A network and a device can support secure sessions with both (i) a post-quantum cryptography (PQC) key encapsulation mechanism (KEM) and (ii) forward secrecy. The device can generate (i) an ephemeral public key (ePK.device) and private key (eSK.device) and (ii) send ePK.device with first KEM parameters to the network. The network can (i) conduct a first KEM with ePK.device to derive a first asymmetric ciphertext and first shared secret, and (ii) generate a first symmetric ciphertext for PK.server and second KEM parameters using the first shared secret. The network can send the first asymmetric ciphertext and the first symmetric ciphertext to the device. The network can receive (i) a second symmetric ciphertext comprising double encrypted second asymmetric ciphertext for a second KEM with SK.server, and (ii) a third symmetric ciphertext. The network can decrypt the third symmetric ciphertext using the second asymmetric ciphertext.

This disclosure provides methods, devices and systems that facilitate mobility of wireless communication devices configured for multi-link operation (MLO). Particular aspects more specifically relate to facilitating fast basic service set (BSS) transitions by wireless communication devices that support MLO. For example, some aspects provide support for station (STA) multi-link device (MLD) roaming between access point (AP) MLDs, from an AP MLD to a non-MLO AP, or from a non-MLO AP to an AP MLD. In some aspects, a STA MLD may be configured to use a medium access control (MAC) service access point address (MAC-SAP address) of the AP MLD when re-associating or communicating with a legacy AP or with an AP MLD. In such aspects, the MAC-SAP address may be used by all STAs of the non-AP MLD for fast BSS transitions.

This document describes a three-party cryptographic handshake protocol in a wireless network in which a sighter receives, from a beacon, a packet including an exponentiation of a random value and a proxy value and generates an end-to-end encrypted ephemeral identifier (E2EE-EID) from the exponentiation of the random value and the proxy value. The sighter generates a message for an owner, selects a private key, and computes an exchanged key using the private key and the E2EE-EID. The sighter extracts a common symmetric key from the exchanged key, encrypts the message using the common symmetric key, and transmits the encrypted message to the owner.

Secrets such as secure session cookies for a web browser can be protected on a compute instance with multiple layers of encryption, such as by encrypting key material that in turn controls cryptographic access to the secret. A compute instance can be instrumented to detect when a process attempts to decrypt this key material so that the process requesting decryption can be compared to authorized or legitimate users of the secret.

The techniques herein provide for enhanced overlay network-based transport of traffic, such as IPsec traffic, e.g., to and from customer branch office locations, facilitated through the use of the Internet-based overlay routing infrastructure. This disclosure describes a method of providing integrity protection for traffic on the overlay network.

The present disclosure relates to methods and apparatus for flexible, security context management during AMF changes. One aspect of the disclosure is a mechanism for achieving backward security during AMF changes in idle mode. Instead of passing the current NAS key to the target AMF, the source AMF derives a new NAS key, provides the new NAS key to the target AMF, along with a key change indication indicating that the NAS key has changed. The target AMF sends the key change indication to the user equipment.

A method in a User Equipment (UE) of an Evolved Packet System (EPS) establishes a security key (K_eNB) for protecting Radio Resource Control/User Plane (RRC/UP) traffic exchanged with a serving eNodeB. The method comprises sending a Non-Access Stratum (NAS) Service Request to a Mobility Management Entity (MME), the request indicating a NAS uplink sequence number (NAS_U_SEQ). The method further comprises receiving an indication of the NAS_U_SEQ of the NAS Service Request sent to the MME, back from the MME via the eNodeB. The method further comprises deriving the K_eNB from at least the received indication of the NAS_U_SEQ and from a stored Access Security Management Entity-key (K_ASME) shared with said MME.

In one aspect, a system for managing data processes in a network of computing resources is configured to: receive, from an instructor device, a parent request for execution of at least one parent data process executable by a plurality of computing resources at least one computing resource; generate at least one child request for execution of at least one corresponding child data process for routing to at least one corresponding destination device, each of the at least one child data process for executing at least a portion of the at least one parent data process, and each of the at least one child request including a respective destination key derived from at least one instructor key; and route each of the at least one child request to the at least one corresponding destination device. The at least one child request can be obtained by a supervisor server via the routing.

A system, method, and computer-readable recording media for a user account secure with a single sign on (SSO) password hidden authentication. Receiving credential information (CI) and generating the SSO password through at least one client device (CD). Encrypting the SSO password. Storing the SSO password in the CD and an electronic device (ED). Transmit the SSO password and encrypted SSO password to a cloud services platform (CSP), where the CSP stores both. Storing the SSO password in a cloud server (CS). Accessing the user account, if SSO password is unavailable, through the CSP transmitting a one time passcode to a user email, the CD setting a temporary password transferred to the CSP. The CSP confirming a match and transmitting the encrypted SSO password to the CD, the CD decrypting the encrypted SSO password and resetting the temporary password to the SSO password.
