Security Analysis on “Multi-keyword Searchable Encryption for Smart Grid Edge Computing”

Key Points

• Keyword information is revealed from both the ciphertext and trapdoor, confirming flaws in the encryption scheme.
• The analysis challenges the claim that no keyword information can be extracted during encryption processes.
• Observational analysis of the public key searchable encryption scheme shows weaknesses in confidentiality for encrypted data.
• This findings highlight the need for improved security measures in smart grid edge computing technologies.
