryption is a technique used for data security and privacy preservation in cloud computing. It involves the use of public key cryptography to protect sensitive data. The security key, which is the most critical factor in protecting public key cryptographic data encryption, is not obtained by the server. This approach can be used in Cryptographically Enforced Access Control method, where either symmetric key or asymmetric key mode is used. The use of asymmetric key encryption ensures that the data is securely stored and accessed in the cloud environment, providing better protection levels for key management. It also allows for secure data sharing and efficient storage in the cloud. By using asymmetric key encryption, data owners can have confidence that their private data will not be exposed or mishandled by cloud providers.
Is symmetric encryption more efficient than asymmetric encryption?5 answersSymmetric encryption is generally considered to be more efficient than asymmetric encryption. This is because symmetric encryption requires less computational power and resources compared to asymmetric encryption. In symmetric encryption, the same key is used for both encryption and decryption, which simplifies the process and reduces the computational overhead. On the other hand, asymmetric encryption involves the use of a public key for encryption and a private key for decryption, which requires more computational resources and time. However, it is important to note that while symmetric encryption is more efficient, asymmetric encryption offers additional security benefits such as identity authentication and integrity of encrypted messages. Therefore, the choice between symmetric and asymmetric encryption depends on the specific requirements of the application and the desired balance between efficiency and security.
