Question
In the context of asymmetric encryption, which of the
following is a key feature of public-private key pairs?Solution
Asymmetric encryption uses a pair of keys: a public key, shared openly, and a private key, kept confidential. In this system:
- Data encrypted using the private key can be decrypted by the corresponding public key , which is essential for digital signatures. For instance, signing a document with a private key allows recipients to verify its authenticity using the public key.
- Conversely, data encrypted with the public key can only be decrypted with the private key , ensuring secure transmission of sensitive information.
- Option A: While the keys are mathematically related, they are not interchangeable for encryption and decryption.
- Option B: The private key is not solely for encryption; it is often used for decryption or signing.
- Option D: The private key must remain confidential and is never shared between parties.
- Option E: Public-private key pairs are not directly used for hashing, which is a different cryptographic operation.
(15.15 ×  34.98) + 24.15% of 749.99 = ? + 124.34
?% of 549.83 – 18.05 × 31.96 = 44.94% of 479.84 – 13.98 × 33.13Â
16.98 × 88.05 + 1999.996% of 299.08 + 5.005 % of 4999.997 = ? × 20.98 × 40.009
√28561.11  × √ 960.9  – (18.02)2  =? × 4.95Â
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99
What will come in place of the question mark (?) in the following series?
2, 4, 12, 60, 420, ?
181.87 ÷ 13.89 X 8.13 + ? = 11.852Â
