Abstract: According to examples, an apparatus may include a security enclosure, a main processor housed in the security enclosure, and a physical security monitoring control unit (PSMCU) processor housed in the security enclosure. The PSMCU processor may cause the apparatus to switchably operate between a first mode and a second mode. In the first mode, the PSMCU processor may allow access by the main processor to a first cryptographic key while preventing access by the main processor to a second cryptographic key. In addition, in the second mode, the PSMCU processor may allow access by the main processor to the second cryptographic key while preventing access by the main processor to the first cryptographic key.

Abstract: Examples disclosed herein relate to generating communities on a security information sharing platform. Some examples may enable identifying a set of community attributes to be used to generate a community on the security information sharing platform that enables sharing of security information among a plurality of communities. Some examples may enable authorizing a first user to access community-based security information of the community where the first user is associated a set of user attributes that satisfy the set of community attributes. A security indicator may be obtained from the first user of the community. Information related to the security indicator may be obtained from a second user of the community. Some examples may enable including the security indicator and the information related to the security indicator in the community-based security information of the community.

Abstract: A technique includes performing a plurality of instances of retrieving components of a security key from a plurality of locations of an electronic device and constructing the security key from the components. The technique includes inhibiting electromagnetic field-based eavesdropping from being used to reveal the security key, where the inhibiting includes varying a protocol that is used to retrieve the components among the instances.

Abstract: Examples disclosed herein relate to encryption of community-based security information. Some examples may enable authorizing a user of a community to access an encrypted data item (e.g., at least an encrypted portion of community-based security information of that community) using a decryption key. The community may be generated on a security information sharing platform based on a set of community attributes. The decryption key may comprise a private key corresponding to each user attribute of a set of user attributes that are associated with the authorized user where the set of user attributes satisfy the set of community attributes.
